Today cremation of body is getting popular as compared to burial. During a cremation process, a dead body is reduced to bone fragments with the help of high heat and temperature. But as the standard cremation process is not good for the environment a relatively new concept has emerged. This new concept is known as bio cremation or green cremation.
With the traditional cremation process there is always the risk of increasing the level of carbon dioxide in the air which results in global warming. Also there are chances of other pollutants like dioxins and mercury level increasing in the air with the traditional cremation process. Due to all this negative aspects, the eco friendly concept of bio cremation emerged.
What is bio cremation?
This is a kind of cremation where instead to fire, water mixed with an alkali solution of potassium hydroxide (KOH) is used to reduce the body to bones. The whole process of bio cremation gives stress on the natural decomposition of the body through the use of water and an alkali solution where a balanced form of pressure, water and chemicals are used. At the end the family members of the deceased get the ashes.
It is a kind of green funeral option that makes the final resting place of a person more eco friendly. Here no pollutants like carbon dioxide and mercury come in contact with the air and the liquid used here becomes sterile that can be drained into the sewer system without worrying about any side effects.
During the bio cremation or green cremation, some eight times less energy is required as compared to a traditional cremation process. Less use of energy means less damage to the environment and a cost effective way to process the remains after death.
The process of bio cremation:
During bio cremation, the body of the deceased is placed into a pressurized stainless steel cremation chamber. Here water and alkaline solution are automaticllay pumped into the container at a ratio of 95% water and 5% alkaline. Finally the temperature of the chamber is raised to 350°F. The balanced form of pressure, water and chemicals causes a kind of reaction that begins and completes the cremation process. After two to three hours, all that is left inside the chamber are bone residues and a sterile brown liquid that can be flushed down the drain. The bones are rinsed and crushed to form ashes and then it is finally returned to the family.
The chemicals used during the process of bio cremation are used in many cosmetic and home sanitation products. These chemicals do not cause any odor during the whole process of cremation and later on the liquid can be safely drained into the sewer system. For bio cremation protein based materials can be used for making a casket or clothes made of silk or wool as such products can be easily destroyed during the cremation process leaving behind just white bone fragments.
Bio Cremation and Environment:
This eco-friendly cremation process is highly good for the environment as:
- No mercury or air emissions happen with bio cremation
- It hugely reduces the amount of ‘Carbon Footprint’ in the air
- It retains around 20-30% more bone fragments as compared to flame cremation
- The operating cost of bio cremation is much less as compared to flame cremation
- Minimizes the requirements of energy
- There is no need of cremation containers
- The medical implants done in the body of the deceased can be easily recycled
- No need of stack for air emissions discharge
- It has no harmful chemical or microbial contaminations
To conclude, bio cremation is an environmentally focused way of disposing a dead body. Also looking at how people are becoming more conscious about their environment, more and more will opt for bio cremation process in near future.
