Physics:Home Energy Resources Unit

From HandWiki

The Home Energy Resources Unit or Home Energy Recovery Unit (HERU) is a prototype kitchen appliance which is claimed to use household waste to generate energy.[1]

Operation

Household waste, both organic and inorganic, is placed into a main chamber. Plastic and cardboard packaging as well as food waste can be inserted as fuel, and the waste does not need to be sorted or separated.[2] It then goes through an eight-hour cycle. The chamber containing the waste is heated to 100° celsius to evaporate water and remove oxygen. The temperature is then increased and pyrolysis takes place. Oxygen is then re-introduced to allow incineration of the pyrolised waste for water heating. After eight hours, a tankful of stored hot water is produced, and all plastic, cardboard and organic waste is reduced to gas and ash. The gas is then used in a domestic boiler, and the ash can be flushed safely into an ordinary sewage system. Any glass or metal waste is left in a clean state.[3][4]

History

The invention won a grant from the UK Government's Innovate UK Energy Game Changer Fund.[5] The technology won the 2017 Environment and Sustainability Group Prize of the Institution of Mechanical Engineers.[6]
