Content of a presentation

• Background
• Significance of landfill gas
• Waste volumes to landfills
• Objectives of the project
• Methods
• Present state of the project
• Closing

Background

• Significance of landfill gas
• Methane is an potent greenhouse gas
• Potential energy recovery of methane
• Fire danger in landfills
• Health hazards associated with the trace gases
• Odor nuisance

5
Background

• The annual production of household and industrial
  wastes in
• Russia is about 37,5 million tons
• St. Petersburg is about 1 million ton (5 million
  m3)
• The household waste management is based mainly on
  landfilling
• 1 ton of waste produce 200 - 300 m3 landfill gas
• About 50 60 of landfill gas is methane

6
Objectives

• Review of
• the present status of the St. Petersburg waste
  management system
• generated household waste amounts
• waste management legislation in Russia
• Evaluate the current condition of the main
  landfill areas
• of the City of St. Petersburg
• Landfill gas measurements and gas analysis in
  order to
• evaluate the methane production capacity of a
  landfill
• Description of the model "How to utilise landfill
  gases in energy production and How utilize
  CO2trade mechanisms in financing

7
Methods

• The research is based on a literature search and
  on site measurements in a landfill
• Landfill gas measurements are done by a company
  Finnish Bioenergy Ltd
• Measurements are done at a landfill in Dunay
  during this summer
• 1-2 lateral gas collecting pipes will be
  installed per hectare in order to get gas samples
• Total amount of measurement points will be about
  10 - 12

8
Present state of the project

• Some results of the literature search can be seen
  at this point of study, for example
• present status of the waste management system and
  generated waste amounts
• Results of the landfill gas on site measurements
  and gas analysis are not ready yet
• Very rough estimates for the methane production
  can be given on the grounds of disposed waste
  amounts
• 40 million m3 of waste placed at Novoselky
  landfill
• 1 ton waste produces annually 5 10 m3 landfill
  gas
• gt total annually produced landfill gas 200 400
  Mm3

9
Closing words

• The meaning of the study is to provide updated
  facts to the Finnish companies that will have
  potential business opportunities on the field of
  landfill gas utilisation
• landfill gas collecting pipelines
• pumping stations
• gas engines, heat recovery boilers
• generators, systems engineering
• Continuation study will be planned
