Making a new product requires a lot of raw materials which must be extracted from the earth; the best way to reduce waste is not to create it. As a result, we need to reuse the products which we can cloth bags to stop plastic, reuse containers, donate things which you don't need and follow recycling Policies. These are the most effective ways you can save natural resources, protect the environment and save money.

Wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water. Through the treatment of wastewater, the amount of waste that is usually released into the environment is reduced thus improving environment's health. Common ways to treat wastewater include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.

Agricultural waste is produced by various agricultural operations. It includes manure and other wastes from farms, poultry houses and slaughterhouses, harvest waste, fertilizer run- off from fields, pesticides that enter into water, air or soil, and silt drained from fields. Agricultural waste management system is a planned system in which all necessary components are installed and managed to control and use by-products of agricultural production. Vermicomposting is effective method as it contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner.

Hazardous waste is that has substantial or potential threats to public health or the environment. Hazardous wastes are materials that are known or tested to exhibit one or more of the following hazardous traits: Ignitability, Reactivity, and Corrosive. Hazardous materials management chemists are an integral part of teams responsible for detecting and identifying chemical pollutants in the air, water, and soil. Chemists also help design techniques that reduce pollution and reduce problems caused by hazardous waste.

Electronic waste is sent to landfills, which releases materials such as lead, mercury, or cadmium into the soil, groundwater, and atmosphere, which effects the environment. Recycling e-waste can significantly decrease the demand for mining heavy metals and reduce the greenhouse gas emissions from manufacturing virgin materials. Recycled rubber is produced from replaced tires through a straightforward process. There are two main ways ambient shredding and cryogenic process.

Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products.  Plastics that can be recycled are first sorted, shredded and rid of impurities like paper. The shreds are then melted and formed into pellets, which can be made into other products. Pulp and paper industry are a major contributor in terms of air and water pollution. Recycling of paper not only saves tree and minimizes pollution, but also reduces the waste problem by utilizing waste materials like used paper.

Chemical waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations. Recycling chemical waste can make less air, water, and soil pollution. Chemical recycling produces high quality end products and decreases dependency on imports and lowers carbon footprint of products. Improperly managed chemical waste may pollute and contaminate water streams.

After all, used oil from one oil change can contaminate one million gallons of fresh water. Petrochemicals are chemicals which are acquired from oil; and these things fuse regular and moreover inorganic chemicals. In the petrochemical business, the wastewater may contain high measures of oil which are released in the wastewater in the midst of a couple of strategies. Waste water treatment in oil refineries is a mind boggling process; Used oil can be developed into lubricants, processed into fuel oils, and used as raw substances for the Refining and Petrochemical Industries.

From the most basic environmental point of view, all materials are worth recycling, because this reduces the need for energy-intensive mining and smelting of virgin materials. Reduce, Reuse, and Recycle. Reducing is cutting back on the amount of trash we make, reusing is finding a new way to use trash so that we don't have to throw it out, and recycling is using trash to remake new goods that can be sold again.
