Waste generated during chemical manufacture is directly related to the type of chemical synthesis employed.
The more reactive the chemical process, the higher the chemical yields tend to be and the lower the generated
resultant waste. The less small packed raw materials are used the lower the generated resultant waste will
be. Wherever possible waste is avoided, recovered and reused as a function of improving process efficiencies.
However, in some instances, waste, both hazardous and non-hazardous, is generated which cannot be
recovered and reused and has to be disposed of in a suitable manner, as has been reported previously.
The hazardous classification of waste, and resultant disposal methods, is made according to the specific
national regulations governing the production site. There was no significant transboundary transport
of hazardous waste.
By using the “atom economy” within the 12 “Principles of Green Chemistry” (see page 56), processes are
being continually optimized to reduce waste and increase yields. This is normally achieved by modifying
production processes to the best available chemical manufacturing, and often these improvements are the
result of internal projects driven from our chemical process technology centers of excellence.
Our total solid waste generated in FY2020 was 18.4 Ktons. This represents an intensity of 46.8 kg per ton
Our medium term target for 2023 is to reduce the waste intensity to 31 kg per ton of production.
The total waste generated during FY2020 was 18 439 metric tons, of which 59 % (10 906 metric tons)
was classified as hazardous.

Of the hazardous waste, 59% (6 486 metric tons) was disposed by incineration. An amount of hazardous
waste, 18% (2 055 metric tons) was disposed in appropriately licensed landfill sites.
Of the total waste 40% (7 367 metric tons) was disposed by incineration, 38% (6 958 metric tons)
was disposed to landfill, and 22% (4 114 metric tons) reused, recovered or recycled.
The major driver of the increase was the addition of the newly acquired Ankleshwar plant in India.

Non hazardous waste
Waste management forms a part of the overall Archroma environmental safety management process.
The majority of waste is generated as a result of the intrinsic chemical manufacturing processes and their
specific process yields, raw material packaging materials and residues from on-site effluent treatment plants.
Wherever possible waste is analyzed to assess whether it can be recovered and/or reused and recycled.
Solid/semi-solid waste generation, including any waste generated from off-specification production, and
disposal is an ongoing topic of concern. Hazardous substances classification and management of adequate
disposal routes is of critical concern.
