What is waste management?
First of all, there are many varieties of waste: municipal (household, business, and demolition waste), unsafe (industrial), biomedical, electronic (e-waste), radioactive, etc. Waste management includes the collection, transport, valorization, and disposal of those waste. Generally, it includes any activity concerned within the organization of waste management from production to final treatment.
The main principles of waste management are:
- Waste hierarchy, relating the “3Rs rule” reduce, Reuse and Recycle, and reduction is the foremost fascinating goal.
- Extended producer responsibility, adding all the environmental costs to the value of a product, as well as end-of-life disposal.
- The polluter pays principle, requiring that a waste generator pays for the suitable disposal of the waste.
General waste management techniques
Landfill – It involves having the waste buried off in empty, deserted locations outside town. The dumped waste is created to endure compression to enhance the density and make the filling stable. It’s later coated to discourage vermin growth. A gas extraction system is usually put in to exact the gas (arising out of decomposition) through a burrow pit.
Incineration – Waste is exposed to high temperatures to trigger combustion and ultimately reduced to ash, gas, and warmth energy. unhealthful wastes from the business area unit thermally treated in a chamber and boiler to extract energy. This methodology is beneficial wherever land is scarce. chemical change and transmutation strategies involve heating waste briefly and offering oxygen at high temperatures inside a controlled and sealed vessel.
Recycling – Paper, plastic, PVC, and different homogenized products can be recycled to put them in use in new garb. This conjointly rids the environment of non-biodegradable, chemical wastes that considerably disturb the ecological balance.
Biological reprocessing – Wastes of organic origin area unit created to bear biological decomposition and re-used as compost or mulch for agriculture and landscaping. Gas collected is used for electricity generation.
Waste Reduction and avoidance – the strain is on the increased use of second-hand merchandise, repaired merchandise, and reducing the utilization of complicated disposable things to keep a tab on waste generation in abundance.
Recycling Solutions – employment could be a superlative way to make the most accumulated waste by chemically treating it to create it suited re-use. recycling equipment makes the waste process methodology efficient and cost-efficient.
There are various other challenges like establishing a proper awareness system, developing policies related to the throwing of waste, and many others. Despite their inability to properly manage wastes, the majority of municipal officials consider waste as “wealth” when approached by private partners. There are some ventures like Clean India Ventures who are helping to make the environment better with their organic waste converter processor which has been designed to reduce and recycle organic waste and convert it into organic compost and liquid fuel. They have machines for processing kitchen waste, temple waste, Food waste into organic compost.
