RECYCLING / SEGREGATION

Essential Objectives of Segregation of Solid Waste-
  • To separately store recyclable material for reuse.
  • To ensure that waste which can be processed for recovery of material and energy does not become co-mixed with undesirable elements.
  • To separately store hazardous waste for disposal in hazardous waste landfills or for appropriate processing.
  • To minimize the waste and ensure reduction in landfill space for final disposal.

Methods of Segregation:

Segregation or sorting can be carried out manually or through semi- mechanised and fully mechanized systems.

1.Manual sorting operation
   Manual sorting operation comprises of:
     1.1 Unloading the waste.
     1.2 Manually (with protective measures) spreading the waste.
     1.3 Hand picking (with protective measures) visually identifiable waste for reuse.
     1.4 Collecting and stockpiling the remaining waste.

2.Semi-mechanized sorting operation:
   Semi-mechanized sorting operations consists of:
     2.1 Unloading the waste (mechanized).
     2.2 Loading of waste on conveyor belts (mechanized).
     2.3 Hand picking of visually identifiable waste off the belt for reuse (manual).
     2.4 Collecting, stocking and reloading the remaining waste (mechanized).

3.Fully-mechanized sorting operation:
   Fully-mechanized sorting operations comprise of:
     3.1 Unloading of waste.
     3.2 Size reduction of waste through shredders and crushers.
     3.3 Size separation of waste using screening devices.
     3.4 Density separation of waste.
     3.5 Magnetic separation of waste.
     3.6 Compaction of waste through balers/crushers.
     3.7 Reloading of waste .


Recycling Waste


With the increasing human population the needs for the people also increases. But the point of concern is that are there enough natural resources to service all your needs. What if these resources finish, this is one thing we need to ponder upon. We need to start recycling waste to converse our natural resources. Recycling is simply the process of reusing the items from which utility can still be derived. It is important to recycle waste so that you can at least converse some of our natural resources for our generations to come.

Many products such as paper, cardboards, and cups come from trees. In fact trees are our natural assets, you can converse trees by recycling the paper products we can minimize the number of trees cut down a year. This is one form of waste recycling. One should understand and know the importance of recycling waste materials. One simple benefit of recycling is it saves our resources. It will be wise to reuse metal item as metal reserves may be depleting. You can sold your wore out metal items for recycling. As mentioned earlier, recycling of waste papers can save our forests.

Recycling waste not only save our natural resources but also help save energy. By simply recycling an item or making a basic fix to it, we can we save all the energy that would have been consumed in the process of making it. The same example can be taken with plastic items. A large amount of energy can be saved by simply reusing the plastic items. To recycle waste is to simply reduce pollution. By recycling plastic material we can reduce air pollution as well as water pollution. Plastic factories produced large amount of smoke when producing plastic material at the same time if we don’t have proper waste disposal system those waste emissions will cause water pollution. Recycling waste in a way helps reduce pollution.

Recycling requires much less energy and therefore helps to preserve natural resources. One needs to know the importance of recycling at the same time being earth friendly can help our planet a better place to live in.
