The word biodegradable is a term used to describe materials or items that are friendly to the environment and are considered organic materials. These organic materials decompose back into the soil as nutrients and help minimize waste and pollution. “Organic materials “biodegrade” when they are broken down by other living organisms (such as fungi, bacteria, or other microbes) into their constituent parts, and in turn recycled by nature as the building blocks for new life. The process can occur aerobically (with the aid of oxygen) or anaerobically (without oxygen). Substances break down much faster under aerobic conditions, as oxygen helps break the molecules apart, a process called oxidation.” (Talk). Biodegradation has many factors that determine the rate at which organic compounds breakdown.
Degradation can occur in a period of days to centuries depending on what chemicals are in the organic compound and how they react in accordance to nutrition in soil, water in soil, and the soil’s matrix. Specific nutrients are crucial for chemical reaction within the organic substance to cause

Biodegrading is simply when an item can break down into natural materials in the environment without causing harm. The main difference between the two is that the latter, end, breaks down into “humus” and provides valuable nutrients to the soil. Compostable items have to completely break down and not release toxins, while biodegradable products can leave metal residue. When people throw out their trash, they do not normally consider what will happen to it after it leaves their house. If something is biodegradable, or able to be broken down, it usually goes into a landfill. And once the trash arrives at the landfill, the biodegrading process begins, but it can be very slow. How quickly an item breaks down depends on the reasons previously stated, but some products break down more quickly than others, while other items hardly biodegrade at
One practice enjoying success today is the process of composting. Originally utilized by farmers and in backyards, composting is the natural breaking down of organic materials into soil. The popularity of composting seems reflect people's attitudes and desires to be closer to nature. Compost can occur from levels as small as backyard piles to the heights of corporate composting facilities. When done properly, composting can provide cost benefits and greatly reduce amounts of garbage. Either way, composting is a growing practice that's efficiency grows over time and may become as widespread as garbage collection today.
We need to stay away from the landfills as much as we can so eventually we can get rid of them all together. The benefits of compost include increased soil organic matter content, nutrients for plant growth, replacement of peat moss in potting media, reduced erosion, plant disease resistance, weed suppression and generally improved plant vigor (Barlaz 62). Instead of taking grass clippings to the trash people can leave them laying in the yard to decompose or they can use them to help make their compost. People can even make their own composting bins to use at their homes. There are several reasons why people should compost. If people start composting they can keep their garbage, yard trimmings or leaves from getting to the landfills. Which in turn will keep those things from getting in our water or water supplies. If these things get in our waterways or water treatment facilities it just makes more work for other people. Also by composting people will help their plants look healthier. Sharon Durham talks about manure, composting and how it effects the soil in her article, “Improving on a Time-Tested Technique.” Durham says, “Composting results in stabilization of nitrogen in organic form for use in soil” (20). The soil the plant is grown in will be better and help the plants produce better if you are growing food. “Compost may even be tailor-made to reduce phosphorus availability and
In well-drained soils, organic material, which, of course, contains nitrogen, "may decompose faster than it is replenished (Dolman and Bud, 1967)" (Gambrell, et al, 321). So, in order to s...
The words ‘Reduce, Reuse, and Recycle’ are what a person chants if someone mentions the word recycling. Nicks J defines recycling as ‘[T]he processing of waste materials in order to make them reusable” (11). Individuals who recycle are not just throwing papers in green bins, or cans in blue; in fact, they are helping the environment more than they can imagine. People who want to preserve and protect their planet take the initiative to recycle waste materials. Rather than throwing away old plastic or glass bottles, aluminum cans, and certain types of paper, one can simply recycle them, and they will go through a cleaning and the remanufacturing process to be remade into a new usable item.
The food that they throw away first goes to the dumpsters and then they end up in landfills. This is also where the dumpster divers, or “scavengers” as Eighner prefers to be called, begin their search for food (353). Where he mostly found a great deal of dumpsters was in the city. As he puts it, “the land is now covered with cities,” which means that there will be an abundance of trash that needs to be disposed of (361). This leads to more landfills needed to be made and that takes a toll on the earth. Dockterman has stated that “the buildup of decomposing organic material accounts for 16% of environmentally harmful methane emissions in the U.S.;” these emissions go into the atmosphere that we breath our oxygen from (Dockterman). Not only does this practice affect people survival-wise, but also the earth that billions of people live
Some trash may be biodegradable, meaning that it will decompose and become part of the earth again. Most, however, are not, they just sit there. Within this episode, he shows his audience what they can do on their own to analyze if something is biodegradable or not. The experiment requires you to collect trash and put one piece of trash into a jar that is filled halfway with water. You will then wait a few days, and when you come back you will notice that those that changed such as plant and animal products are biodegradable.
To begin with, in the U.S., trash is most commonly sent to a landfill, unfortunately though, once it arrives there little sorting occurs. According to the EPA, “Nationally, food is the single most common material sent to landfills. When excess food, leftover food, and food scraps are disposed of in a landfill, they decompose and become a significant source of methane, a potent greenhouse gas” (“Cupertino Honored”). At a landfill, trash arriving is only screened for liquids in order to avoid the creation of leachate, or water that is contaminated from dissolved chemicals in garbage. Once screened, dumped, and covered, bacteria begin to decompose the trash and, as a result, release methane, a greenhouse gas 20 times more potent than carbon dioxide. The fact is that landfills are ideally supposed to be used to bury garbage that is non-decomposable, however, with the garbage collection method that is currently in place across many states, all unsorted garbage is being sent there. In addition, “...traditional trash disposal not only wastes material that can enrich soil but accelerates climate change. Organic matter decom...
Recycling has been something that has always been in human society. Even before the modern era humans still used and reused natural resources to survive and develop as a society. Here in the US, recycling didn 't really make its impact until the 1940s, during the second world war and has only started to advance even further within the last 15 years as more efforts for environmental preservation are being made. From schools, and major companies down to individual homes, recycling programs can be found in most countries that are developed. As technology continues to grow many advancements have been made in renewable resources like solar or electrical power. Recycling though being around much longer has only recently made strides like collecting
Soil degradation is a serious global environmental problem and may be exacerbated by climate change. It encompasses physical, chemical and biological deterioration.
Microbial decomposition releases nutrients into the environment that are needed by other organisms. Microbes are also involved in the cycling of many other important compounds in — and between — ecosystems, including oxygen, carbon and nitrogen. Many microbes use the energy of sunlight to convert carbon dioxide to oxygen, which we need to breathe. As they do this, they create new organic material — themselves — which are then eaten by other organisms. In this way, the cycling of nutrients and energy
People need to think about the objects that they throw away, those items can affect the animals around the world. For example, when people throw away the plastic rings that go around pop cans, can kill animals by being stuck around their little necks. So, before people throw those plastic rings out, they need to make sure that they cut a slit into each ring so in case an animal does get stuck in one of them, then they can get out safely. Recycling does not just have to be about plastic, but when the plastic is recycled, Americans can use it for many different things. For example, the plastic can make park benches, plastic crates, and wire tubing. Many people do not understand where all of the recycled objects go, but the objects do not go anywhere they are just recycled to make other things, recycled objects also help reduce the price of the objects that they make. The best part about recycling is the fact that people can recycle almost anything and turn it into something completely different. For example, Keen’s Harvest makes bags, wallets, and totes from recycled airbags that come from automobiles. Another example is Looptworks uses cotton jersey, nylon, vinyl, and recycled polyester to make their upcycled leather iPad cases. Skateback is another company that uses recycled material to make iPhone backs; they use the discarded post-industrial skateboard materials. Vinylux
Recycling is a way to reduce the use of our natural resources and reuse what we can and what we have. Pollution is human activity that can cause change to our environment that may be harmful.
Millions of plastic bags are given out to consumers by supermarkets and stores to carry their goods in. They are also cheap, light, durable, easy to carry and in many cases, free. The most commonly used shopping bag is made of High Density Polyethylene (HDPE). This type is used in the majority of supermarkets and stores. After these bags are used, they often end up in landfills or as litter, roughly only three percent of plastic bags is actually recycled per year (Planet Ark, 2011). The materials used in making plastic bags make them non-biodegradable. According to the science dictionary, 2011 refers to “these materials cannot be decomposed into environmentally safe waste materials by the action of soil bacteria.” These harmful substances are toxic and take approximately four hundred years to break down, or in this case photo-degrade; which is how plastics made from (HDPE) break down. Since they are not biodegradable, they remain in the environment and are absorbed in soil or water (Indian Centre for Plastics in the Environment, 2010). This essay will discuss the various harmful effects of plastic bags, and demonstrate the risks that these bags impose on humans, animals and the environment. It will also discuss a series of suggested solutions that could help reduce plastic bag usage.
An important part of recycling is conservation. Conservation helps keep unneeded waste out of landfills in the United States (Conserve Energy Future 2). As Americans, an average person throws away 4.8 pounds of waste daily. This adds up to over 1750 pounds in a year alone, for one person. In 2006, Americans generated 251 tons of waste (Riedel 11). Of this waste over 50 percent could be recycled into new materials to be used again. In doing this, recycling will tremendously
According to the RRS, “Recycling is a process to change waste materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production. Recycling is a key component of modern waste reduction and is the third component of the ‘Reduce, Reuse and Recycle’”.
