Daishan, a county in East China's Zhejiang province, has helped transformed the shipyard of local Japanese-invested Suneishi Group (Zhoushan) Shipbuilding Inc into a zero-waste one, local media reported recently.
"We chose Suneishi Group because we want more foreign companies to participate in our ecological conservation efforts and the company is a leading shipbuilding enterprise in Daishan," said Liu Xia, an official from the Daishan branch of the Zhoushan ecological environment bureau.
According to Jiro Sato, general manager of Suneishi Group (Zhoushan) Shipbuilding Inc, the Zhoushan company has been dedicated to becoming more environment-friendly. In recent years, it has invested more than 8 million yuan ($1.24 million) per year in environmental protection.
There are many examples in Suneishi Group's factory of its zero-waste efforts, including trash cans made from steel scrap.
Suneishi Group installed photovoltaic power generation devices on the roof of workshops and these devices can generate over 13 million kilowatt-hours of electricity per year, accounting for one third of the company's total consumption.
Suneishi Group also reduces the production of solid waste from the source. Since 2017, the company has used oil and sewage separators to separate waste oil. It has sold the waste oil and the wood from the outer packing of raw materials to other companies.
Currently, Suneishi Group can put nearly 2 million metric tons of waste oil and 10 million tons of waste wood into reuse.
