  1. New developments and insights on the effects of kitchen & garden waste processing and the structural positive contribution to reduce global warming The relationship between compost plants and Kyoto John van Haeff, Manager Converteren, Essent Milieu

  2. Central question • Kyoto challenge in the Netherlands: 13 million tons CO2 emission equivalents must be saved in 2010 (a 6% reduction compared to1990) • To what extent is the compost sector able to contribute this challenge as part of the waste industry? • How many CO2 emission equivalents can municipalities and authorities achieve and save extra?

  3. Two parts • Current status second generation compost plants • II. The meaning of compost for the Netherlands

  4. Current status second generation compost plants

  5. 2003: refurbished compost plant in Maastricht

  7. Photographs compost plant in Maastricht

  8. Production results • Primary products: • Soil improvers product certificate German BGK • Peat substitutes conform RHP guidelines • Secondary products: • Biomass green energy Tunka®, conform Dutch BRL biomass • Maastricht processes annually 100,000 tons kitchen & garden waste • Only 1% not used usefully

  9. Conclusion part 1 • Solid infrastructure in processing of selective collected municipality organic waste • Proven technology • Low cost operation • Compostindustry facilates process of reducing organic waste on landfill • EU biowaste legislation is necessary to facilate further growth in old EU memberstates and to devellop compostplants in new EU memberstates

  10. II. The significance of compost in the Netherlands

  11. Compost: contributes to soil fertility • Thanks to compost: more efficient use of minerals, in conformity with Nitrate guideline. Recognition in the Netherlands through partial dispensation • If organic content agricultural ground < 1%, then: • no ground water protection • no food production • no energy crops cultivation (and therefore no biomass) • In Europe 20% of agricultural acreage dropped to organic content < 1%!

  12. Organic content chart Europe

  13. Compost: contribution to decrease CO2 emissions • Binding organic matter: the carbon storage place • Reduction in peat winning: compost as substitute • Reduction in CO2 burdening artificial fertilizer production, through nutrient value compost • Total reduction Dutch kitchen & garden waste sector is > around 65,000 tons CO2 emission reduction. This also applies to green waste. Together around 125,000 tons

  14. CO2-effects compost route (I)

  15. CO2-effects compost route (II)

  16. Conclusion part 2 • The Dutch kitchen & garden waste composting sector achieves 65 kilo tons extra reduction of CO2-emission each year (compared to the ‘next best alternative’) • Together with the green composting sector this represents 100-125 kilo tons CO2 per year, corresponding to around 1% of the aimed total Dutch reduction • Extra CO2-emission reduction via composting instead of incineration route • Optimal management of composting installations increases CO2-yield • Potential CO2-emission reduction needs Biowaste Directative.

  17. Conclusion • Central questions: • -To what extent is the compost sector able to contribute this challenge as part of the waste industry? • - How many CO2 emission equivalents can municipalities and authorities achieve and save extra? • Second generation Dutch compost plants belong to the best in Europe • Compost products are valuable in the context of sustainable soil management and applicable within the Nitrate Guideline • Compost production (> 1,000,000 tons) from the waste sector accounts for 1% of the total CO2 emission reduction • Targets landfill directative are supported by compost plants. • To facilate targets of landfill directative and CO2 reduction the biowaste directative is necessary
