Currently, (and thankfully) the world at large appears to be waking up to the need to preserve the delicate equilibrium of planetary conditions that allow us to inhabit our little blue planet. Global initiatives to promote recycling schemes, renewable and sustainable fuels and energies, and more sophisticated forms of waste treatment have begun to creep into the political discourse and the paradigm in construction and power industry legislation seems to have begun shifting already. There are a few methods of treating, disposing and breaking down waste products that are currently in development and testing stages, but could potentially represent the waste treatment of the future.
Pyrolysis: Biological waste products derived from industrial or household wastes can undergo this treatment to form biofuels. You may recognise the “lysis” suffix from other processes- like electrolysis , pyrolysis refers to the decomposition of chemical bonds via heat. Other outputs of the process produces the chemicals that can be recycled into fertilization agents, coke for use in metallurgy, production of pyrolytic carbon, carbon fibres and certain food additives.
Anaerobic digestion: This actually refers to a host of chemical treatments that break down complex, insoluble molecules in the absence of oxygen, making their constituent components available for bacteria to decompose. This is extremely applicable to conditions in landfill sites, where the insulation of the site inhibits oxygen flow through the buried waste, preventing decomposition. The additional benefits include the reduction of landfill gases into the atmosphere, and the production of biogas fuel – this can be used directly as cooking fuel or to drive engines. Biogas along with other liquid bio – fuels is thought to be the solution to the problem of dwindling fossil fuel reserves. The process also outputs a potent fertiliser.
Plasma Gasification: This one is an exciting one. Using a plasma torch called an “electric arc gasifier”, organic waste is reduced to biological fuel and solidified waste in a reactor. This process is designed to break complex molecules into their constituent atoms and be a net generator of electricity – killing two birds with one stone.

Yellow jackets are notorious stinging insects and can be recognized by their yellow and black stripes. They can be annoying and dangerous, so everyone should learn how to kill yellow jackets. First, you have to make sure that you are going to kill yellow jackets safely. In addition, yellow jackets are very dangerous and knowing how to kill yellow jackets is a must.
They can be found in the ground, so you should know how to kill yellow jackets in the ground. Killing yellow jackets in the ground is more dangerous than killing them in the air, because when they are on the ground they are in colonies and they attack people all at once. You have to pay attention when you are going to kill yellow jackets, because they are very dangerous to people.
In addition, if you want to kill all the yellow jackets you should know how to kill yellow jackets nests. The nests can contain over ten thousands yellow jackets, so you have to be very careful not to be attacked by these notorious stinging insects. If you exterminate them you will make your yard safer. As I said above, yellow jackets can be very annoying and everybody should learn how to kill yellow jackets. Click Here to learn more about killing yellow jackets.06.26.12
Sometimes the scale of the world can be dizzying. For example, I know what a billion is, conceptually. My brain can comprehend that number. I can multiply or divide it. I can add or subtract from it. But when I try and consider a billion of something in real life, an actual, tangible billion, I’m at a loss. I can picture ten people in my head. I can see them stood there, in a room, some of them pacing, some of them tapping their feet impatiently. Maybe absently picking their nose, or sniffling. I can see their faces. If you ask me to picture a billion people, I’m lost. The best I can do is imagine a crowd from afar, a placeholder concept that merely represents an unaccountably large number of people. I can’t see their faces, or make out anything distinct. There isn’t really a solid number there I’d probably picture the same crowd if asked to imagine 50,000 people.
I think that this is why, as a species, we humans aren’t very good at dealing with things on a global scale. Think about the difficulty of large scale issues like world economics or waste treatment. Put us in charge of governing an 11 man team and we can do a sterling job. Put us in charge of a country and things start to go wrong. We’re not able to parse that amount of information simultaneously. We don’t have the mental resolution, the imaginary visual fidelity, to cope with concepts of such tremendous scope.
That is why when I hear a fact about the state of our environment as a whole, for example, that the US throws out 22 billion plastic bottles a year; I don’t know how to respond. Is that a lot? It sounds like a lot. But the US is quite big. There are a lot of people there and there are a lot of days in a year. Maybe 22 billion plastic bottles is totally reasonable. I just can’t tell I can’t comprehend numbers of that size without researching the variables involved, sitting down and actually performing the arithmetic.
This is why a lot of the environmental awareness campaigns which advocate relatively simple measures like recycling household waste or turning off the lights if you are not using the room, often employ such surreal and bizarre imagery to try and give us a tangible point of reference. “The US throws out enough paper to build a 12 foot wall from Los Angeles to New York via California every year” or “The residents of Ann Arbor produce enough solid waste (garbage, recyclables, and compost) to fill the University of Michigan Stadium a little over one time each year”. Because, despite the urgency of our situation, the scale of the problem or the amount at stake, we cannot deal with a scale that extends so far beyond what we can immediately see.
