Compared to wind and solar renewable energy, the production of biomass energy is more closely related to human activities. The Indonesian National Research and Innovation Agency (BRIN) utilizes wastewater from soybean-based tofu productions to produce biomass, providing renewable energy for cooking purpose. And the researcher introduced the wastewater treatment mechanisms to mitigate the waste pollution problems.
Neni Sintawardani, a senior researcher at the Research Center for Environmental and Clean Technology (PRLTB) under the National Research and Innovation Agency (BRIN) and the main driver of the project, stated in an interview with RECCESSARY that the tofu manufacturing process produces a large amount of waste, especially wastewater, which causes serious pollution to the surrounding areas. Because this type of waste is rich in nutrients and low of pH, it can easily lead to excessive algae growth, resulting the oxygen levels in the water decreases, making it unsuitable for other organisms to grow.
