Purac has won unanimous praise and trust from the clients with its stable and reliable anaerobic technology and many years of successful experience in kitchen waste treatment. After the implementation of the garbage classification policy, Purac has successively won contracts for more than twenty household kitchen waste anaerobic treatment projects, including Xiong'an, Shanghai, Wuxi, Nanjing, Tianjin, Chongqing etc.

In response to the characteristics of high water and high organic matter content in kitchen waste, Purac has launched a full-process kitchen waste treatment solution, from raw material reception to the discharge of water to meet standards. The organic matter in kitchen waste is treated anaerobically to produce biogas, which is used for heating, power generation, or purification. The entire system is integrated by three mature processes: EFWA pre-treatment, ANAMET anaerobic digestion, and SDN-N water treatment. The biggest feature of the system, compared with the conventional wet anaerobic treatment process, is that there is no need to add water sources other than the moisture carried by the materials.

In addition to the wet anaerobic process, Purac can also provide dry fermentation and dry-wet combined anaerobic process according to the different garbage characteristics of different regions.
