The solution

A new concept for waste heat recovery for temperatures of between 200 and 1.000°C, with low capital and operating expenses, based on the implementation of ceramic materials inside a container named Eco-Stock. Well adapted to small and medium industries, it comprises of a 20 foot, 30 tonne container with a capacity from 1 to 3 MWh th per cycle. Cycles run from 30 min to 8 hours. Temperature from ambient to 1000°C. Thermal loss from just 5 to 8% per day.
