Waste Management And Recycling
By: Ross Bainbridge
Collecting, transporting, processing and disposing waste material is known as waste management. The aim is to clean up the surrounding environment and see that the waste does not have a detrimental effect on our health. Nowadays waste management has gone a step further and not only plans proper disposal but also attempts to see whether we can reuse and recycle certain materials from waste matter.
Waste management differs from country to country and in urban and rural areas. How waste is managed in a commercial industrial area will be very different from how it is handled in a residential area. In residential areas it is usually the responsibility of local government bodies while in industrial areas it is the industry responsible for creating the waste.
The most commonly followed waste management systems involve collection and disposal of waste, the commonest way of disposal being landfills and incinerators.
Landfills are the most common practice in many countries as it is a relatively inexpensive method of disposing of waste materials. These were often created in disused quarries or mining voids. The disposed waste is usually compacted and covered to prevent vermin and wind-blown litter. Landfills usually have a system to extract the gas that the decomposing waste matter generates. Opposition from adjacent landowners especially in urban areas have made it difficult to establish new landfills and the authorities have to transport it further away for disposal making disposal more expensive.
Incineration destroys waste material by burning it. Regarded as a practical method of disposing of hazardous waste materials, it has of late, become controversial for many reasons such as the fact that it creates toxic gas and ash, which can harm local populations and pollute groundwater.
Experts have classified waste into different hierarchies. One group has coined the term
‘3 Rs’ ‘Reduce-Reuse-Recycle’ to classify waste. The main aim of such classification remains the same – produce less waste and reuse as much as you can.
