Tag: anaerobic digester

Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste and/or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion.

Methods to Handle Organic Waste: Compost and Kilowatts

In 1915, a tragic farm accident reported in The Fruit Grower and Farmer was a mere footnote of local news. Patients from the State Hospital in Athens, OH, whose job was “to tramp down the silage comprised of corn stalks and leaves” were found asphyxiated in a tower silo. The report says

The Costs and Benefits of Anaerobic Digesters

The Costs and Benefits of Anaerobic Digesters

Anaerobic digesters are a mature, proven technology. They take sludge, manure, and other organic waste materials and produce methane (natural gas) fuel. Nobody questions their technological capabilities. However, the question remains as to their economic benefits. In terms of dollars and cents, how much economic sense do anaerobic digesters make?

Making Power Multitask With CHP/CCHP

Making Power Multitask With CHP/CCHP

Cogeneration, or combined heat and power (CHP), uses a heat engine or power station to generate electricity and heat for onsite uses. Trigeneration, or combined cooling, heat, and power (CCHP), is the simultaneous generation of electricity and useful heating and cooling as a result of the combustion of fuel or

Better Together

“Waste not want not” is a respected proverb in many engineering applications. However, according to the three laws of thermodynamics, waste heat is inevitable in any working system. And, while it is physically impossible to prevent the generation of waste heat, a power system operator can make a virtue out

A New Solar Array Comes to Life at Vermont Tech

RANDOLPH, VT – MAY 18, 2016 Vermont Technical College has flipped the switch on a new solar farm that is projected to produce nearly 1 million kWh of clean, Vermont renewable energy each year. The array of 100 locally manufactured solar trackers by AllEarth Renewables, Inc. of Williston, Vt., has
