Case analyses of low-carbon technology transfer from the co-benefit perspective

This article presents two case analyses of low-carbon technology transfer between Japan
and China. One technology is waste heat recovery power generation in cement kiln
(WHR system) and the other is co-processing of wastes using cement kiln, namely the
CKK system (Conch Kawasaki Kiln System). The WHR system has significant co-benefit in
the reduction of air pollutants and carbon emissions. The co-benefit of CKK technology
is the improvement of local social welfare. There is no financial barrier for the application
of WHR, whereas policy barriers exist for the diffusion of CKK technology. It is expected
for the CKK system to enjoy preferential electricity pricing policy and tax reductions as
are available for general waste-to-power facilities. The success in the transfer of target
technologies may be attributed to the symbiotic business model comprising the related
companies.
