Sewer Blockages & Flooding
Oil does not mix with water. It is denser and solidifies easily when cooled, hardening into thick layers,
blocking drain pipes and causing serious damage to sewerage systems. More than £90 million is spent
every year in the UK alone clearing fat oil and grease blockages.
These obstructions account for 80% of sewer flooding incidents in the UK and more that 5,000
properties are flooded annually as a result. There are approximately 370,000 sewer blockages
throughout the UK every year.
Strong chemicals are needed to unclog pipes. These chemicals then break up in the water and are
dispersed into our rivers, seas and oceans. Although oil does break down in water, in doing so it
consumes vast quantities of oxygen causing oxygen levels to drop drastically and in severe cases
water can no longer support fish, insects and animals that live in and around it.
According to the US Environmental Protection Agency, spills of animal fats and vegetable
oils have the same or similar devastating impacts on the aquatic environment as petroleum oils.
Increased Greenhouse Gas Emissions
When waste vegetable oils are dumped into landfill they decompose anaerobically to release methane.
According to US Environmental Protection Agency estimates, methane traps up to 100 times more heat
in the atmosphere than carbon dioxide within a 5-year period and 72 times within a 20-year period.
Global vegetable oil production amounted to around 182 million metric tons in 2016/2017 and
sunflower seed oil consumption around 16.52 million metric tons worldwide. It is estimated that
one litre of UCO can contaminate up to one thousand litres of water.
When completed our Kingsnorth Site will process 10,000 metric tonnes of waste oil per month.
Our electrical generation plant will output 60MWh per day to the National Grid.
Our total electrical output in one year will be enough to power over 5,500 homes.
