Circular Economy (CE) refers to all the activities of reduce, reuse and recycle (3R) in production, circulation, and consumption. It is an important route to achieving a resource-saving and environmental friendly society. Waste to energy or energy products contributes greatly to CE. How to choose energy or proper energy products strategically to achieve both environmentally and economically satisfied CE? Some scientists performed LCA or LCO (Life cycle optimization) on different energy products to develop sustainable business model for choosing proper energy products. Presently, WtE plants are widely available. However, the income or subsidies of WtE plants have been declining; while the energy products other than heat and electric power are very few, except for some limited experiences on producing oil from homogeneous wastes such as waste plastics and tires. This raises the question of what kind of energy products should be focused in future?

Some of the questions that will be discussed with experts from Asia, Europe, America and other areas include:

  • What kind of energy products should be recovered from waste treatment from both ecological and economic point of views?
  • What are the barriers for recovering value-added energy products from wastes?
  • Syngas, H2, oil, CH4, SAF, methanol etc., which are the proper energy products to achieve satisfied CE from waste management?
  • The tools to decide the proper CE mode (resources or energy recovery) for a specified scenario?
