On 25th Oct., Climathon 2019 Shanghai was successfully held at China-UK Low Carbon College, Shanghai Jiao Tong University at Lingang campus. Climathon is a global movement aimed at solving the challenges like high energy consumption, high emission and high pollution that cities are facing today. This is manifested in a 24-hour hackathon taking place simultaneously in major cities around the world. In 2018, there were 113 cities, 46 countries and more than 5000 participants involved in this large event. Climathon Shanghai 2019 aims at collecting innovative and effective solutions in “Waste Management, recycling and utilization” and facilitating to build Shanghai Lingang into a low-carbon city and improve sustainability.

低碳学院副教授张景新首先为活动作主旨演讲“超大城市固体废弃物处理与资源化方面存在的问题和挑战以及解决方案”为参与者们提供了启迪和思路。张景新以上海交通大学与新加坡国立大学的国际合作项目E2S2为背景，介绍了废物能源化的相关技术及资源回收利用途径。并以E2S2项目开发的湿垃圾废物能源化系统为例，介绍了技术转移与商业化的发展轨迹

Prof. Zhang from LCC delivered a speech about “Municipal Solid Waste Management in Megacities for Sustainability and resource recovery” which introduced the coupled challenges and solutions for municipal solid waste management in stressed megacities. The solution proposed is an integrated waste-to-energy eco-system that is developed from a joint collaborative program between Shanghai Jiao Tong University and National University of Singapore. In the following the presentation introduces the development of a spin-off company (E2S2 Systems Pte Ltd) for the commercialization of this system. 

Lin Zhang from the Natural Step （China）delivered an excellent training on Business Model Canvas to help participants to describe, design, challenge, invent, and pivot their business model in an easy way.

All participants were divided into 2 groups to work on solutions toward the challenge: “Waste Management, recycling and utilization in Shanghai Lingang?” The experts have given lots of advice and guidance to the groups.
