Plastic waste is a growing problem for many and for some it is an opportunity. Here is a small company in Ghana which has invented simple technique to convert plastic waste into pavement blocks and other building materials.
NELPLAST Ghana Limited, a manufacturer of plastic products, uses plastic waste to produce pavement blocks and other building materials. The company made use of all forms of poly waste products except PVC pipes, mixed with river sand, to produce solid pavement blocks. With this invention, the company aims to kill two birds with single stone – menace of plastic waste and inadequate infrastructure facilities of the nation.
According to the company, the end product is made up of 70 per cent plastic and 30 per cent sand without any cement, and is 800 per cent stronger than the ordinary pavement blocks. The company has developed a technology that melts plastic without releasing harmful chemicals.
However, the company currently has an existing setup for the production of these new products, but needs a Hydraulic Press, which is a machine for compressing and moulding the heated plastic mix, to enhance its quality and scale up production.
