Abatement and Waste Treatment: Summary and Further Reading

There are a number of abatement and waste treatment options available to operators and a number of variables should be taken into consideration including pollutants, local legislation/limits and process conditions. Best Available Techniques should be used to abate any fugitive emissions and waste to landfill should be minimised. If feasible (and if positive benefit is determined from life cycle assessment), recovery and recycling of solvents should be carried out. Precious metals can also be recovered and reformulated, and other catalysts/non-reactives may be recyclable. It is also important to consider the upstream operation and avoid depending on end of pipe solutions. Good route design will minimise reliance on end of pipe solutions and effort should be made to develop processes that have minimal environmental impact.
