1. The role of bioenergy to meet the renewable energy target for New Zealand
Dr. Per S. Nielsen

2. Introduction The NZ energy sector is in-efficient
Electricity is to a large extend used to cover space heating and hot water demand

3. Introduction Waste Minimisation Strategy
National Energy Efficiency and Conservation Strategy
The Climate Change Policy
Renewable Energy Target

4. NZ Waste minimisation Strategy
By 2003 all territorial local authorities have instituted measurement programmes to identify existing organic waste quantities, and set local targets for diversion from disposal
By 2010 the diversion of commercial organic wastes from landfills to beneficial use will have exceeded 95%
By 2005 full cost charging policies are established and cleanfills comply with guidelines

5. Climate Change Policy
Reduce average GHG emissions to 1990 levels between
In 2001 the energy sector contributed 39% of NZ’s GHG emissions (31 Mtons CO2 eq)
The waste sector contributed 5% or 2.3 Mtons CO2 eq.

6. Renewable Energy Target
Renewable energy target 30 PJ/year in additional energy (basis 2000).
This is an increase from PJ/year in 2000 to PJ/year in 2012.

24. Conclusions 13.7 Mtons of organic
Another PJ per year potentially available.
Replacing use of electricity has the highest CO2 benefit
Utilising the more “difficult” organic waste streams also help avoid emission of CH4 from landfills.
