The main waste energy feedstocks are wood waste, agricultural waste, municipal solid waste, manufacturing waste, landfill gas and sewage sludge.
Gasification is a process that converts biomass into gases. This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in the reaction.
Biomass heating systems generate heat from biomass.
Thermal conversion processes use heat as the dominant mechanism to upgrade biomass into a better and more practical fuel.
Biomass to liquid is a multi-step process of producing synthetic hydrocarbon fuels made from biomass via a thermochemical route.
A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals).
The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems.
Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.
The inboard end of a ship anchoring cable which is secured in the chain locker by the clench pin.
Vertical tubular steel posts; two of them are fastened to the rectangular base of a bollard.
Elastic cement used in place of paint to protect steel.
A mixture of extremely heavy hydrocarbons obtained from residue refining process; used for road surfacing, roofing, etc.
Coaltar, creosote (coaltar and wood), coaltar pitch, antracene oil, coaltar naphtha. See also High heat tanker BITFLOWER, and Transport of bitumen products.
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt.
A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
Cargo banned by general cargo workers for some reason. For example because the cargo is dangerous or hazardous to health.
A slang expression referring to the personnel in the engine department aboard ship, that has an origin back to coal powered ships.
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
Crude oil, furnace oil, fuel oil, also tar and asphalt.
A method of starting or restarting power generation and supply to a power grid without use or reliance on external power supply.
