Gasification Sees a New Dawn and How it Will Benefit Us All

Gasification Sees a New Dawn and How it Will Benefit Us All
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Against GM Foods
Posted on March 12th, 2010 No comments
Against GM Foods
Genetically modified (GM) foods are not being found to be safe for humans, or for the environment. There are a number of reasons why there a growing number of people are against GM foods. Are Genetically Modified Foods Safe? The reason to resist the growth of GM food in our diet is that it has a negative impact on our environment; plants and animals grown organically are not distorting their genetic makeup.
And in the rush to accelerate the production of genetically modified foods, scientists are short cutting testing methods. Recently, the United States Tufts University, School of Medicine was involved in testing the effects of genetically modified rice directly on children (by-passing the usual practice of testing on animals). This direct testing on children created controversy and a formal letter of protest from 22 international scientists to the University; the protest letter has been made public through various social media.
The letter protested the use of children as a breach of medical ethics code since children cannot legally give their consent (since it is not deemed to be informed consent) to participate in experiments. As Professor David Schubert, Salk Institute of Biological Studies said, “…it is completely immoral to feed this rice to children without proper safety testing … [i]t’s like putting a new drug on the market with no toxicology or safety trials”.
In defense of their position, the Golden Rice Organization issued a press release that states they “…us[ed] the correct Chinese and US government approved processes, the trials in China went ahead last year with the formal approval of their parents and the understanding of the children”. How do children understand the impact of genetically modified food on themselves or the environment? It’s a complex subject that many adults have a hard time understanding. Also, how can anyone (parents, children, or testing scientists) understand what the long term effects of genetically modified “golden rice” are on the human body without prior study or testing?
More importantly, will the overall risks of genetically modified foods over time out weigh the alleged benefits? Farmers have cross-bred plants and animals for hundreds of years to improve their products. Improvements to size, produce yield, taste, hardiness have been achieved through relatively natural means and within nature’s own boundaries; different species were not bred together.
With the discovery of DNA and a method of gene extraction, the concept of genetic modification was born. The intent of genetic modification is to create food that grows quickly, yields much, is resistant to pests, to disease, and to other natural events. However a number of scientists respond that the benefits are not worth the risks; genetically modified foods often become resistant to herbicides and pesticides requiring ever increasing amounts. There is the suspicion (still unproven) that pollinating bees have been affected by the increasing use of these chemicals and that both pollinator and predator species have been affected by the genetically modified crops (also known as transgenic crops) through habitat destruction and use of dangerous herbicides and pesticides.
Since the introduction of genetically modified foods, some scientists are reporting that food-related illness has increased. The only published human feeding study confirmed that genetic material in genetically modified soy transferred into the DNA of intestinal bacteria and continued to function. What long term impact will these foods have on the population and the environment? There are many more potential risks in the development of genetically modified foods. Animals that were fed genetically modified feed appeared to suffer from increases in fetal death, low birth weight, sterility, and more. The concern is that human reproductive failure and sterility or infertility will be long term consequences to using GM foods.
In the US, the Department of Agriculture reports that cotton and corn crops have been genetically modified to produce their own Bt toxins since 1996. Bt modified crops are insecticidal crystal proteins and are considered effective against crop-damaging caterpillars. The toxins are considered important for pest control and since resistance to herbicides and pesticides is growing, the sentiment is that these genetically engineered Bt toxins will help to protect the crops. The issue with the GM Bt toxins is that they are considered serious allergens; ever wonder why so many more children and adults are exhibiting allergic reactions than ever before?
The problem with genetically modified foods is that there is also a reaction for the action; unfortunately, globally, in our rush to grow food supplies, we have not taken the time to properly test and research the long term impacts and effects of genetically modified foods. It is easy to be against GM foods - our planet is at risk.

Save the Planet - Sell Your Laptops
We’re in this environmental mess because humans have exploited the earth for personal gain. However, you can sell your laptops, get some grocery money and still help the planet.
Steer clear of the attitude that everything is disposable after a few uses; do your part and extract the most out of your electronics. In carelessly tossing away our possessions, we are the reason that one more thing spends an eternity in a landfill. Electronics, including laptops, are one of the most significant sources of toxic heavy metals, including cadmium, lead and mercury, leaking into the soil, according to the Environmental Protection Agency.
Pollutants do no simply stay within the confines of the landfills, but are transported through waterways and through the air. When toxic metals travel upward during evaporation, these toxins contribute to acid rain, spreading the heavy metals for miles. Dr. Lorris G. Cockerham, former professor at University of Arkansas and researcher, wrote that build up of toxic heavy metals in animals damages their vital functions and hinders growth in plants, therefore irrevocably harms ecosystems.
The heavy metals seep into waterways and into our water sources. These heavy metals can enter our body through the ingestion of contaminated water, harming our bodies. Even a low concentration can harm us, according to James Girard, author and professor at the American University.
A solution? Sell your laptops to a recycler. When you sell your laptops, the laptop parts find new life with computer repair shops and wholesalers, avoiding certain doom in a landfill. Selling laptops is an easy process for the average time-constrained American worker. Search for “sell laptops” on the Internet. Locate a recycling company who will accept the laptops you are selling. Lastly, look for the V logo that signifies the company is verified organization, not a Nigerian scam. Many business will offer an instant quote on their Web site for the laptop you are selling. Input the specifications of your laptop, follow directions and you have check or a PayPal payment for your laptops.
Make sure you choose a reputable company to sell your laptops to. Some companies boast a “green” philosophy, but actually ship laptops to landfills in developing countries. We all have a part in this green earth and many of us have take steps to follow the mantra, “reduce, reuse and recycle.” Many people think about selling their cans, bottles and such and don’t think about their computers. Do your part, keep our Earth Green and sell your laptop.

Environmental Improvements - Calling Leaders

Environmental Improvements - Calling Leaders
The environment, which its current emphasis on ‘Global Warming’ and ‘Climate Change’ important though it is, is not the most vital matter facing humanity.
During recent speaking and teaching visits to Uganda and Kenya, and hearing something of the actual situation, I have become angry and occasionally tearful at the gross injustice, greed and corruption which is rife.
Our world has become so unstable over these past months in a way totally unpredictable by man. If I had written prophetically, 15 months ago, about what we are presently experiencing in the area of finance, you would have said I was off my head and just daft!
The Carbon Footprint issue might be causing some environmental damage although is being question by many, but the financial greed and mismanagement footprint is hurting millions as people loose income, jobs, houses and basic security.
When I was in Kenya last November, I was informed that the economic problems hitting America and Europe would hit Africa in three months time, and visiting schools and orphanages in the various slum areas I was very much aware of how a little extra resources could help so many more people with very little effort.
The structures are in place to utilise and distribute AID in a responsible manner. I have seen the projects designed to help those whose lives are confronted with unnecessary suffering, one example of this in Methere in Nairobi and the River of Life School in Manyatta, Kisumu. Now, there are other projects and schemes in various other nations and by investing in these immediately, the environment would improve slightly within a few months, but for the people who live there the improvement would be immense.
I write this as the G20 Summit is meeting in London. The money spent on that alone could feed the poor in Kenya (or some other nation) for months. It is just that I know a little about Kenya.
Earthquakes, floods and droughts will continue, and these will undoubtedly increase, with environmental disaster and tragedy resulting, but what concerns me is the area where substantial and significant improvements could be made, if only leaders would make sensible wise decisions.
You see, I write as a committed disciple of Jesus Christ, and I am not given the option of being quiet on these issues.
One sentence really challenged me this week. If you were reading the Sermon on the Mount for the first time, in Matthew’s Gospel, Chapters five to seven, how would you change your life?
How might this motivate us in the areas of fresh water and sewers, immunisation and basic health services, and feeding programmes and education for those who genuinely want to study and contribute positively towards the welfare and well-being of their nation.
To make these environmental improvements, strong, radical leadership will be required, but it is often in times of real darkness that the risen and living Lord Jesus Christ chooses, redeems, and raises up a leader or leaders to shepherd people out of their predicament.

Cheap Flights and Climate Change - Do We Want Too Much?

Cheap Flights and Climate Change - Do We Want Too Much?
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.
All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

A Global Disaster From the Perfect Solar Storm
The average solar cycle lasts for eleven years. The cycle includes a minimum of solar activity and a maximum. The sun is unusually quiet right now and has been for some time but there should be an increase in solar activity at some point in the near future.
The best current scientific estimate for the next solar maximum is 2012. If this estimate is correct, there is still a few years to try and prevent the potential of a future global disaster. A disaster that would begin on the surface of the sun and could end with tragedy on earth.
The surface of the sun is a mass of plasma that contains highly charged energy particles. Once in a while, some of these particles escape the suns surface and a mass of plasma travels through space on the solar wind. This process is known in scientific terms as a coronal mass ejection but it can also be called a solar storm.
A disaster for the planet would occur if a solar storm reaches and hits the earths magnetic shield in just the right way. If it were to happen, millions of people would lose their lives and the planet would be thrown into chaos as the technology that has become crucial to every day living suddenly gets taken away.
The perfect solar storm will start with skies that will be filled with a bright red aurora. However, soon everything will become dark as every electric bulb becomes devoid of light. The storms damage to the electric grid would be caused through an increased DC current. The runaway current would knock out and melt hundreds of key transformers within minutes, cutting off power for hundreds of millions of people.
Those damaged transformers cannot be repaired only replaced and installing a replacement takes a well-trained crew a week or more. Its incredible to consider that most major electrical utilities have just one or two suitably trained crews available for these type of transformer repairs. In addition, there are only a few spare transformers available and the rest would have to be built to order. Its a process that can take nearly twelve months.
So, the power blackout from the perfect solar storm would last for months but its not just the absence of light that would be the problem. Drinking water would still come through the taps for maybe half a day after the storm. With no electricity to pump water from reservoirs, there would be no more tap water after that.
The electric grid is necessary for almost all natural gas and fuel pipelines to operate. As a result, fuel and natural gas will quickly run out and without food delivery, supermarket shelves would soon become bare. Soon it would become necessary to control public hysteria and the military would have to be called in to restore civil order
There will be no power for heat, cooling or refrigeration until the grid is repaired and after their back up generators run out, hospitals will not be able to provide modern healthcare. A lack of water and food will result in spreading disease but Pharmaceutical companies without electricity will not be able to produce the necessary medicine.
Of course, many will say that this is absurd science fiction and it cannot happen here, but this chilling disaster scenario was outlined in a report released last January (funded by NASA) by the US National Academy of Sciences (NAS).
The fact is that a storm from the sun did hit the earths magnetic field in 1859. The effect of this solar storm on earth became known as the Carrington Event. The event was named after the amateur astronomer who observed two patches of intensely bright and white light emanating from a large group of sunspots that may have produced the event.
The solar storm that produced the Carrington Event created a red aurora across the planet from the poles to the tropics. Throughout the world, telegraph systems crashed, machines burst into flames, and electric shocks rendered operators unconscious. Compasses and other sensitive instruments reeled as if struck by a massive magnetic fist. It can happen again and the technology of the planet is now much more advanced and vulnerable.
The next solar maximum is estimated to return in about three years. A global disaster from the perfect solar storm can be prevented with proper contingency planning. There is still time for the government to be proactive and prepare to avoid disaster by creating a potential response to quickly repair the damage to the electric grid from the perfect solar storm.

Recycle - Composting Food Waste Takes Care of Two Things at Once
Years ago my dad taught me the benefits of composting food waste. It had nothing to do with any type of “green” movement or being environmentally friendly, no, it had everything to do with reintroducing nutrients back into the soil.
Here is what he taught me then and it still holds true today. By burying your food waste and kitchen scraps (no steak bones though), you are providing a quality food source for the creatures that live in your soil. From micro organisms and those creatures that the human eye can not see, up to worms, which of course we do see.
See, what happens is these creatures eat the food (and of course each other) and then finally the worms eat basically everything and their castings (worm poop) create the best nutrients your soil could ever have. By continually supplying your garden soil with food waste you are feeding the earthly creatures and they reward you with healthy soil. Now where can you get a trade off like that!
Ok so here is how you do it. Get yourself a fairly large Tupperware bowl. One large enough to hold at least a week’s worth of food scraps. Then after each meal dump everything and anything into that bowl. Just do not put steak bones in there, they wont biodegrade or be eaten by the worms. Banana peels, apple peels, coffee grinds, fish, vegetable scraps, egg shells and basically anything you don’t eat, all qualifies.
When your Tupperware bowl gets full, take it out to your garden and dig a hole about a foot to two feet deep and then dump the food scraps into the hole. Fill in the hole with the dirt and mark the spot with a stick or something else so that you do not dig up that area again for another three months. You need to give those little rascals some time to eat it all.
Now you simply repeat this process as the Tupperware bowl gets full. If you find that you live in colder climates where the ground may freeze for lengthy periods of time, then consider starting a warm box to recycle your food scraps. That goes beyond the scope of this article but I am sure if you Googled the search term “vermicompost” you will get all the information you will ever need.
So what are the two things I was talking about earlier? Well obviously the first is you are adding nutrients to your soil through composting food waste. The second is by composting your food waste you are limiting the amount of garbage that ends up in a landfill. The average four person house hold creates about 8 pounds of food waste per week. If every family in America followed this process we would eliminate nearly one billion pounds of food waste garbage a year. Now that is a lot of trash!
Do your part and compost your food waste. The worms in your garden will love you for it and so will everyone else in the environment.

Water Efficiency
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day - or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.
The cleanest kilowatt is the one never used:
Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

Saving the rainforests and environment is not an easy task. It took many years of neglect, mainly on our part, in keeping the environment clean. We polluted our air and our water through chemicals and different types of bacteria and debris. We used paper products that were not recyclable and or were not biodegradable.
Rome wasn’t built in a day as the old cliche states, but we managed to ruin our planet over the years and unfortunately it will take longer than a day to rid the Earth of all the garbage we have dumped on it. It is so easy to throw a piece of paper out of your car window, instead of finding a receptacle to dispose of it, or to throw empty cans in with your regular garbage instead of separating them for the recycle pickup or to bring bottles back to the store. Let’s not forget the broken down refrigerators, t.v.s, mattresses, etc on the side of the road.
I have traveled to third world countries and it breaks my heart to see that. They have no means of garbage disposal and they certainly don’t know how to recycle. Most of the people, although poor, take pride and keep their properties neat and debris free, others do not care. The same goes for people who live here on Earth. Some are proud of what they own and others could care less.
By the inch it’s a cinch, by the yard it’s hard. If we all do our part in what ever little way, we can help improve Mother Earth and make it liveable for generations to come. Let’s start by picking up our litter, don’t let the water run when brushing your teeth, use rags instead of paper towels, carpool if you can, don’t discard items on the side of the road to make it look unsightly, but for the most part…. Be Proud Of Where You Live and What You Have!!!!!!

Once a product has completely served its purpose, what remains are post-consumer materials that would otherwise be disposed as waste but are instead recycled. This would include products such as old packaging, glass bottles, aluminum cans, and plastics. When you recycle from your home these products become post-consumer recycled.How is this different vs recycled? Regular recycled materials can contain a combination of materials, often coming a scraps or other by-products as a result of manufacturing. This could include both pre-consumer and post-consumer waste.

VOCs are organic chemical compounds that have high vapor pressure and easily evaporate at room temperature. VOCs can be released from many household items such as paints, flooring, upholstery, and cleaners. These VOCs are not only air pollutants but have also been known to cause health effects as well.
Look for: Low-VOC, Zero-VOCBisphenol A (BPA)
BPA is an organic compound that is used in the creation of many plastics and resins. Most commonly you will find BPA used polycarbonate bottles. While there is some controversy about the effects of BPA, some research has raised serious health concerns about the usage of BPA.
