Before the final curtain is drawn on our lives, we can make environmentally friendly choices as to how our funeral and burial is conducted.

When my mother passed away at the age of 50, it was an incredibly sad time. While I had experienced death through my work at  a hospital, I had never been to a funeral - that process was a mystery to me. Her decisions as to what should be done with her remains reflected upon the way she led her life - humbly and always thinking of others.

She requested that there be no embalming, no viewing, no monuments, a simple  and small service, no flowers, a very simple casket and cremation. Her ashes were spread in places she loved in Australia and around the world. People overseas held their own small services to commemorate her.

While my mother loved nature, I don't know if her decisions were environmentally motivated and I doubt so, but more that she didn't want to be a bother; bless her :). We were lucky enough to have an excellent funeral director and I learned a great deal during the process about how we treat our dead.

Death in developed countries is generally not very environmentally friendly. It's often a reflection of our lives as consumers. While a funeral is an important part of the grieving process for those of us left behind, there's much we can do to have less of an impact on the environment when we pass on.

Embalming

After we die, if our wishes are for an open casket viewing, we need to be embalmed. The following are the more invasive aspects of that process (a warning to the queasy):

1. Arterial embalming - injection of embalming chemicals into the blood vessels
2. Cavity embalming - internal fluids removed and more embalming chemicals placed into cavities.
3. Hypodermic embalming, more embalming chemicals under the skin where required.
4. Surface embalming in cases of viewable injuries.

Cosmetics may also be applied, also fragrances.

Embalming fluid is usually made up of formaldehyde, methanol and ethanol. Formaldehyde is carcinogenic and a common environmental pollutant.

Do you really wish for this to happen to your body? Is a viewing necessary? I'm not criticizing if you do; but these are aspects you may not have considered.

Caskets and coffins

Then comes the casket or coffin - aside from being horribly expensive and the energy used to create elaborate coffins, they are often made with various plastics, varnishes solvents and glues, with some even being lead lined. Coffins made from particle board also contain formaldehyde. These chemicals leach into the surrounding soil and in the case of cremation, can release dioxins, hydrochloric acid, sulphur dioxide, carbon dioxide and other chemicals.

The funeral service

The funeral itself can be an elaborate and resource intensive affair with flowers, motorcades and  people travelling from all points of the globe to attend. Burial is also taking up increasing amounts of land - acres and acres of marble slabs, headstones and not much else.

About cremation

Cremation has gained popularity in developing countries over the past couple of decades. It could be considered greener in many ways, but isn't without its issues; particularly if a coffin is cremated along with the deceased. A great deal of energy is needed to cremate a body. Most crematoriums no longer use coal but natural gas or propane. However, the temperatures required are around 870–980C (1,598–1,796F) and the average time is around 90 minutes. Emissions from crematories include nitrogen oxides, carbon monoxide, sulfur dioxide, mercury, hydrofluoric acid and hydrochloric acid.

Greening death

For the environmentally conscious person concerned as much about the impact of their death on nature as they are of their life; many funeral directors are recognizing this and offering green funerals and burials.

For instance, in relation to caskets there are more readily biodegrable options such as this wicker casket:

.. and this is a concept I really like - the coffin cover:

The body is placed into a cardboard box which is then slid into the coffin cover for the service. After the service, the cardboard box is removed and buried or cremated. The cover can then be reused. This option means less trees are used for making coffins, it speeds up the decomposition process and also decreases the amount of energy needed if the remains are to be cremated.

The coffin cover not only makes good environmental sense, but also financial - cardboard coffins cost a fraction of even the simplest solid wood caskets. Other environmentally friendly caskets are made from cornstarch, bamboo or recycled paper. In the Middle East, a simple shroud is often used.

Some funerals don't take place until many days after the person has passed on. In some cultures, they must bury their dead within 24 hours - this means that bodies don't need to be refrigerated for days on end and makes good hygienic and environmental sense. If you make your funeral arrangements well in advance, it may be possible to shorten the length of time between your passing and interment or cremation.

For the service, you can state that you don't wish for flowers, but request that money that would have been spent on flowers be donated to charity. Perhaps you could also suggest the money be used for offsetting travel to the service through the purchase of green tags or carbon offsets.

As for a resting place, natural burial grounds are now springing up in many countries. These are usually woodlands, forests or reserves. Large monuments aren't permitted to be erected, just simple plaques - you basically blend in with the environment.

Cremation alternative - Resomation

As mentioned, cremation isn't without its problems environmentally speaking - but there's now an alternative called "Resomation". Around the same cost of cremation, resomation is a water/alkali based alternative with significant environmental benefits according to the creators of the process. It reportedly uses less energy than cremation, generates less carbon dioxide and avoids mercury and other harmful contaminants being pumped into the atmosphere. 

It is supposedly an accelerated form of natural decomposition chemistry. The ash produced instead being like the color of fireplace ash, is pure white (not that it really matters). While a traditional wood coffin can't be Resomated, a coffin can act as a temporary casket and the deceased is contained in an "silk coffin" inside, which are then resomated. It's an interesting process that is still undergoing approvals in various countries - you can learn more about resomation here.

Personally, I'm hoping that (after organ donation) what remains of me can be buried in a shroud or perhaps resomated and interred on my chunk o' dirt in the outback. I would like my ashes scattered or a native tree planted over me and I would also want the property to be turned into a heritage/nature reserve so that other kindred spirits may always be able to enjoy the peace I was privileged to experience there (well, mostly - aside from the noise pollution from inconsiderate neighbors' dirt-bikes from time to time!). That's it.

If there is indeed an afterlife, knowing that those wishes have been observed would certainly help me rest in peace. I'm also mentioning this as my will still isn't done - so at least my wishes for how my remains are to be dealt with is now a matter of public record :).

As in life, we can approach the sensitive issue of our death with green issues close to mind. - but be sure to discuss your wishes with your family and make prior arrangements wherever possible to help minimize the stress on your loved ones after you have passed on... it's something I certainly need to formalize!
