Abstract Nowadays, biomass resources are the best choice to replace fossil resources. Energy development in biomass is mainly through pyrolysis of biomass. At present, no one has estimated how much biomass energy there is for a country. In this article, taking corn as an example, China as the production country, the potential biomass resources in China are speculated, in which Lignocellulose is the main experimental biomass and pyrolyzed to obtain biomass energy. The most common method of biomass energy conversion is isothermal conversion. The first-order reaction model is used for kinetic analysis of the conversion. The sample is subjected to powder falling pyrolysis at 480 degrees. In order to overcome the regional differences in China, the data of 30 degrees north latitude are used. Finally, the reaction time and the total amount of biomass energy available for development and utilization in China in 2020 are obtained.

The Beijing-Tianjin-Hebei region has abundant biomass resources, which are difficult to collect and thus are underutilized. However, the potential estimation of biomass energy can result in a comprehensive understanding of bioenergy resources in order to establish a technology roadmap for the region’s bioenergy development. Therefore, it is essential to estimate the potential of Beijing-Tianjin-Hebei biomass resources and bioenergy utilization. In this paper, the amount of main biomass resources for possible energy use and bioenergy utilization are calculated based on a statistical data estimation method for crop residues; human, poultry, and livestock manure; and municipal solid wastes. On the basis of biomass resources and bioenergy utilization potential, the technology roadmap is established. The results show that the amount for available biomass energy use is unevenly distributed in the Beijing-Tianjin-Hebei region, and the largest amount of resources is crop residues (36.52 million tons or 18.26 million tons coal equivalent). The biogas from human, poultry, and livestock manure and densified solids from crop residue technology roadmap is suitable for the Beijing-Tianjin-Hebei region.

The alignment of the Greek national legislation with the corresponding EU legislation has enhanced the national efforts to pursue renewable Combined Heat and Power (CHP) projects. The scope of the present study has been the identification of the available biomass resources and the assessment of their potential. In this paper, we present the results from the administrative regions of Crete, Thessaly, and Peloponnese. The levels of lignocellulosic biomass in Greece are estimated to be 2,132,286 tonnes on an annual basis, values that are very close to the cases of other Mediterranean countries like Italy and Portugal. In respect to the total agricultural residues, Crete produces 1,959,124 tonnes/year and Thessaly produces 1,759,457 tonnes/year. The most significant streams are identified to be olive pits, olive pruning, and cotton ginning remnants, with more than 100,000 tonnes/year each. In the latter part of this manuscript, a case study is presented for the development of a CHP gasification facility in Messenia. The biomass energy potential of the area is very promising, with about 3,800,000 GJ/year. The proposed small-scale gasification technology is expected to utilize 7956 tonnes of biomass per year and to produce 6630 MWh of electricity and 8580 MWh of thermal energy.

Pyrolysis Of Biomass

Biomass such as agriculture waste and urban waste are enormous potency as energy resources instead of enviromental problem. organic waste can be converted into energy in the form of liquid fuel, solid, and syngas by using of pyrolysis technique. Pyrolysis process can yield higher liquid form when the process can be drifted into fast and flash response. It can be solved by using microwave heating method. This research is started from developing an experimentation laboratory apparatus of microwave-assisted pyrolysis of biomass energy conversion system, and conducting preliminary experiments for gaining the proof that this method can be established for driving the process properly and safely. Modifying commercial oven into laboratory apparatus has been done, it works safely, and initial experiments have been carried out, process yields bio-oil and charcoal shortly, several parameters are achieved. Some further experiments are still needed for more detail parameters. Theresults may be used to design small-scale continuous model of productionsystem, which then can be developed into large-scale model that applicable for comercial use.

Solid Biomass

Conventional energy sources often do not fully satisfy the needs of a modern economy, especially given the climate changes associated with them. These issues should be addressed by diversification of energy generation, including the development of renewable energy sources (RES). Solid biomass will play a major part in the process in Poland. The function of rural areas, along with a well-developed agricultural and forest economy sector, will be a key aspect in this as these areas are suitable for solid biomass acquisition in various ways. This study aimed to determine the solid biomass energy potential in the commune of Goworowo to illustrate the potential in the smallest administrative units of Poland. This research determined the environmental and natural conditions in the commune, which helped to identify the crucial usable solid biomass resources. The total energy potential of solid biomass resources in the commune of Goworowo amounted to 97,672 GJ y−1. The highest potential was accumulated in straw surplus (37,288 GJ y−1) and the lowest was in wood from roadside maintenance (113 GJ y−1). This study showed that rural areas could soon play a significant role in obtaining solid biomass, and individual communes could become spaces for the diversification of energy feedstock.

Ecosystem services management should often expect to deal with non-linearities due to trade-offs and synergies between ecosystem services (ES). Therefore, it is important to analyze long-term trends in ES development and utilization to understand their responses to climate change and intensification of human activities. In this paper, the region of Uxin in Inner Mongolia, China, was chosen as a case study area to describe the spatial distribution and trends of 5 ES indicators. Changes in relationships between ES and driving forces of dynamics of ES relationships were analyzed for the period 1979–2016 using a stepwise regression. We found that: the magnitude and directions in ES relationships changed during this extended period; those changes are influenced by climate factors, land use change, technological progress, and population growth.

ABSTRACTThe The increasingly difficult economic conditions require educational institutions at the tertiary level to develop a model for collecting funds from the community, one of which is through cash waqf. Airlangga University already has a model of developing and utilizing campus-based cash waqf. So with this waqf solution the community can be helped especially by students to continue their education. From here the authors are encouraged to conduct research on "Models of Development and Utilization of Cash Waqf for Higher Education (Case Study of Waqf Amerta Airlangga.".With the formulation of the problem: first, How to use cash waqf for higher education in Amerta Airlangga Waqf. Second, how to model the development of cash waqf in Amerta Airlangga. The method of this study used qualitative-descriptive because the data was qualitative, the data was not quantitative which used statistic. Practically, the data collection used three methods, they were: interview, observation, and documentation.Based on the results of research in Waqf Amerta Airlangga, it is known that the Community donated funds to the Waqf Amerta Airlangga through PUSPAS which is divided into two types, namely non-endowment social donations and endowment donations. Then some of the non-waqf funds were directly put into social donation accounts which could be directly utilized for the Airlangga University PUSPAS program, by 85%. While the other 15% is for the operations of PUSPAS Airlangga University. The Waqf Fund through the Amerta Endowments program will be managed separately for the fund as an investment in a number of portfolios. Key Words : Development and Utilization Model, Cash Waqf, Higher Education
