Division BAT 22 In order to reduce the quantity of waste sent for disposal, BAT is to use the techniques (a) and (b) and one or both of the techniques (c) and (d) given below.

United Kingdom

Technique		Description
(a)	Waste management plan	A waste management plan is part of the EMS (see BAT 1) and is a set of measures aiming to: 1) minimise the generation of waste, 2) optimise the reuse, regeneration and/or recycling of waste and/or the recovery of energy from waste, and 3) ensure the proper disposal of waste.
(b)	Monitoring of waste quantities	Annual recording of waste quantities generated for each type of waste. The solvent content in the waste is determined periodically (at least once every year) by analysis or calculation.
(c)	Recovery/recycling of solvents	Techniques may include: recovering/recycling solvents from liquid waste by filtration or distillation on site or off site; recovering/recycling the solvent content of wipes by gravitational draining, wringing or centrifugation.
(d)	Waste-stream-specific techniques	Techniques may include: reducing the water content of the waste, e.g. by using a filter press for the sludge treatment; reducing the sludge and waste solvent generated, e.g. by reducing the number of cleaning cycles (see BAT 9); using reusable containers, reusing the containers for other purposes, or recycling the container material; sending the spent limestone generated from dry scrubbing to a lime or cement kiln.
