Honda Siel Power Products ,Ltd. (HSPP) manufactures and sells power products in India. To prevent fluctuations in manufacturing output due to sudden power outages of commercial electricity sources, and to fight skyrocketing fuel prices for backup electricity, the firm has introduced high-performance cogeneration systems that operate at costs and environmental performance similar to natural gas-powered generators. This strategy has helped stabilize daily output and reduce per-unit CO2 emissions during manufacturing by 30%.

Surplus heat from cogeneration systems is also used in boilers for coating equipment, further reducing energy costs. The firm is now studying how to utilize the remaining 20% of waste heat for air-conditioning systems.

Honda Cars Philippines Inc. (HCPI), the manufacturer and sales company of Honda vehicles in the Philippines, built worm-composting facilities in April 2011 to process green waste from gardens on the factory grounds. With a capacity of 10 cubic meters, it includes a water supply device to control moisture and a shredder to break the waste down into smaller pieces and create compost more efficiently. African night crawlers (worms) are used to further accelerate the composting process. Compost produced in the unit is used as organic fertilizer for greenery on the premises, and also for tree planting and other CSR activities offsite. The firm expects these facilities will help it reduce the waste it sends to the landfill to zero.
