Combustible
Renewables and Waste
This heading covers combustible renewables
& waste comprises solid biomass and animal products, gas/liquids
from biomass, industrial waste and municipal waste. Biomass is defined
as any plant matter used directly as fuel or converted into fuels
or electricity and/or heat. Included here are wood, vegetal waste
(including wood waste and crops used for energy production), ethanol,
animal materials/wastes and sulphite lyes. (Sulphite lyes are also
known as "black liquor" and are an alkaline spent liquor from the
digesters in the production of sulphate or soda pulp during the
manufacture of paper. The energy content derives from the lignin
removed from the wood pulp.) Municipal waste comprises wastes produced
by the residential, commercial and public service sectors that are
collected by local authorities for disposal in a central location
for the production of heat and/or power. Hospital waste is included
in this category. Data under this heading are often based on small
sample surveys or other incomplete information. Thus the data give
only a broad impression of developments, and are not strictly comparable
between countries. In some cases complete categories of vegetal
fuel are omitted through lack of information. For more information
on a fuel type, please see the following list:
-
Liquids from Biomass
Biomass gases are derived principally from the anaerobic
fermentation of biomass and solid wastes and combusted to produce
heat and/or power. Included in this category are landfill gas and
sludge gas (sewage gas and gas from animal slurries). Bio-additives
such as ethanol are also included in this category.
Industrial Waste
Industrial waste consists of solid and liquid products combusted
directly (usually in specialised plants, e.g. tyres) to produce
heat and/or power.
Municipal Waste
Municipal waste consists of products that are combusted directly
to produce heat and/or power and comprises wastes produced by the
residential, commercial and public services sectors that are collected
by local authorities for disposal in a central location. Hospital
waste is included in this category.
Solid Biomass and Animal
Products
Biomass is defined as any plant matter used directly as fuel or
converted into other forms before combustion. Included are wood,
vegetal waste (including wood waste and crops used for energy production),
animal materials/wastes and sulphite lyes, also known as "black
liquor" (an alkaline spent liquor from the digesters in the production
of sulphate or soda pulp during the manufacture of paper where
the
energy content derives from the lignin removed from the wood pulp).
