CP Foods applies circular economy principles for sustainable egg production
Charoen Pokphand Foods Public Company Limited (CP Foods) has implemented circular economy-based programmes at its laying hen complexes in Thailand.
The effort will help CP Foods become a low carbon organisation that produces sustainable foods.
Somkid Wannalukkhee, senior vice president of egg business at CP Foods, said multiple initiatives ranging from resource efficiency project to waste reduction and green energy adoption have been implemented at the egg farms to ensure that food production and environmental sustainability can go hand in hand.
"In response to the company's low carbon organisation goal, our seven egg production sites in Chiang Mai, Phitsanulok, Nakhon Ratchasima, Roi Et, Udon Thani, Chanthaburi and Songkhla provinces adopted biogas technology to convert wastewater and animal manure into electricity used in the production processes," said Wannalukkhee.
CP Food's waste-to-green energy technology can help the layer complexes reduce electricity costs by 65-85%. Last year, the company had reduced 113,000 tonnes of CO2 equivalent of greenhouse gas emissions.
In post-biogas production, sludges are provided to local farmers for use as fertilisers in their farms. Post-production water can be recycled back to use within the farm, and some portions will be distributed to the farmers to make sure they have sufficient water resources during a drought.
Wannalukkhee added that water from post-biogas process contains essential nutrients for plants. In doing this, the farmers who received water from CP Foods' operations can enjoy better productivity.
Aside from promoting renewable energy, the company focuses on promoting reduction of food waste in the value chain to reduce the amount of landfill waste and disposal through variety of programmes.
CP Food's Ban Na Egg processing plant in Nakhon Nayok Province has converted about 1,000 tonnes of leftover eggshells from production processes into fertiliser, which are then provided to local farmers.
