The paper presents a review of the energy potential of different types of biomass residues in agriculture and forestry, and actual state of biomass energy utilization in Serbia. The estimated values of annual energy potential are: about 1.7?10 6 toe (ton of oil equivalent) in biomass residues in agriculture, comprising crop farming, fruit growing, viniculture and stock breeding, and about 1 million toe of biomass from forestry, including different biomass residues and fuel wood. The total annual biomass energy potential of about 2.7?10 6 toe represents 40% of the total coal energy production in Serbia. Towns located in agricultural regions and in regions rich in forest can satisfy their energy demand for centralized heading systems with biomass residues from the territory of their own municipality. With appropriate energy policy, information campaign, research activities and general regulation in the field of biomass energy utilization, the share of biomass energy consumption in total energy balance can be significantly increased.

Nowadays, renewable energy utilization plays a key role in developing countries to fulfill the additional energy requirements of a country and reduce dependency on fossil fuels and traditional biomass consumption. As Myanmar has an agriculture-based economy and 48% of forest-cover (32.2 million hectares); biomass is one of the major renewable energy sources, contributing around 50% of total energy consumption. Therefore, the study aimed to highlight the available biomass sources and energy potential for the energy sector in Myanmar. In order to achieve the aim, the study collated the types, quantity and qualities of biomass resources, and energy utilization around Myanmar. Besides, the study synthesized and evaluated the energy potential of the major biomass resources coming from the agriculture sector, forest sector, livestock and poultry sector, and municipal sector. It was estimated that the total energy potential of the major biomass sources amounted to approximately 15.19 million tons of oil equivalent (Mtoe) in 2005 and 17.29 Mtoe in 2017, respectively. The unexploited biomass energy potential around the country was estimated to be nearly 50% higher than that of the projected biomass energy utilization during 2015–2019. Finally, the study concluded with recommendations to provide the future sustainable development of biomass energy in Myanmar.

AbstractThe global demand for sustainable energy is increasing due to urbanization, industrialization, population, and developmental growth. Transforming the large quantities of biomass resources such as agro-residues/wastes could raise the energy supply and promote energy mix. Residues of biomass instituted in the rural and industrial centers are enormous, and poor management of these residues results in several indescribable environmental threats. The energy potential of these residues can provide job opportunities and income for nations. The generation and utilization of dissimilar biomass as feedstock for energy production via densification could advance the diversity of energy crops. An increase in renewable and clean energy demand will likely increase the request for biomass residues for renewable energy generation via densification. This will reduce the environmental challenges associated with burning and dumping of these residues in an open field. Densification is the process of compacting particles together through the application of pressure to form solid fuels. Marketable densification is usually carried out using conventional pressure-driven processes such as extrusion, screw press, piston type, hydraulic piston press, roller press, and pallet press (ring and flat die). Based on compaction, densification methods can be categorized into high-pressure, medium-pressure, and low-pressure compactions. The common densification processes are briquetting, pelletizing, bailing, and cubing. They manufacture solid fuel with desirable fuel characteristics—physical, mechanical, chemical, thermal, and combustion characteristics. Fuel briquettes and pellets have numerous advantages and applications both in domestic and industrial settings. However, for biomass to be rationally and efficiently utilized as solid fuel, it must be characterized to determine its fuel properties. Herein, an overview of the densification of biomass residues as a source of sustainable energy is presented.

Due to the tremendous amount of palm biomass residues produced during the palm oil extraction from fresh fruit bunch (FFB), it is inevitable to harness these biomass energy sources to cope with the depletion of fossil fuels and increase in global energy demand scenarios. Densification is one of the favourable techniques to improve the storage and transportation of biomass fuels in order to prevent dumped areas adjacent to palm mills and to prevent from becoming another waste product. This article reviews comprehensively on how type of palm biomass, compaction pressure and temperature, binder, pre- and post-treatments affect the physical and combustion properties of the palm biomass briquettes produced. Based on the previous researches, generally it can be said that the type of palm biomass, the compaction pressure and temperature, and type of binder affect both the physical and combustion performance of densified palm biomass. However, the effect of particle size could be observed only on the physical characteristics of densified products, whereas the effect on the combustion properties remains unclear. In addition, treatments such as pyrolysis, dry and wet torrefaction (hydrothermal treatment), and steam explosion have potential to be applied during briquette production in order to improve the combustion properties. In this review article, it is also suggested that the combination of densification and followed by wet torrefaction will enhance the combustion properties of palm biomass briquettes.

The study was conducted to investigate the energy efficiency of traditional and improved cooking stove, potential energy conservation using improved stove and overall environmental impacts of those stoves at Thaipara of Magura district in Bangladesh. In the study area, almost 100% of the households use biomass as their cooking fuel in traditional stoves. Questionnaire Survey (QS) was conducted to fulfill the research objectives. The result of the study showed that total biomass energy consumption is 14897 GJ per year, whereas, the per capita cooking energy consumption is about 4.82 GJ per year. The results also revealed that biomass: fuel wood, dung and crop residues are the 100% sources of the total energy used in the cooking sectors. The combination of high demand aggravated by low use efficiency has contributed to deforestation, rural poverty and the energy shortage in the study village. Results of the study stated that by introducing improved stove with higher level of efficiency, well ventilation and using good quality of fuel can reduce the harmful impacts of cooking energy utilization and cooking systems on environment significantly. In this regard, formulation and implementation of a nationwide high efficiency cooking stove dissemination program would be very promising for cooking energy conservation at rural sectors. Environ.

Energy has been a key factor in economic development. Myanmar has considerable indigenous energy potential, which could meet domestic demand in long term if properly managed. This paper documents the current status of energy demand and supply in Myanmar, and analyses the characteristics of energy mix, and concludes that (1) Myanmar is confronted with a pressing energy demand with the rapid development of economy; (2) Myanmar’s energy production mix is dominated by oil, gas and hydropower, and the consumption structure is dominated by biomass; (3) the shortage of energy is mostly due to its unbalanced energy mix and irrational notion for energy utilization. In order to solve the serious problems between energy demand and supply, it is necessary for Myanmar to build more responsible hydropower projects, to optimize the national grid and to make more reliable and practicable energy plans.

Biomass energy potential is addressed to be the most promising among the renewable energy sources, due to its spread and availability worldwide. Apart form that, biomass has the unique advantage among the rest of renewable energy sources, to be able to provide solid, liquid, and gaseous fuels that can be stored, transported, and utilized, far away from the point of origin. For the northern region of Macedonia in Greece, biomass utilization is considered to be a major issue, due to the considerably intensive regional agricultural activities. Wood by-products, fruit cores, rice husk and cotton gin waste provide a promising energy source for the region. The energy potential of the available agricultural biomass produced in the region is much enough to cover the 10% of the annual oil consumption utilized for thermal applications. However, the cost of energy utilization of biomass is considerably high due to the high cost of the logistics concerning the collection, transport, and storage of biomass. The available utilization technologies developed, to handle efficiently all different species of biomass, cover a wide technological range. One of the most promising technologies involving thermal treatment of biomass and the production of a gaseous fuel (biogas) for industrial heat applications and electricity production, is the thermo chemical conversion. In the present work, an investigation concerning biomass potential for energy production in the region of central Macedonia in Greece, utilizing several locally produced biomass species, is conducted. Emphasis is put on the energy utilization of agricultural by-products and residues. Agricultural sector is of great importance due to the considerably intensive agricultural activities in the region of Central Macedonia. .

Development of the world economy requires energy supply, which under stable growth must be based on alternative energy resources. Bioenergy is an integral part of energy security supply in volatile countries. It can satisfy a considerable part of energy demand of agribusinesses and other companies as well as facilitate problem-shooting in energy, ecological and social sectors in some regions. Enhancing bioenergy in Ukraine is one of the strategic ways in the development of the alternative energy sector, taking into account high volatility of the country and significant potential of biomass available for energy production. This research intends to determine conditions and mechanisms of development and functioning of bioenergy clusters based on preliminary specification of the bioenergy potential of the territories, taking into account modern marketing approaches. This article contains evaluation of the bioenergy production growth in countries such as China, Germany, France, the USA, Canada, Brazil and Ukraine. The feasibility of the cluster approach for Ukrainian bioenergy development has been proved. In order to combine Ukrainian regions according to all types of energy resources the authors applied the method of clustering analysis. The key point of the method implies that, based on the given set of indicators which are defined as the main characteristics of the object, every object of the population belongs to a similar class. Therefore, in order to study the efficiency of usage of bioenergy resources in a particular region, it is necessary to classify a set of indicators to identify standard forms. To systemize Ukrainian regions, the Isodata algorithm Isodata, based on the types of the economic and energy potential of biomass, is taken into account. To implement the analysis, the following indicators are considered: the biomass energy potential of primary cell waste, the biomass energy potential of trimming, the biomass energy potential of refining, the energy potential of wooden biomass, the mold biomass potential, the energy potential of bioenergy crops, the corn energy potential (biogas). Market players organize groups with regard to their industries, territories and other factors, namely clusters which are likely to become effective tools in while carrying out scale projects under tough competition. In the minor energy sector cooperation between research and manufacturing enterprises, which satisfies energy needs both of cities and individual customers, is growing. This approach perfectly meets all requirements of the regional development of Ukrainian bioenergy. The main goal of bioenergy clusters is to develop competitive advantages of regions by increasing all types of biomass and biofuel production. This implies the following priorities: creation of a database of agribusiness enterprises, which potentially are members of the cluster and corresponding infrastructure, establishment of marketing communications in order to inform members and potential investors about bioenergy advantages, introduction of regional databases by means of webpages, newsletters, public discussions etc., enhanced vocational training of bioenergy industry employees and investment attraction to finance bioenergy projects. As a result, the authors of the paper propose a classification of Ukrainian regions based on the indicators of the economic energy potential of wastes and energy crops in agribusinesses, which is the basis for cluster formation. Vinnytsia, Kyiv, Poltava, Sumy, Khmelnitsky and Chernihiv regions refer to the first type with the biggest bioenergy potential, which makes it possible to create 2 energy clusters by combining central-west and north-east regions. Such a methodology gives an opportunity to satisfy the needs of the regions and districts which need additional energy resources taken from own biomass. Priority tasks of the bioenergy cluster include: development of the database of agribusiness entities which potentially are the cluster members and corresponding infrastructure, informing members and investors about bioenergy benefits, creation of the regional information database identifying the resources, capacity and the transport system, vocational training, investment attraction in order to implement bioenergy projects. Based on clusters, economic relations build up a competitive and sound investment climate to support the economy, which, in turn, provides high living standards. The authors have defined the procedure for exercising the cluster initiative and determined the structure of marketing support for cluster projects.
