Understanding Waste Recycling

When waste is not properly managed it can damaged the environment and also cause loss of valuable resources that could be put to better use, thereby saving business and consumer money. Waste that is not disposed properly is known as litter. Biological waste is any unwanted substances or toxins that are expelled from living organisms, examples of this waste are urea, feces and sweat, Modern System Management defined waste into the following category:

1.      Hazardous waste which includes industrial waste.
2.     Special hazardous waste also includes radioactive waste, explosive waste and E-waste.
3.     Biomedical waste, this includes clinical waste, and lastly,
4.     Municipal waste which also include household waste, commercial waste and demolition waste.

Now to explain what recycling is all about. Recycling is defined as a process of changing used material i.e. waste into new products to prevent the disposal of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for conventional disposal, and lower greenhouse gas emission as compared to virgin production. Recycling is a key component of modern waste reduction.

Recycling of a material will give rise to a fresh product of that material. Let’s properly look at some of the examples of recycling, glass bottles that are crushed, melted and remolded into bottles, many carton boxes are recovered from waste and resold as useful carton boxes, used office paper will be turned into new office paper, used foam polystyrene into new polystyrene.

The truth is that most waste materials could be recycled; there are some challenges to recycling of waste. To find buyers for the waste of one producer, who will consider the waste as a resource. Another is that, recycling can be difficult or too expensive compare to producing a new product from the raw material or other sources. Critics dispute the net economic and environmental benefits of recycling over it costs and they suggest that proponents of recycling often make matters worse and suffer from confirmation bias. Critics also argue that the costs and energy used in collection and transportation outweigh the costs and energy saved in production process, also that the jobs produced by the recycling industry can be a poor trade for the job lost in logging, miming and other industries associated with virgin production. Proponent of recycling disputes each of these claims, and the validity of arguments from both sides has led to enduring controversy.
