Solid Waste Management

Recycling

Recycling is a process to change waste materials into new products to prevent the wastage of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the waste disposal. Recycling is an useful key component of modern waste reduction system.

Solid Waste Recycling

Recyclable solid waste materials include different types of solid materials such as glass, paper, metal, plastic, polyeteline, textiles etc. Although similar in effect, the reuse or the composting of biodegradable (organic) wastes such as food or garden waste is not typically considered recycling.

Textile Waste Recycling

Different types of solid waste can be found from textile and garments industries. Piece of cloths, unused yarn, broken buttons and other utilities are among them. These things can not be used in garments making but they can be used in other ways. As for example, Garments Cotton is the type of cotton which is made by the waste fabrics and yarns torne or cut in small length.

Plastic Recyclin

gPlastic is a such element that does not reacts with natural components anyway so that that harms much to the environment. It reduces soil fartility, obstacles the water flow, even sometimes increases deseases. So recycling plastic materials is the only way to reduce the pollution created by it.

Plastic Recycling Process

The process of recycling plastics as Polyethylene Terephthalate(PET), Polyvinyl Chloride(PVC), Polypropiline(PP), Polystyrene(PP) and others are:

Collecting Washing Melting Refining Producing recycled product

PET is known as the food grade plastic. So it needs to be sanitized and non harmful for human use after recycling.

There are several types of metals we use in our daily life. Among them we use iron (steel), aluminium, coppar mostly. Here the recycling process of aluminium is given.

Glass recycling is the process of turning waste glass into usable products. Glass waste should be separated by chemical composition, depending on the end use and local processing capabilities, might also have to be separated into different colors. Many recyclers collect different colors of glass separately since glass retains its color after recycling. Glass is a brittle substance and in broken state it is so sharp to cut human or animel skin.

Paper Recycling

After use, the waste papers such as Newspspers, Books, Writing pads, Packing papers etc are collected and others stored. Then they are taken to the recycling industries and then they are passed through several processes to make them re useable in same or different ways.The things which can be made by recycled papers are: Newsprint Papers Envelops Paper Bags Boxes Hard boards
