In the effort to be green,
UK Government has unwittingly unleashed
a new, invisible pollution problem
on forecourt owners

The Biofuel Paradox

The problem of environmental
Ethanol and BTEX pollution from forecourts
will get worse over time as the %
of bio matter in fuel increases.

The Biofuel Paradox

Filtering oil and water is pretty
straightforward. But what
if the really dangerous pollutants hide
themselves in the water?

The Biofuel Paradox

A scientific breakthrough means £200
is the difference between
forecourt biofuel protection
and biofuel pollution.

The Biofuel Paradox

BTEX are particularly destructive contaminants.
When they hide in water they become
a formidable environmental enemy.

Environmental Impact of The Biofuel Paradox

What is the Environmental Impact of BTEX?

BTEX refers to the chemicals Benzene, Toluene, Ethylbenzene and Xylene. The term BTEX reflects the fact that the substances are often found together at contaminated sites. All four of these hazardous components are found in petroleum products.

BTEX compounds are involved in the formation of ground level ozone that can be damaging to plants and materials. The properties of BTEX compounds mean that most releases end up in the atmosphere, although some can be bound (relatively briefly) to soils and sediments. They react with other air pollution and are broken down, returned to the earth or involved in the formation of photochemical smog. Higher concentrations of BTEX resulting from a spillage are moderately toxic to aquatic life.

How does BTEX affect human health?

Long-term exposure to high concentrations of BTEX (usually only experienced in occupational settings) is toxic – damaging the liver, kidneys, central nervous system and eyes. Inhalation of ground level ozone (in the formation of which BTEX can be involved) can exacerbate respiratory conditions such as asthma.

"The EU Renewable Energy Directive (RED) mandates that 10% of the energy from transport fuels should come from renewable sources by 2020. Therefore the UK will need at least 10% Ethanol in petrol in the future."

What are the contaminants in BTEX?

Benzene is used in the production of consumer products such as paints, nylon and plastics. Studies show that it may cause cancer and genetic damage. It is the most volatile and water-soluble of the BTEX compounds.

Toluene is a water-insoluble liquid with the smell associated with paint thinners. It is used to produce Benzene and as a solvent in paints, synthetic fragrances, adhesives, inks, and cleaning products.

Ethylbenzene is a highly flammable, colourless liquid that is important in the petrochemical industry. Ethylbenzene is also used to make other chemicals, in fuel, and as a solvent in inks, rubber adhesives, varnishes, and paints.

Xylene was named in 1851, having been discovered as a constituent of wood tar. Xylene is used as a solvent in printing, rubber, and leather industries, with several million tons being produced annually.
