A proprietary process in which a deceased person’s body is immersed in a solution of water and potassium hydroxide, heated to 180ºC and pressurised for 3 hours; all that remains is a brownish semi-liquid and the bones.
Bosses are also planning a grisly procedure called resomation which J involves placing bodies in silk bags and submerging them in a 160C (320F) alkaline solution to dissolve them.
Six states in the US have passed laws to allow resomation and talks are ongoing to make it legal in Britain.
Developed by a firm in Scotland, resomation is a high-temperature water and chemical treatment that dissolves mortal remains, and the process is as quick as traditional flame cremations, but without the environmentally harmful chemical emissions.
Mr Sullivan, who is the founder of Resomation Ltd, said: "It uses the same bio-chemistry as in natural decomposition when a body is buried, but it is quicker and much more environmentally friendly.
