STEPS TO ENSURE ENVIRONMENTAL SUSTAINABILITY
The use of chemicals in tanning of rawhides is reduced part by salt reduction and minimization the effluent. The company has decreased the usage of salt by 15% in 2016. The company further aims to reduce by 26% in 2017. SLW ensures to continuously improve processes and become more efficient
SLW has installed Water Treatment Plant, Lime Recycling Plant and soak water recycling system in an effort to stop the discharge of chemicals and harmful substances in water. The consumption of water has been reduced over the years from 400 liters/m2 to 205 liters/m2 and now further reducing to 169 liters/m2
SLW has successfully achieved 10% reduction in sulfide usage by making incremental changes in the process. It was enabled by efficient using of Lime Recycling Plant. About 95% of the solid waste is recovered from discharge using sludge filters. Chrome recovery plant is operational to eliminate chrome from water discharge.
The company has taken steps towards efficient utilization of energy. The old machines are periodically replaced to minimize the energy usage. Furthermore, SLW has shifted to renewable energy sources as environment friendly source of energy. It has installed solar thermal and solar PV Solutions to share the energy needs with electricity grid. The emission of CO2 is reduced by 300,000kg annually. The installations are further increased to reduce dependency on community power supply.

Water Conservation
Siddiq Leather Works has installed Water Treatment Plant, and Lime Recycling Plant and soak water recycling system in an effort to stop the discharge of chemicals and harmful substances in water. Furthermore, the consumption of water has been reduced over the years from 400 liters/m2 to 290 liters/m2 then to 205 liters/m2 and now further reducing to 169 liters/m2
Clean Energy Initiative
Energy sources are becoming one of the leading contributors to the global warming. There has been an increase in awareness in the leather industry and it has started to shift from conventional to renewable energy sources. Solar energy provides one of the important energy sources in Pakistan due to a large number of radiation hours. Siddiq Leather Works is the industry leader in introducing solar energy. It has installed solar thermal water heating system for increasing the temperature of water up to 60 C. The electricity requirements are mostly fulfilled by Installation of solar PV solutions during daytime.
