Title: Sustainable Redevelopment of an Uncontrolled Dumping Site into an Integrated Waste Recycling and Treatment Centre, Moen, Belgium


1
Sustainable Redevelopment of an Uncontrolled
Dumping Site into an Integrated Waste Recycling
and Treatment Centre, Moen, Belgium
Dr. S. Helsen Zagreb 25/11/2010

Intermunicipal Organisation IMOG
Intermunicipal waste organisation in Flanders
(BE) 11 municipalities pop. 227.000 Yearly
turnover 26 million euro (2009) 200 employees

IMOG Objectives
  • Treatment of household waste through sustainable
    waste management

3
4
Overview landfill expansions and current
activities
  • Initiatives reduce and recycle waste
  • Business plan
  • for expansion
  • of landfill
  • Old landfill covered and remediated

4
5
Clay quarry landfill expansion
  • Excavation of quarry for brick industry
  • Excavated clay reused as seal
  • Covered landfill partly developed as treatment
    centre for dredged sediments

5
6
Secondary use covered landfill
Delivery of cat. 1 waste (industrial waste)
reduced Emphasis on cat. 2 waste (mainly
household waste) Groundwater pollution
(metals, salts,) landfill leachate constitutes
risk to environment and nearby waterway To
prevent further spreading ? soil remediation
project Hydrogeologically isolating entire
landfill site
Groundwater protection
6
7
Groundwater protection
  • Impermeable cement-bentonite slurry wall around
    landfill site
  • Wall to depth of 20 m below groundsurface
  • Quality control procedure to ensure depth was
    reached
  • Groundwater flow and water levels calculated by
    modeling and compared to field data

7
8
Wastewater treatment
  • Wastewaters evacuated to biological treatment
    plant
  • Rain
  • Water seeping through the landfill
  • Runoffs
  • Wheel washing residues
  • Domestic waste water
  • Optimal treatment efficiency through operated
  • and monitored facility
  • BATNEEC principles

Management of waste fractions
Processing through incineration (Harelbeke site) ? 1.6 billion kg
Production of electricity ? 600 m. kwh
Removal through landfill ? 1.5 billion kg
Selective collection of paper and cardboard ? 220 m.kg
Selective collection of glass bottles and jars ? 100 m. kg
Composting of green waste ? 300 m.kg
Producing and marketing of compost ? 75 million kg
11
12
Collected quantities waste fractions civic
amenity sites
  • Operation of 16 civic amenity sites
  • Separate collection of 40 waste fractions
  • Differential pricing applied
  • pay according to type
  • and quantity of materials
  • following polluter pays,
  • the preventer saves

12
13
Sorting centers for bulky waste
  • Sorting centers for
  • bulky waste sorting line
  • wood waste sorting
  • cleaning line
  • Manual and mechanical
  • sorting for
  • paper and cardboard
  • inert building materials
  • wood, plastics, ....
  • Non-recyclable fraction
  • sent to compactor

13
14
Wood sorting centre
  • Wood waste segregated into
  • untreated
  • treated,
  • uncontaminated
  • contaminated
  • Crushed and sieved into fractions
  • Used as biomass for energy and/or MDF wood

14
15
Composting
  • Green waste sorting and processing important
  • Respond to demand
  • new equipment trucks, sieving and shredding
  • machinery
  • new composting and maturation areas constructed
  • building of area for sieved compost
  • quality label developed and compost market
    explored
  • 30.000 ton green waste to composting installation
  • 13.000 ton compost and 3000 ton wood chips sold
    on
  • local market

15
16
Treatment street sweep refuse
  • Street sweep refuse picked up by brush or sweep
    trucks
  • Litter, sand, leaves and small branches
  • Optimization of waste sorting line
  • Waste cleaned and segregated
  • sand fraction ? reused as a secondary raw
    material
  • plastic
  • metal
  • green waste
  • combustible waste

16
17
Treatment dredged sediments
  • High demand treatment dredged sediments from
  • navigable and non-navigable waterways
  • Development of treatment centre for dredged
    sediments
  • Dredged sediments
  • Arrive by ship over the adjacent waterway
  • Dewatering
  • Material excavated and removed once dry
  • Use for final landfill cover or as filling
    materials
  • in road constructions or noise barriers

18
Biomass centre
  • 1999 ? selective collection, sorting and
    treatment
  • of wood waste
  • Wood collected at civic amenity sites recycled
  • (production of MDF board)
  • 2005 ? non-recyclable wood biomass power plant
  • (green energy)
  • Every year 30.000 ton of biomass produced
  • 41 million kWh electric consumption for pop.
    32.000

19
Potential landfill gas extraction
  • 12 vertical wells
  • Horiz. HDPE pipes
  • to central location
  • gt 500 m³/hr
  • combustion engine electricity
  • lt 500 m³/hr
  • Micro turbine
  • electricity
  • Flare system

19
20
Solar energy park
  • Landfill closed after care and monitoring for 30
    yrs
  • Site developed cfr. local / regional planning
    regulations
  • 2 ha of solar panels on old landfill
  • Electrical energy used on site excess through
    the grid
  • Entire landfill closed
  • 10 ha of photovoltaic cells
  • Energy for 1500 families

20
21
Exporting forty years of knowhow
  • Success based on
  • Use of various communication methods
  • Public awareness
  • Education encouraging waste prevention and
  • Improving sorting at source
  • Secondary materials quality
  • Creates social basis for waste management
    practices
  • Aim export technical and operational knowledge
  • Collaborations with EU partners in transitional
    and developing countries, incl. Western Balkans

21
22
Conclusion
  • Waste
  • Source for secondary materials and renewable
    energy
  • Creates job opportunities and profits
  • Management demands investment with risks
  • Management requires technical skills, technology,
    organization and monitoring
