Project Horana Go Greener
Our state-of-the-art manufacturing facility in Horana is home to some of the country’s best loved brands including local favourites like Sunlight, Lifebuoy and Signal. Thanks to Project Horana Go Greener, our facility has been designed to tackle climate change by reducing our consumption of natural resources through rainwater harvesting, waste footprint reduction, waste heat recovery, greenhouse gas reduction and the usage of renewable energy.
Here’s how we act on climate change:
1. Rainwater harvesting: Our Horana factory belongs to the low country wet agricultural zone, which experiences an annual rainfall of 3500 mm. We commenced rainwater harvesting in a small scale in end 2017; and with continuous improvements, have scaled up to save 20,000 tonnes of rainwater a year. Approximately 70% of our factory roof areas are utilised to collect rainwater which is flown through underground pipes to storage tanks. The harvested water is further treated through an ultra-filtration or Reverse Osmosis (RO) process before being used for utility purposes like cleaning and washing. Harvesting rainwater has also helped us reduce our water sourcing requirements from the Kalu Ganga through the BOI treatment plant, minimising our electricity consumption used to abstract water.
2. Recovering heat energy and condensate: We introduced a technology called a ‘compressor waste heat recovery system’ that recovers and reuses 50% of the heat energy that goes to waste every year during our operations. This heat energy is equal to the energy used by 350 households a year. We have saved 500 tonnes of steam energy per annum thanks to this initiative.
3. Renewable energy and greenhouse gases: We meet 95% of our steam requirements through biomass fuel. This renewable source of energy has helped us reduce our Co2 emissions by 84% of the last 8 years. Our factory is also equipped with solar streetlights, taking us one step closer to becoming carbon positive by 2030, which means that 100% of our energy will come from renewable sources.
