Fuel Grade Tallow

All grades of tallow (animal fat) can be used as liquid fuels in place of fossil fuel oils or vegetable oils. However, tallow from Category 1 animal by-products is principally used for this purpose since tallow from other categories (and especially Category 3) has other commercial uses i.e. processed animal proteins.

The calorific value of tallow is just over 90% that of fuel oil and minimal modification of combustion equipment is needed to burn it. Direct emissions from tallow combustion in the form of particulates and sulphur dioxide (an 'acid gas') are considerably lower for tallow combustion than for fossil fuel oil combustion.

Because tallow is a renewable resource burning it in place of fossil fuels reduces overall greenhouse gas emissions.

As well as being burned directly as a renewable fuel, tallow can be used to manufacture diesel fuel (biodiesel). This production and use is a key element in allowing the UK and Europe to achieve a target of 5.75% of all road transport fuels to be biofuels by 2010.
