Anaerobic digestion is a unique way to dispose of organic matter in an ecological way. During anaerobic digestion waste is broken down in areas where there is very little or no oxygen at all. The waste is mainly converted into gas form while the remainder is kept in solid form. The waste products produced can be used for other purposes in an ecological manner reducing the amount of waste to be disposed.
The following article explains how anaerobic digestion is used to reduce the amount of waste we dispose and put it to economical uses.
Anaerobic Decomposition Process
Anaerobic digestion is part of a system known as anaerobic decomposition. Using an anaerobic digester organic waste products can be broken down into new forms which can be effectively recycled and put to good use.
Waste treated by anaerobic digester systems can be used for a variety of uses. Biogas is one of the main products that can be used to supply energy to electricity generators, power heating systems and to make nutrients for soil. Anaerobic digesters are commonly used for disposing of sewage and treating animal waste. As the world tries to become more green and efficient with its recycling and reuse of waste products the use of anaerobic digesters has increased.
By using these systems more we can reduce the amount of waste that would otherwise be incinerated causing more harmful emissions to escape into the atmosphere. Anaerobic digestion also reduces the need for landfill sites which also ultimately release harmful products into the earth’s surface.
Biodegradable Waste
A variety of waste products that would otherwise be incinerated or added to landfill sites can be treated using anaerobic digestion systems. Waste products that are biodegradable can be disposed of in a more efficient manner than conventional means.
Waste that can be treated includes paper, grass clippings and other garden waste, food leftovers and sewage. Using the right combination of organic waste can boost the efficiency of an anaerobic digester and can improve the rate at which the reaction occurs. In order to maintain an efficient rate of biogas and useful by products conversion it is necessary to sort the incoming waste appropriately. This involves screening the incoming waste for materials which are non biodegradable and hinder the system from functioning.
Before organic waste is entered into the digester potentially hazardous waste is identified and removed. Materials such as metals, plastics and other synthetic materials need to be taken out of the system to prevent it from lowering the quality of the new energy produced or stopping the system from functioning altogether.
