5 Different Types Of Waste Disposal Methods
Many industrialized nations are having problems when dealing with waste disposal. Some hazardous waste such as radioactive remains and no-biodegradable waste are common problems when trying to identify the best method of disposing of them. These toxic waste can cause a whole lot of damage to human lives and the environment at large.
Waste disposal is, however, not a new issue, but an issue that has evolved for many years. The growing population, which results in higher proportions of waste is what is bothering most countries. Some waste disposal methods have been enhanced and advanced over the years, but they are not enough for the growing population. Below are some of the trusted and effective ways of waste disposal that have been used over the years.
Types of waste disposal in London
- Sanitary landfills
This is where the non-recyclable waste is disposed of. The landfill is where all the non-recyclable waste is separated and spread over a protective base. The waste is then covered with layers of soil, and the area is left for other activities except building on that area to give room for decomposition to take place. The area is left for around 25 years so that the waste will decompose.
Some requirements should be met before an area is considered a landfill. One of the requirements is that the area should not be prone to floods. This requirement is meant to ensure that no harmful waste will find its way to the water zone level through flooding. The landfill also should have non-porous soils and low levels of groundwater.
The landfills are however maintained from time to time by some skilled workforce.
- Disposal in seas and oceans
This method of waste disposal is one that has brought about a lot of controversies all over the world with environmentalists pointing out the dangers marine life is exposed to. However toxic wastes generally in the form of radioactive materials are disposed of far off in the oceans far away from human habitats. The rubbish disposed of in the seas and oceans sink deep into the water where no human can reach hence protecting humans from being affected negatively from the radioactive type of waste.
This method of waste disposal in London involves burning waste in airtight containers known as incinerators. This method is one of the most effective and useful because the by-products of burning waste can be reused. Heat can be used for energy while the ash can be used for hydroponic purposes.
This method is also considered very cheap and famous for reducing the amount of waste in London by 95%. Some toxic waste such as hospital waste can be disposed of using this method since it does not leave any type of waste hanging around unlike disposing of such wastes in a landfill.
The heat generated from incineration can be used as energy for cooking, supplying heat to turbines and heating. However, this method of waste disposal in London requires strict vigilance to avoid harmful toxins such as dioxin from the incinerator lines from contaminating the surroundings. Accidents might happen, so the incineration process has to be conducted very vigilantly.
- Recycling and reusing
This a common waste disposal method in London today. This method involves transforming the wastes into new products through different industrial processes. Paper, glass, aluminum, and also plastics are usually recycled. This method is environmental friendly, but the industrial processes can be costly.
Wastes like plastic bags and plastic bottles can be reused instead of throwing them off to nature. Many waste materials can be reused instead of throwing them away. This waste disposal method is environmental friendly since it does not in any way pollute the air or the water.
This method also reduces the number of landfills in the area, thus giving more space to other essential activities. Recycling and reusing are one of the ways that are very speedy and efficient. Reusing also saves a lot of resources since the money you could have used to buy new items like plastic bottles can be saved or used in another way.
- Biogas and fertilizer production
Gardeners, farmers, and homeowners who produce large amounts of organic waste can use this method of waste disposal to generate fertilizer out of the waste. This type of fertilizer is very advantageous since it is all organic. Homeowners who also own gardens can create compost pit where they can keep all the organic waste to generate fertilizer for their gardens. Homeowners can go through Household waste removal tips for reducing the amount of waste generated.
For bio-degradable waste, bio-degradation companies will turn these types of waste into biogas by using fungi and some types of bacteria to decay the waste and subsequently generate biogas from the decayed waste. The biogas produced is then used as fuel for different purposes. This method is excellent when it comes to organic and biodegradable waste since it results in by-products that can be used later.
