II. Harmonic filters installed power house and hot air • Jet cleaning system in filter press to reduce the water
generator (CFHAG) detune filters consumption
III. Auto power factor controller panel detune filter
At the Innovation Centre, Pune:
IV. 160 KVA uninterrupted power supply
• Installed 100 KW rooftop solar power panels. Currently,
• Ongoing projects include: the energy production stands at 450 Kwh/day and
I. CFHAG bio fuel trial completed and continuous contributes to 20% of the total energy consumption.
feeding will start after feeding system This installation correlates to 3,000 tonnes of carbon
upgradation
emission abatement which could benefit around 5,000
II. Solar project roof top is in the commercial trees planted per annum
ordering stage
• Having begun in January 2022, 31 tonnes of CO
III. Rainwater harvested water reused to garden as 2
well as in utilities reduction is achieved through electricity saving due
to planned shutdown (18.8 tonnes) and solar system
IV. Replacement of existing filter plates with new
designs to reduce the water consumption (12.2 tonnes)
V. SOP for filter press operator to reduce the wash (ii) The steps taken by the Company for utilising
water consumption alternate sources of energy:
VI. Water inlet from bottom and outlet from top • Consumed alternate fuels: shredded plastics, spent
changed on the filter press to reduce the water resin, spent oil, spent grease, TDI Tar at Mithapur
consumption
VII. Exploring the utilisation of sulfuric acid for which • Solar rooftop energy project is in final stage of
a detailed investigation is underway to obtain commercial discussion and is expected to be
high quality acid for our utilisation completed in FY 2022-23
