Archroma-Sustainability-Report-FY2018 - Page 57

Resource efficiency has been split into two separate topics; internal and external – see “Resource optimization”
below. This is to distinguish between our own footprint responsibility and our influence on the value chain.
Water discharge is dealt with under a separate topic due to its importance to environmental pollution.
External influence can only be an estimation based on sales data and relative performance of our systems
vs. an industry “standard”.
Energy is required for the production of specialty chemicals. The sources of energy are derived from the
combustion of fossil fuels to generate heat, and electricity to run the manufacturing equipment and
associated services, such as IT infrastructure and cooling apparatus.
Overall production in FY2018 increased by 6.7% to 479 thousand metric tons (kt) in comparison to
the previous reporting period.
The main fossil fuels are natural gas, diesel and heating oils, none of the production sites use coal as an
energy source. Electricity and, in some cases, steam is purchased from third parties.
In order to calculate the quantity of energy consumed in our production processes, amounts of fuel,
electricity and steam are converted into gigajoules of energy using conversion factors available in the GHG
protocol, as previously described in this report.
Energy efficiencies are closely monitored within the Environmental Management process, with annual
targets set according to forecasted production plans. Individual production processes are analyzed, with
respect to their energy requirements, and resultant process improvements devised in orer to reduce the
energy intensity, with associated annual targets which may be site and/or product specific.
The total amount of energy consumed by Archroma for FY2018 was 1 345 TJ, which represents a 9.8%
increase in comparison to FY2017. This equates to an average of 2.81 GJ per tonne of production, a 2.5%
increase over the previous reporting period.
Our medium term target for 2023 will be to reduce this by 15% to 2.39 GJ per ton of production.
