Majority of the plastic and synthetic rubbers are not biodegradable. So if they are discharged as waste without recycling, then they accumulate in nature and cause lots of problems.  Accumulation of these materials at a stage, block the sewerage lines stopping the flow of waste water that results in water logging on roads upon rainfall.

 Clearly, it hampers the environmental balance. Similarly, a significant part of waste is not managed properly and discharged into river or lakes directly. If they are deposited long time in this way, water depth will be reduced and will cause navigability problem. Moreover, if they are discharged on soil, soil fertility will decrease. Waste plastic or rubber sometimes enters into animal body such as cattle, sheep or goat when those animals take grass in field, and they can accumulate in animal flesh and fat. In fact, the discharged plastic in water bodies may contaminate fish flesh. Finally when we take meat or fish, those accumulated plastic and rubber enter into human body and may cause diseases like cancer. So it is clear that, if plastics and rubbers are not managed properly, they can pollute the environment severely and may lead to environmental imbalance.

Therefore, we have to reuse and recycle plastic and rubber again and again and also we have to make people aware in this regard. If they become unsuitable for use, we have to collect them and collected plastics and rubbers can be sold as well. If we do so, our environment will be conserved as well. In case if we do not have opportunity to sell it, we have to send it to the municipal authority managing solid waste.
