The excellent project of  deal with sludge
  The project adopts the technology of "deep dewatering of sludge + low temperature drying + coordinated incineration", and uses the existing cement clinker production line for harmless disposal of sludge, which has low cost, strong stability, reduced land occupation and maximized resource utilization It embodies the principle of “reduce, reuse, and recycle” of circular economy, which is in line with the development model of circular economy.
      This project is a key project of Xi'an City's “Global Water Treatment and Green Water Rejuvenation”, which has attracted great attention from Shaanxi Province, Xi'an Municipal Government and BBMG. BBMG Mangrove Co., Ltd. started from focusing on improving the sludge disposal capacity and solving the problem of sludge disposal, using waste heat from cement kiln waste gas as the heat source for sludge drying, and adopting low-temperature drying technology to prepare alternative fuels to save energy and improve the harmlessness of sludge. At the same time of disposal capacity, it has realized 4% fuel substitution by cement companies, creating a domestic precedent and becoming a new bright spot of BBMG environmental protection.
     The project, which lasted for more than 3 months, has been formally completed and put into production. The annual disposal of sludge can reach 264,000 tons, which will effectively solve the problem of sludge disposal in Xi’an, and realize the sludge "eat dry and squeeze, turn waste into treasure". , The goal of “win-win” economic and environmental benefits is the current domestic leading cement kiln co-processing sludge project, which has been highly affirmed by the Shaanxi Provincial Department of Construction and the Xi'an Municipal Government
