Most countries with developed industries are struggling with the difficulty of waste disposal. It is difficult to find safe ways to dispose of waste especially the non-biodegradable and hazardous wastes. These wastes can have a negative impact on the environment and people’s’ health. It is therefore important to dispose of waste properly to keep the environment clean and also to protect people from contamination. Luckily, ways of garbage disposal have been devised to help reduce the amount of waste.
Below is a list of 6 Different Types of Waste Disposal:
This process involves non-recyclable wastes. The selected area of the landfill should have low levels of groundwater and should have non-porous soil. The area should not be prone to flooding too. A base first created to prevent harmful chemicals from reaching the water zone below. After that, the wastes are carefully separated and spread out on the protective base. Later on, layers of soil are spread on top of the waste and compacted. The Landfill area can then serve as a leisure ground or park at least until the wastes decompose. This could take up to more than 25 years hence no construction should take place in the landfill area
Biogas and Fertilizer Generation:
Organic wastes can be used to create compost that will, later on, be decomposed naturally into nutrient-rich fertilizer. This is mostly used by farmers or homeowners with a large amount of organic waste. The type of fertilizer formed is advantageous to plants since it’s all organic. Biodegradable wastes can also be used to create biogas. Bio-degradation companies turn these wastes into biogas by using fungi and bacteria to decay the wastes. The biogas generated is later then used as fuel. This method is very efficient for organic and biodegradable wastes.
This is another type of waste disposal that involves the use of worms to help decompose wastes. A specific type of worms is used to feed on the wastes and digest them. This process not only helps with waste disposal but also helps improve soil nutrition. The excretion of the worms adds nutrients to the soil, this improves the quality of the soil leading to a better growth of plants.
Recycling and Reusing:
Recycling and reusing is another effective means of disposing of wastes. Wastes such as glass, rubber, plastic or wood can be transformed through industrial processing into other useful products that can be used again. You could also reuse items such as plastic bottles and paper bags instead of throwing them away. This will greatly reduce the amount of waste you have and also help you save money that you could have used to purchase new plastic bottles or paper bags.
Disposal by Incineration:
This process involves the burning of wastes in airtight incinerators. This process is cheap and very efficient as it reduces the size of the wastes by up to 95%. The by-products of incineration such as heat and ash can be used for energy creation and hydroponic purposes respectively. The energy can later be used to provide power in the industry. This method is commonly used for toxic and hazardous wastes.
Disposal in Water Bodies:
Hazardous wastes such as radioactive substances are usually dumped into large water bodies such as oceans and seas. These type of toxic wastes sink deep into the water to avoid their contamination from reaching human beings.
The above 6 methods are so far the most effective and reliable methods to dispose of waste products. In addition to that, they are safe as they reduce the risk and chances of human and animal contamination.
