To enable companies to save the costs of organic waste treatment, a Chinese startup offers a connected digester that produces reusable energy for the company.

Every year, the Middle Kingdom alone produced 430 million tonnes of organic waste, costing nearly 200 billion Yuan (a little more than $29.5 billion). Enwise wants to revolutionize the waste management sector by creating a smart digester addressed to businesses (supermarkets, restaurants, company canteens...). The "IBIS" digester uses sensors so that companies can monitor and analyze by themselves 24 hours a day the evolution of the treatment of their waste and the equipment performance. This service is beneficial to the company for two reasons: organic waste is processed directly on-site, saving the processing costs of an external company, and the treatment allows the creation of fertilizers which can either be offered to partners such as farmers, or give enough energy to supply the company with hot water or electricity. The whole value chain is optimized and thus preserves the environment. Auchan China uses the "IBIS" solution, which has reduced its organic waste production by 85%. This solution is particularly interesting for the Chinese government, which last year announced the main orientations of its economic plan over 5 years, towards sustainable development and green energy. China will need to optimize the management and treatment of its waste to meet this plan and the country has already invested 250 billion Yuan ($37 billion) in this direction.
