What Does Anaerobic Digestion MeanAnaerobic Digestion is a process that creates energy and biofertiliser from food waste, but what does anaerobic really mean?

As one of Pennsylvania’s leaders in Anaerobic Digestion we are continuously doing our best to educate people about the benefits of recycling and how Anaerobic Digestion can help us create energy for thousands through-out Pennsylvania.

Anaerobic Digestion is a process of breaking down food waste and other organic matter into biogas and biofertiliser. The Anaerobic part is the one that is most misunderstood.

The “Anaerobic” in  Anaerobic Digestion simply means ‘in the absence of oxygen’.  The organic matter that is broken down to create renewable energy from Anaerobic Digestion is done so in sealed tanks that are in the absence of oxygen’.

Anaerobic Digestion is nothing new. Evidence indicates biogas was being used to heat bathing water during the 10 century BC in Assyria and in Persia during the 16th century.

The first digestion plant was built at a leper colony in Bombay, India in 1859.  Anaerobic Digestion reached England in 1895 when biogas was recovered from a “carefully designed” sewage treatment facility and used to fuel street lamps in Exeter.

Worldwide, more than 1,000 vendor-supplied systems now operate or are under construction. It is estimated that European plants comprise 44% of the installed base. Only 14% of the Anaerobic Digestion systems are located in North America.

Although the first Anaerobic Digestion to use MSW as a feedstock operated in the United States from 1939-1974, it is receiving renewed interest.

In the world of Anaerobic Digestion technology, farm-based facilities are perhaps the most common here in Pennsylvania as well as through the world.

Every ton of food waste recycled by Anaerobic Digestion as an alternative to landfill prevents between 0.5 and 1.0 ton of CO2 entering the atmosphere.
