Biogas - Digestate As Fertilizer

Treatment of animal manure and slurries in biogas plants results in biodegradation of organic matter to inorganic compounds and methane.
In practice, the anaerobic degradation rate of organic matter from animal manure and slurries is about 40% for cattle slurry and of 65% for pig slurry.

The degradation rate depends at large on feedstock type as showed in table 1.
Due to degradation of organic matter, digestate is easier to pump and easier to apply as fertilizer, with reduced need of stirring, compared to untreated slurry.

Efficiency From Hydrophobic Surfaces

Video presentation by Karen Gleason professor in the Department of Chemical Engineering at MIT.

Presentation is about increasing efficiency by using hydrophobic surfaces in heat transfer, in this example it is increasing efficiency in condenser in steam power plants.
Using the hydrophobic surface can increase total efficiency in steam power plant by total of 4%.

Utilization And Properties Of Biogas

Biogas has many energy utilisations, depending on the nature of the biogas source and the local demand. Generally, biogas can be used for heat production by direct combustion, electricity production by fuel cells or micro-turbines, CHP generation or as vehicle fuel.

Helping You Identify Energy Savings In Lighting

Best way to save energy is to switch to energy saving light bulbs. Best energy saving light bulbs are LED light bulbs.

LED light bulbs can save you up to 75% energy. In chart bellow you can see energy savings and consumption with LED light bulbs versus traditional light bulbs.
