Abstract
The waste management solutions in landfills of Latvia differ. Some of them are
developed according to the concept of biogas production and use in power plants
or cogeneration plants (CHP). The use of biogas in CHP depends on energy
consumption and supply, and availability of energy consumers. More often are
cases when there are no possibilities to connect heat energy consumers, which
create problems of the low energy efficiency of power plants’ operation.
A structure of energy user in Latvia is characterized by high energy
consumption in households, public and service sector, compared with relatively
low consumption in the rural and industrial sector. This situation obligates
special tasks for power sector development, especially choosing energy resources
to ensure energy production and supply. In Latvia imported fossil and renewable
energy resources are used. A use of specific energy resource depends on an
energy supply policy, and total consumption of energy resources depends on the
development of every type of energy resources in regions. Now there is an
unjustified high proportion of fossil fuel in state energy balance which it is
possible to reduce by beginning the active use of local fuel in regions.
RDF and landfill gas as a renewable energy source could play a role in the
development of local energy resources in Latvia, which should be based on
principles of cluster, integration and gradualness. In this paper the main attention
is paid to waste management problems from the development of a regional
power supply system point of view together with understanding, that those are
not two separate systems, but two parts of one system with dynamic rather than
static development.
Keywords: biogas, landfill gas, refuse derived fuel, regional energy supply,
renewable energy sources, system analysis.
