Chemical industry
The chemical industry is increasingly taking a more active approach to controlling its environmental impacts.
Faced with considerable regulations (Industrial Emissions Directive, Hazardous Substances in Water (RSDE) Analysis), chemical plant operators are working to better understanding what they discharge.
The discharges in this constantly evolving sector are so varied that an entire production range has emerged to meet the needs:
- Inorganic chemicals: industrial gases, dyes and pigments, basic inorganic chemicals, nitrogen products and fertilizers, explosives...
- Organic chemistry: petrochemicals, plastics, rubber, elastomers, polymers
- Detergents and industrial hygiene: detergents, soaps, disinfectants, insecticides, repellents...
- Specialty chemicals: adhesives, paints, varnishes, inks and sealants, essential oils...
Each operation is capable of generating effluents whose composition is specific to the processes used. This results in water that is often complex, which may be cost-prohibitive to outsource.
We help chemical professionals to bring their releases into compliance by treating them using technologies specific to the type of effluent:
Specific cases
