Topic 1: Bioenergy Development in China

Blas MOLA-YUDEGO, Xiaoqian XU

Summary

Bioenergy sources in China generally are from three aspects, agricultural sources, forestry sources and others. This lecture is to review bioenergy development in recent years, and detailed information is explained by using rural terms in Shaanxi province. Following aspects are to introduce: 1) Biomass resources, direct and indirect uses; 2) Prevalent bioenergy technologies; 3) National bioenergy projects and small projects at households level; 4) Bioenergy potential; 5) Bioenergy development dilemma.

Topic 2: Bioenergy Development in Sweden

Blas MOLA-YUDEGO, Xiaoqian XU

Summary

Establishing biomass plantation for energy use may provide many opportunities to ecosystem services. Willow plantation as one alternative of fast-growing plantation for energy use has been established in Sweden since last decades. Understanding how energy crop plantation works as well as the concept of “win-win” from different stakeholders will help achieve the goals in ecosystem services. In this topic, we will discuss: 1) basic information of biomass plantation system; 2) how to establish fast-growing plantation by using willow plantation as the example; 3) the advantages of using fast-growing plantation and the disadvantages of using fast-growing plantation.

Reflections

What are direct and indirect energy uses for lignocellulosic biomass?

Which type/types of biomass is/are prevalent in your home country/region?

List at least five factors which related to biomass production and explain why. 


[These questions may help the students to focus and reflect on the topic contents. They do not require to be submitted as an assignment and are not to be evaluated.]

Objectives

The main objectives of this session are:

  • To have an overview of bioenergy development in China and Sweden
  • To know the perspective from stakeholders in rural areas of China
  • To know the biomass plantation establishment in Sweden during recent 30 years
