The objectives of the Minimizing Formation and Releases of Unintentionally Produced Persistent Organic Pollutants Project for China are to demonstrate the result of Best Available Technologies and Best Environmental Practices (BAT/BEP) adoption in four selected non-wood pulp mills and to strengthen environmental monitoring and enforcement in four participating provinces.
Negative measures include: air pollution, dust, noise pollution, soil erosion, water pollution, waste management, and ecology. Mitigation measures include: a) Combined Heat and Power (CHP) production and power generation by waste heat can not only to control cost but can also meet the whole or part of the electricity and gas demand, and consequently make a good use of energy; b) adequate thermal insulation materials should be applied, where needed, to the equipment or pipes to reduce heat loss; c) daylighting should be put to good use during plant design in order to economize lighting power; d) gauges, meters and other automatic instruments can be installed in the process flow to control the consumption of electricity and gas and provide a favorable condition for practicing energy conservation management in the plant.
Stocks or materials should be conveyed by gravity, instead of pumping, to save electric power; e) advanced wet stockpiling and wet cleaning of bagasse may help minimize soluble impurities, so that the alkali consumption can be reduced in the cooking process and, as a result, less energy is consumed; and f) enclosed medium-concentration screening machines and technologies can be employed to save power and water.
