项目摘要

With annual CO2 emission over half a billion ton, Canada is the ninth largest CO2 producer country in the world. As one of the country that accepted the Paris agreement, Canada should impose and implement green energy policy from year 2020 to decrease the carbon emission. More than 5% of this CO2 release is related to mining industries, which use in different aspects such as, transportation and processing and smelter. Replacement of fossil fuels with biomass pellet is one of the way that EMISPEC is targeting. Algae is an autotrophic microorganism capable of capturing huge amounts of carbon dioxide as a source of carbon, when ammonia and phosphorus sources are available. Mining industry produce huge amount of effluent with high nitrogen concentration, as well as carbon dioxide emissions from ore processing; factors highly required for algae growth. CTRI will collaborate with EMISPEC to demonstrate the feasibility of algae utilization in mine effluent treatment system and biomass production. Upon collaboration in this project, not only a new CO2 capturing technique by algae will be investigated, but also EMISPEC could secure the biomass required for heat generation from process dewatering. This project will benefit from a multidisciplinary team and an operational R&D infrastructure; essential ingredients for achieving the project's objectives within the given deadlines.

加拿大每年的二氧化碳排放量超过5亿吨，是世界上第九大二氧化碳生产国。作为巴黎协定的签署国之一，加拿大应该从2020年开始实施绿色能源政策，以减少碳排放。超过5%的二氧化碳排放与采矿业有关，这些行业用于运输，加工和冶炼等不同方面。用生物质颗粒替代化石燃料是EMISPEC的目标之一。藻类是一种能够捕获大量二氧化碳作为碳源的自养微生物，当氨和磷源可用时。采矿业产生大量高氮浓度的废水，以及矿石加工产生的二氧化碳排放;藻类生长高度需要的因素。CTRI将与EMISPEC合作，展示藻类在矿山废水处理系统和生物质生产中的可行性。在该项目的合作中，不仅将研究一种新的藻类CO2捕集技术，而且EMISPEC还可以确保脱水过程中产生热量所需的生物质。该项目将受益于一个多学科的团队和一个可操作的研发基础设施;在给定的期限内实现项目目标的基本要素。
