The community waste to energy plant facility in Washington DC (Blue Plains) is the first one of its type and cost nearly 500 million dollars.
Methane is created via an anaerobic digestion procedure following the thermal hydrolysis of solids under pressure.
The captured methane is utilized in a CHP (Combined Heat and Power) system that produces about 30% of ….
the energy requirements of the whole 157 acre plant.
The Combined Heat and Power arrangement lowers the costs to operate the plant significantly. With about ten million dollars saved per year on electricity with this waste to energy process. Whilst at the same time helping the environment by emitting less carbon dioxide.
Blue Plains can ‘chew’ through 370 million galls. per day of sewage from Maryland, Virginia and the District.
Not only that but the amount of bio solids is reduced by half. This means reduced costs and additional savings from transporting less bio solids. From waste to energy can have benefits.
Because the bio solids produced from the digestion are now a higher grade (in fact Class A), they qualify to be accepted as a fertilizer for gardening and landscaping.
At the opening of the Blue Plains facility this fertilizer was used in a tree plating ceremony. This was witnessed by both federal and local officials. These included the D.C Mayor, D.C Water CEO and acting deputy administrator for the EPA ( Environmental Protection Agency).
The use of Combined Heat and Power in this type of treatment plant can be seen to be ideal for the recovery of energy.
Combined Heat and Power technology can be set up quickly, is cost effective and the location not restrictive. This is excellent as there over a thousand suitable sites country wide that save money and help the environment by utilizing this technology.
Combined Heat and Power systems are also ideal for the security sector. This is due to their ability to overcome any power outages and disruptions. They can ‘power on’ regardless!
This is accomplished via a range of regional Combined Heat and Power technical help associations and via various Energy Dept. programs; SEP ( Superior Energy Performance) and Better Plants.
To summarize, the Blue Plains’ Combined heat and power system supplies a budget friendly solution to enhance the future of the area’s energy, environment and financial outlook.
* Waste to energy reference: The anaerobic digestion process is a combination of several. With no oxygen present biodegradable substances are broken down by micro-organisms. The process is used to produce fuel and/or manage waste in both domestic and commercial sectors. Anaerobic digestion is also used in the food and drink sector as well as domestic fermentation.
Anaerobic digestion is also called anaerobic activity when it takes place in soil and sediments in lakes and oceans. Marsh gas (Methane) is a product of such a process. This gas was discovered in 1776 by Volta.
