Parry’s approach to waste management starts with exploring areas for reducing waste followed by reusing and recycling waste. Since microalgae production is an organic process, the process waste generated is non-hazardous and has high nutritive and calorific value. Reduction in waste quantity protects precious resources, reduces emissions and prevents land pollution and contamination. By utilizing the pond sludge as organic compost and selling of process residue salts as animal feed, we are able to generate revenue from salvaged resources.
We follow the 4 R’s to manage waste sustainably:
Reduce - We consciously avoid single-use of resources and use our resources responsibly
Reuse - We reuse resources wherever possible. eg. Pond water is reused after microalgae harvest, spillages in microalgae processing can be collected and used as animal feed.
Reprocess - Our waste is reprocessed to recover salts. These salts can be used in animal nutrition.
Recycle - Process waste is recycled as organic compost and as animal feed. We are conducting experiments to use pond sludge as biomass briquettes for boilers.
Apart from the following 4 principles, we motivate all our employees and stakeholders to mindfully monitor the generation, collection, storage, reuse, recycle and disposal of waste. We also promote and support educational and awareness programs around waste management.
We strongly believe that waste is managed responsibly today, can create a sustainable and greener tomorrow.
