Encap: waste to value added products

In spite of the ever-growing electronic revolution, the demand for paper products is still increasing. Along with this demand comes a lot of waste. According to CleanUp.org.au, Australians send 1.9 million tonnes of paper to landfills each year, most of which could be recycled. ENCAP Continue reading →
