Doing my bit for the environment

As an environmentalist I believe in recycling and minimizing the impact of our lives on the world we live in.  Use of biodiesel rather than fossil fuels helps to reduce atmospheric carbon dioxide and sulphur dioxide emissions.  The waste oils from which biodiesel is made may otherwise be dumped on landfill sites or possibly poured into the sewerage system.

The glycerol which is a by-product of the production process of biodiesel is used to help light log fires, any solid wastes go on the compost heap to benefit the garden, so every bit of the waste oil is used.  Any surplus containers are either reused or sorted into appropriate recycling skips.

The production of vegetable oil

Vegetable oil is described as a renewable fuel as it does not add any extra carbon dioxide gas to the atmosphere, as opposed to fossil fuels which are causing changes in the atmosphere. Carbon dioxide accumulation is thought to produce the greenhouse effect' high winds, rising sea levels, droughts are a few of the probable results of continued burning of fossil fuels.

Vegetable oil and biodiesel production can involve heavy processing and energy use, from sowing the seed to transporting the finished product, and of course each stage can reduce the environmental benefits - sometimes by more than 50% if it involves intensive farming techniques. 

However, if cooking oils are recycled, converted into biodiesel in a small local plant, the use of the oil is doubled - or it could be said the impact on the environment is halved.

The advantage of Biodiesel

According to the Central Science Laboratory 2005, rape methyl ester (biodiesel from rapeseed) has the potential to reduce energy inputs by 66% and total greenhouse gas emissions by 53% for each MJ of energy created.
