    RECYCLING WASTE IS TODAY’S NEED

    INTRODUCTION

    Recycling waste material reduces the use of natural resources. Recycling waste has become our need today. The broken material, scrap, and the material not in use are collected for recycling. Recycling waste material is the process that converts the non-usable degradable material into a usable one. Non-usable material available in any sector whether domestic, industrial, or commercial may create a storage problem: it occupies the space and hampers good housekeeping within the premises. All the material is often recycled whose properties do not change after recycling.

    In megacities, plenty of rubbish is produced. This rubbish is dumped outside the town at some designated place. At the dumping yards rubbish(biodegradable) is recycled for energy generation in the sort of methane. Tree waste, waste food, and vegetation are (biodegradable) can be used to produce compost manure. Plastic and other oil-based waste are degradable, however, they take a longer time to decompose.
    Waste materials shouldn’t be landfilled as they create environmental pollution. Waste like: Plastic, Paper, Glass, iron, and Aluminium are recyclable. Recycling does not change the properties of these materials

    ADVANTAGES OF RECYCLING
    Wastage of plastic, glass, paper, and iron is 100% recyclable. Recycling of this material has the following benefits:

    (1)A large amount of material and natural resources are saved, which are involved in the production of the new material from scratch
    (2) energy is saved by producing new material, recycling the waste material
    (3)The environment is protected as the use of natural resources is reduced.
    (4) Rivers and oceans are shielded from pollution.

    (1) RECYCLING OF GLASS
    Broken glass material and the glass material not in use are recycled alongside the material, Sio2(silicon dioxide) commonly known as sand, Caco3(calcium carbonate) commonly known as limestone, and Na2 co3(sodium carbonate) commonly known as soda ash. These materials are mixed together and heated into the refractory furnace at about 1500 degrees Centigrade to 17oo degrees Centigrade, which is the melting temperature range of sand. The melting of these materials forms the glass. This molten glass material is poured into the mold and various class articles are manufactured.

    Glass is manufactured in a batch process. Each batch is called a charge.
    This charge contains(sio2+ caco3+ na2 co3+ large amount of used broken glass material)., this charge contains the massive amount of used glass material that reduces the consumption of natural resources, sio2,caco3, and na2co3. This way it saves energy and protects the depletion of natural resources. The glass manufactured are of two types:

    (1) Soda-Lime glass(the common glass.)
    It’s durable however not thermal shock resistant.
    It is used for manufacturing household articles like bottles, jars, and other storage items, it’s used for windowpanes, door partitions, mirrors, and other decorative items.
    (2) (Borosilicate glass)
    Silica mixed with boron trioxide to forms the borosilicate glass that’s more thermal shock resistant. Beakers, flasks, fractionating columns, bur rest, and pi pates, and other laboratory items are manufactured from borosilicate glass, they are used in laboratories and industries.

    (2) RECYCLING OF PAPER

    Waste paper is used to recycle 100%. They’re chopped and mixed with water then heated to break them into small pieces to get the cellulose from them. The cellulose then dried and the paper is manufactured in a machine. Cellulose is the basic material that comes out from the plant and trees, that is used for paper making. Recycled paper nowadays is used in newspaper printing, book printing dairy making, and cardboard material for packing. This way recycling waste paper saves energy for us. Recycling of waste paper prevents deforestation and saves our ecological system. The following symbol is employed for 100% recycled paper.

    (3) RECYCLING OF IRON

    Iron scrap is collected and sent  to rolling mills or
    Foundries for recycling. In steel mills and foundries, these scrap materials are melted either in a cupola furnace or in an electric induction furnace and cast into billets. These billets are used at rolling mills and rolled into various cross-sections like round bars, angles, channels. These materials manufactured from iron scrap are used in building construction and in other domestic and commercial applications. This way the scrap iron is recycled and thus reduces the consumption of natural iron ores.

    (4) RECYCLING OF PLASTIC

    Plastic waste materials are available in various types. They’re mainly recycled for making packaging material for water, oil, shampoos, and other cosmetic liquid products. They’re also used for making containers and carboys. Plastic waste is available as PET(Polyethylene terephthalate), PP(Polypropylene), and HD PE(High-density polyethylene). These three plastic wastes are 100% recyclable. This plastic waste is collected, sorted out, crushed in machines, and washed for cleaning then converted into granules by extruder machines for recycling and manufacturing new articles. Plastic is derived from hydrocarbons, hence reducing the use of hydrocarbons can save our natural resources. Plastic recycling can reduce the consumption of fossil fuels. We should always change our lifestyle to use things precisely to reduce the use of natural resources to save our ecological system:

    (1)Reduce the generation of waste.
    (2)Reuse the material if it is in usable condition.
    (3)Recycle the material that is not in use, to get the usable one.
