One can find a lot of different methods of waste disposal, but they all have one thing in common. They all involve the removal or recycling of unwanted or unused items. Waste disposal methods are required for every household and office because there are no two people who do not own items that need to be disposed of. Waste can come from a number of sources including car engines, food packaging, and even electronic equipment and telephone cords.
Composting, usually performed for backyard organic gardening, happens by letting unwanted organic materials sit for long periods of time before finally decomposing it. This process is known as aerobic composting and is considered to be among the most effective methods of waste disposal. It also allows for the removal or recycling of the most commonly found and hazardous wastes such as lead, arsenic, mercury, and polychlorinated biphenyls (PCBs). Note that aerobic composting is considered to be among the very best methods of waste disposal because it can turn toxic organic wastes into highly safe, renewable, and non-toxic compostable materials. These, in turn, can then be used to create materials for both residential and commercial use.
The second popular methods of waste disposal in recent years has been the utilization of landfills and incinerators. The construction of new landfills continue to increase at an alarming rate while the growth of landfills in the U.S. is now the highest in the world, as more families are being forced to build homes on land that is already occupied by dozens of thousands of unused and unwanted homes and cars. Unfortunately, many landfills continue to fill up with harmful chemicals, household waste, and other materials that will take centuries to degrade in the landfill. The problem, however, is that traditional methods of waste do not account for the way that landfills decay, which makes recycling and landfilling even more detrimental to our environment.
The development and implementation of new methods of waste disposal has thus become necessary in order to address these issues. One method that has come to the forefront as a viable solution to the problems associated with toxic wastes is the adoption of closed systems. Closed systems are waste disposal methods that involve the separation of chemical contaminants in their raw form (in their original source) from the waste that they generate. In some cases, this includes materials like used oil and other hazardous fluids. In others, it involves the separation of highly flammable liquids like gasoline and paints thinner. The latter two types of hazardous waste, however, require different methods of waste disposal because they can cause serious environmental hazards when disposed of.
These methods of waste disposal are generally more effective than methods of waste disposal that rely on open systems. The most common open methods of waste disposal include ground and surface burials. Ground burial sites provide an ideal location for a buried waste septic system because the soil provides an ideal soil temperature and acidity level for bacteria to thrive. On the other hand, surface burial sites usually involve excavation and the use of heavy equipment. Despite the setback posed by these methods of waste disposal, however, they are still preferred by a majority of households and businesses because of their relative simplicity and relative effectiveness. For example, solid wastes that do not burn easily or have high melting points can be interred in shallow graves made of earth, with the help of heavy-duty metal burial lids.
Another important solution to the problem of waste disposal is recycling. Most developed countries have developed efficient recycling systems that make use of both conventional (food ingredients and household cleaners) and advanced technology (sealed in plastic liners and freezers). These recycling methods are also more beneficial to the environment than the more traditional methods, which tend to emit large amounts of carbon dioxide into the atmosphere. Because the recycling industry has developed so effectively, it has become a key source of job growth in most countries. In addition to helping reduce unemployment, recycling reduces the amount of garbage that ends up in landfills and contributes to the overall health of the nation’s ecosystem.
Another method that has helped many landfills stay fuller and less overflowing is the burning or incineration of organic waste. Because many landfills can only handle a certain amount of organic waste, especially the non-recycled ones, the combustion of organic waste is a good way to help solve the problem of over-exploiting a landfill. Thermal treatment, on the other hand, involves compressing and heating waste materials until they become soft enough to allow gas or liquid to pass through. This liquefying process, however, must be done very carefully in order to prevent explosions, so it is often used in tandem with incineration.
These are three different methods of waste disposal, each with its own pros and cons. If your town has a limited amount of land for waste storage, or you are concerned about the effects of landfills, there are still other methods of waste disposal available. One of the most environmentally friendly methods of waste disposal that everyone should consider is recycling. It is a convenient way to both dispose of unwanted waste and contribute to the reduction of garbage, as well. Recycling programs are beginning everywhere, from cities to suburbs, and anyone who wants to help the environment can certainly benefit from recycling. And because it can be recycled again, you never have to live in fear of running out of space in your home.
