Intermunicipal cooperations

Imog region: about 233.000 inhabitants• Municipalities authorised for collection and treatment of household waste• Separate companies, owned and controlled by the municipalities

Close to the inhabitants• Extensive door to door collection (signage)• Civic amenity sites as ‘point of sales’ (< 3 km)• Face-to-face communication

Seperate collection

• Network of 16 civic amenity sites

• 295 glass bottle banks

• Textile banks

• Collection at home• Household waste: weekly• Plastic and metal packaging: once every two weeks• Paper & cardboard: once every two weeks• Garden waste: weekly through garden waste bins• Bulky waste: on demand• Asbestos cement on demand• Garden waste on demand• Reusables thrift store ‘Kringloopwinkel’

Electricity production

1. Harelbeke : household incineration• 2 kg of household waste = 1 kWh• Approximately 32.000 MW (eq. 25.000 inhabitants )

2. Moen : landfill gas incineration• A high-energy mixture of methane gas, vapour gas and

oxygen : 4.750 MWh/year

3. Biomass• Incineration of non-recyclable wood

4. Photovoltaic panels• On landfill site (when finished)• On rooftop Harelbeke

Waste as a source of energy

Waste as a source of energy

Residual heat : heat network

Transport of hot water through an underground piping system.Connecting sites with a surplus of residual heat with areas withdemand

1. Internal use• Central heating and hot water• Drying biomass

2. External use• Neighbours in Harelbeke : heating for industrial proces• Heat network to public and private projects in proximate

municipalities
