Plastics are made up of long chain molecules called polymers. Various types of polymers can be made from hydrocarbons derived from coal, natural gas, oil and organic oils which are transformed into materials with desirable properties. Plastic that can be readily recycled are Thermoplastics which means they will soften when heated. Thermoplastics are light, durable, mouldable, hygienic and economic, making them suitable for a wide variety of applications and can be repeatedly reformed into new products.
Why recycle plastics?
Recycle plastics has many benefits. It contributes to energy saving and the reduction of greenhouse gas emissions. It also saves non-renewable sources like oil and gas. In addition to that, recycle provides livelihood for millions of people and families in developing countries, either in the form of formal employment or informal economic activities.
Although there is a rapid growth in plastics consumption in the developing world, but, plastics consumption per capita in developing countries is much lower than in the industrialized countries. However, there is a much wider scope for recycling in developing countries like Bangladesh due to several factors:
|In developing countries like Bangladesh, the scope for recycling of plastics in growing as the amount of consumption increases. Collecting, sorting and recycling plastic waste becomes a viable activity.|
|Labor costs are lower.|
|In many countries there is an existing culture of reuse and recycling. With the associated system of collection, sorting, cleaning and reuse of water or used materials.|
|There is often a informal sector which is ideally suited of taking on small-scale recycling activities.|
|Collection & Transportation cost are often lower.|
|Low cost raw materials give an edge in the competitive manufacturing world.|
|Innovative use of scrap machinery often leads to low entry costs for processing or manufacture.|
