Greenhouse Gases Emissions by Energy Production and Waste Disposal

Abstract

Biomass is very important source for energy production in Latvia [1]. Wood biomass – firewood, wood chips and pellets are the main part of biomass, because 54,7 % of the state area is covered by forests. Also other kinds of biomass are playing significant role in the heat and electricity production. Such kinds of biomass are various agricultural and food production residues, livestock breeding buy-products, sewage sludge, organic part of household and industrial wastes, etc. Approximately 1/3 of energy is used for household in Latvia. The significant part of energy is produced in local heating facilities. They by large part of greenhouse gases (GHG) are produced in household. In the same time gases from the municipal waste disposals are also significant source of GHG. The results of measurements and evaluation of GHG emissions from biomass burning in household boilers and municipal solid waste disposals are reported in the present work. The calculations of GHG emissions are conducted by using software and data from Latvian Environment, Geology and Meteorology Centre (LEGMC).
