All You Need To Know About Waste Management
Waste generation has been a part of human lifestyle since ancient times. Humankind realized a direct relation between the waste production and dangerous health hazards and therefore derived methods from dealing with it. Earlier, the procedures followed was digging in deep holes in the sand and burying all the faecal matter. As modernization seeped in, there were new inventions, some eco-friendly and some not. Therefore, alternative methods were looked for, and that’s how professional waste management became an elaborate practice. The scope of its work covers collection, recycle and disposal of waste using innovative technologies. One of the best waste management company in Australia is Cleartech Waste Management Pty Ltd. As per the report shared in www.ecowatch.com, nations world over are extensively working to reduce waste, recycle it and reuse it in the eco-friendliest way.
Let us first review categorization of waste generated by mankind. Solid waste which may include urban waste, industrial waste, biomedical waste, radioactive hazardous waste and agricultural waste. Liquid waste which are chemical and impure liquids generated as a result of washing, flushing and other manufacturing procedures. Gaseous waste, which are prime reasons of air pollution generally excreted by petroleum and fossil burning. Bifurcation based upon sources of waste generation include municipal waste from households and other commercial setups. Medical waste which is highly infectious and hazardous, generated from hospitals and clinics. Agricultural waste produced out of various processes like livestock breeding, seasonal cutting of crop, damages to crop due to pest or diseases etc. Construction and demolition waste and electronic waste.
Methods of disposal management include:
1. Landfills: The most traditionally followed one includes burying of the collected garbage into the land. These locations are generally located away from the populated area, and special techniques are used to reduce the odour and danger. This method has been discouraged in current times considering the air and water contamination it causes. The strong presence of harmful gas like methane in and around the area causes serious air pollution.
2. Combustion: A procedure where the solid waste is burnt at a very high temperature leaving back minimal residue. This reduces the volume of waste.
3. Recycling: It is a procedure to convert the discarded item into new product or source of energy like electricity, cooking fuel, hence restricting mankind to explore the precious non-renewable energy resources.
4. Plasma gasification: This uses a chamber wherein waste is dumped; the plasma is lightened up to produce a high temperature of 12600 degree which breaks the molecular bond between the waste material and converts the solid and liquid waste into gaseous form.
5. Compositing: A natural way of managing waste which is also encouraged to be adopted personally at households. This process converts organic waste into nutritious manure for plants. The process involves microbes to decompose the waste.
6. Waste to energy: A innovative way to convert non-recyclable waste into a renewal energy like electricity, fuel which can be reused again. The biggest advantage of this process is it reduces carbon emissions, as a result, preserves the environment.
As rightly said that precaution is better than cure. Encouraging people to renovate and recycle old belongings into something usable instead of dumping them and buying new ones’ is the way to go ahead.
