PORTALJABAR, BANDUNG CITY - The Chinese community of Bandung City has innovated waste processing using the Nawasena tool. Collaborating with a number of mechanical experts, this community created a machine for processing residual and non-residual waste without having to sort it first.

The way this tool works is that organic waste and plastic waste or residue are directly put into the chopper. So that the waste becomes small pieces.

Then, the chopped waste is given tapioca flour and mixed with a mixture of an addictive substance such as fish food powder. After being put into another tool, it becomes a briquette.

These briquettes have been tested as fuel for a specially made stove with a booster using fresh water.

From the results of testing fuel for cooking, the resulting fire has no smell. After that, the processed waste is molded into briquettes. With these waste briquettes you can boil water in just 3 minutes.

Nawasena Machine Technician Yaya Suhaya said, to date, there are already several other areas that use this waste processing machine. For example, in Indramayu, which reportedly has ordered 6 sets of this tool.

Apart from the residual waste processing machine, Yaya also explained the Biomas stove machine to use wood and leaf waste as fuel. He said that many factories in Indramayu and others already use these stoves.

Chairman of the Bandung City Tolerance Ambassador, Tan Tjong Boe, said that processing waste into briquettes is economically and environmentally beneficial. It is also an alternative to the waste problem in Bandung City.

"We named this machine Nawasena, and it can process 3 tons of organic waste and residue per 7 hours," said Tan.
