VietNamNet Bridge - Input material sources and the encouragement by the state both have encouraged more and more businesses to invest in waste recycling projects.

Waste paper is cut into small pieces, mixed with some ingredients, frozen, defrosted and dried.

Cutting waste water into small pieces, mixing the pieces with some ingredients, freezing the mixture and then defrosting and drying it are all done by students from the HCM City Industry University. They create a porous material which can absorb the volume of oil which is 17 times higher than its weight.

The finding is hoped to help settle oil slicks, which causes millions of deaths to sea creatures every year.

A report showed that about 20 million tons of solid waste was discharged in urban areas in 2015, most of which were on open cast dumping grounds or were buried in unreasonable way, which led to water and soil pollution.

However, in Vietnam, recycling waste remains an underdeveloped industry.

The government has recently laid down a series of policies to encourage the investment in waste treatment projects.

It decided that 85 percent of waste must be used by 2020. The Prime Minister has asked manufacturers to recall and treat waste electronics. Meanwhile, the enterprises operating in the field of environmental protection begin enjoying tax preferences from 2016.

Many large-scale waste treatment plants have been set up in recent years. These include the Khanh Son Solid Waste Treatment Plant in Da Nang. With the capacity of 200 tons of waste a day, Khanh Son can treat many different kinds of waste in accordance with different processes. 

Plastic things can be used to make PO, RO and FO oil, while organic garbage is used to make biological charcoal. Meanwhile, glass bottles and rocks will be recycled to become additives used in construction.

In HCM City, people put high hopes on the $520 million project which treats waste in accordance with plasma technology developed by Trisun Green Energy.

The investor said the project, once operational, would be able to treat 2,000 tons of domestic waste a day to generate electricity and make building materials.

A question has been raised about whether recycled products would be accepted. The answer is ‘yes, but it will take time’.

When asked about the consumption, Luu Van Trang, director of Karta Paper Company, said her business churns out 14,000 square meters of recycled paper. The paper packaging industry was once thought saturated. However, the new production tendency can bring profit of 5-10 percent.

A scientist said that one thermal power plant generates a volume of ash big enough to produce 1 billion unburned bricks a year.
