Ben Upham, over at "Triple Pundit" has written an article entitled, "Body-to-Bone ("B2B") Sector Goes Green with Bio-Cremation" that looks at a potentially greener way of cremating bodily remains called "Bio-Cremation", which emits one tenth the carbon dioxide of traditional cremation, according to the company.
"In traditional cremation, the corpse is incinerated in a natural-gas fueled combustion chamber, releasing the equivalent of 880 pounds of CO2 into the air â€“ equivalent to the environmental impact of a 500-mile car trip, according to Reuters.
In addition, if the deceased has metal fillings, artificial joints or other non-organic ingredients, they are released as toxic gases.
The other option, burial, is no greener. Most caskets are not very eco-friendly (though there's been progress), and bodies are often embalmed before burial, which means those chemicals inevitably end up in the top soil. Plus, cemeteries take up an enormous amount of space."
Ben then explains
"In Bio-Cremation, a process known as alkaline hydrolysis essentially dissolves the body in a hot bath of chemicals, liquefying the soft tissue and leaving only bone and "a syrupy brown liquid." That liquid either goes down the drain, or can be captured and handed over to relatives along with the bone. The whole process takes about two hours and uses one tenth the natural gas and one third the electricity. Furthermore, because there is no exhaust gases, crematoriums do not need zoning permission to install a smokestack (or deal with neighbors unhappy with the smoke)."
