Organic wastes make up approximately 40 percent of the residential solid waste generated in Canada. Most of the municipalities in Canada set a target to divert the organic waste from landfill due to various adverse environmental effects including emission of greenhouse gases. Hence, there has been a growing interest in sustainable technologies for organic waste treatment. The proposed research will investigate emerging electrochemically assisted biotechnologies, such as electro-assisted digester, and microbial electrochemical cell (MXC) to promote simultaneous treatment and resources recovery from the organic fraction of solid waste.To develop electrochemically assisted biotechnologies for resources recovery from organic waste, the applicant will focus on two research themes. The first research theme will focus on the understanding of the fundamentals limiting process kinetics of electro-assisted digestion for bio-methane production. The second research theme will concentrate on the engineering aspects including organic waste pre-treatment, and optimization of the electrode configuration for improving electro-assisted digestion. Furthermore, MXC will be investigated for chemical oxidant production from electro-assisted digester effluent which can potentially offset the organic waste pre-treatment cost.The proposed research integrates broad aspects of microbial electrochemistry, microbiology, and environmental biotechnology. The research methodology involves laboratory-scale experiments, advanced electrochemical techniques, design and optimization of advanced engineering concepts and bioreactors. This program will allow highly qualified personnel (HQP) to acquire hands-on experience and expertise with the advanced analytical techniques which are highly desirable in Canada, as the number of employment opportunities in bioenergy and resource recovery sectors is expected to grow substantially. The successful completion of the proposed research will significantly stimulate the diversion of organic waste from landfill. Ultimately, this research will ensure a sustainable and healthy environment for Canadians.

有机废物约占加拿大产生的住宅固体废物的40％。加拿大的大多数城市因各种不利的环境影响，包括温室气体的排放，将有机废物从垃圾填埋场转移了一个目标。因此，对有机废物处理的可持续技术越来越感兴趣。拟议的研究将调查新兴的电化学辅助生物技术，例如电辅助消化酯和微生物电化学细胞（MXC），以促进从固体废物的有机分数中促进和资源恢复。开发电化学辅助的生物技术以从有机物浪费中恢复了有机浪费的资源，将重点介绍了两种研究。第一个研究主题将重点介绍对生物甲烷产生电辅助消化的基础知识动力学的理解。第二个研究主题将集中于工程方面，包括有机废物预处理以及优化电极配置，以改善电辅助消化。此外，将研究MXC从电辅助消化池的化学氧化剂生产中，这可能会抵消有机废物的预处理成本。拟议的研究整合了微生物电化学，微生物学和环境生物技术的广泛方面。研究方法涉及实验室规模的实验，先进的电化学技术，高级工程概念和生物反应器的设计和优化。该计划将允许高素质的人员（HQP）通过高级分析技术获得实践经验和专业知识，而这些分析技术在加拿大非常可取，因为预计生物能源和资源回收领域的就业机会数量将大大增长。拟议的研究的成功完成将显着刺激有机废物从垃圾填埋场的转移。最终，这项研究将确保加拿大人的可持续健康环境。
