Biomass Market in Japan: Perspectives

Biomass-Power-Plant-JapanBiomass is being increasingly used in power plants in Japan as a source of fuel, particularly after the tragic accident at Fukushima nuclear power plant in 2011.  Palm kernel shell (PKS) has emerged as a favorite choice of biomass-based power plants in the country. Most of these biomass power plants use PKS as their energy source, and only a few operate with wood pellets. Interestingly, most of the biomass power plants in Japan have been built after 2015.

Palm Kernel Shells

Palm Kernel Shell is generating very good traction as a renewable energy resource and biomass commodity in Japan. This is because PKS is the cheapest biomass fuel and is available in large quantities across Southeast Asia. PKS, a biomass waste generated by palm oil mills, can be found in plentiful quantities in Indonesia, Malaysia and Thailand.

PKS must meet the specifications before being exported to Japan. Some key specifications for PKS exports are: moisture content, calorific value and impurities or contaminants (foreign materials). All three variables must meet a certain level to achieve export quality. Japanese markets or their consumers generally require contaminants from 0.5 to 2%, while European 2% – 3%. Japan usually buys with a volume of 10,000 tonnes per shipment, so PKS suppliers must prepare a sufficient stockpile of the PKS. The location of PKS stockpile that is closest to the seaport is the ideal condition to facilitate transportation of shipment.

Wood Pellets

Wood pellets are mostly produced in from wood waste such as sawdust, wood shaving, plywood waste, forestry residues and related materials. The development potential for quantity enlargement is also possible with energy plantations. Technically the properties of wood pellets are not much different from the PKS.

Wood pellet price is more expensive than PKS. Wood pellet production process is more complex than PKS, so wood pellet is categorized as finished product. The quality of wood pellet is generally viewed from its density, calorific value and ash content. Indonesia wood pellet export is not as big as PKS, it is also because of the limited producers of wood pellet itself. Japan buys wood pellets from Indonesia mostly for testing on their biomass power plants. Shipping or export by container is still common in wood pellet sector because the volume is still small. Currently, the world’s leading producer of wood pellets come from North America and Scandinavia. Even for Indonesia itself wood pellet is a new thing, so its production capacity is also not big.

Future Perspectives

For a short-term solution, exporting PKS is a profitable business.  Wood pellets with raw materials from energy plantations by planting the legume types such as calliandra are medium-term solutions to meet biomass fuel needs in Japan.  Torrefaction followed by densification can be a long-term orientation. Torrified pellet is superior to wood pellet because it can save transportation and facilitate handling, are hydrophobic and has higher calorific value.

 

Energy Access to Refugees

refugee-camp-energyThere is a strong link between the serious humanitarian situation of refugees and lack of access to sustainable energy resources. According to a 2015 UNCHR report, there are more than 65.3 million displaced people around the world, the highest level of human displacement ever documented. Access to clean and affordable energy is a prerequisite for sustainable development of mankind, and refugees are no exception. Needless to say, almost all refugee camps are plagued by fuel poverty and urgent measure are required to make camps livable.

Usually the tragedy of displaced people doesn’t end at the refugee camp, rather it is a continuous exercise where securing clean, affordable and sustainable energy is a major concern. Although humanitarian agencies are providing food like grains, rice and wheat; yet food must be cooked before serving. Severe lack of modern cook stoves and access to clean fuel is a daily struggle for displaced people around the world. This article will shed some light on the current situation of energy access challenges being faced by displaced people in refugee camps.

Why Energy Access Matters?

Energy is the lifeline of our modern society and an enabler for economic development and advancement. Without safe and reliable access to energy, it is really difficult to meet basic human needs. Energy access is a challenge that touches every aspect of the lives of refugees and negatively impacts health, limits educational and economic opportunities, degrades the environment and promotes gender discrimination issues. Lack of energy access in refugee camps areas leads to energy poverty and worsen humanitarian conditions for vulnerable communities and groups.

Energy Access for Cooking

Refugee camps receive food aid from humanitarian agencies yet this food needs to be cooked before consumption. Thus, displaced people especially women and children take the responsibility of collecting firewood, biomass from areas around the camp. However, this expose women and minors to threats like sexual harassments, danger, death and children miss their opportunity for education. Moreover, depleting woods resources cause environmental degradation and spread deforestation which contributes to climate change. Moreover, cooking with wood affects the health of displaced people.

Access to efficient and modern cook stove is a primary solution to prevent health risks, save time and money, reduce human labour and combat climate change. However, humanitarian agencies and host countries can aid camp refugees in providing clean fuel for cooking because displaced people usually live below poverty level and often host countries can’t afford connecting the camp to the main grid. So, the issue of energy access is a challenge that requires immediate and practical solutions. A transition to sustainable energy is an advantage that will help displaced people, host countries and the environment.

Energy Access for Lighting

Lighting is considered as a major concern among refugees in their temporary homes or camps. In the camps life almost stops completely after sunset which delays activities, work and studying only during day time hours. Talking about two vulnerable groups in the refugees’ camps “women and children” for example, children’s right of education is reduced as they have fewer time to study and do homework. For women and girls, not having light means that they are subject to sexual violence and kidnapped especially when they go to public restrooms or collect fire woods away from their accommodations.

Rationale For Sustainable Solutions

Temporary solutions won’t yield results for displaced people as their reallocation, often described as “temporary”, often exceeds 20 years. Sustainable energy access for refugees is the answer to alleviate their dire humanitarian situation. It will have huge positive impacts on displaced people’s lives and well-being, preserve the environment and support host communities in saving fuel costs.  Also, humanitarian agencies should work away a way from business as usual approach in providing aid, to be more innovative and work for practical sustainable solutions when tackling energy access challenge for refugee camps.

UN SDG 7 – Energy Access

The new UN SDG7 aims to “ensure access to affordable, reliable, sustainable and modern energy for all”. SDG 7 is a powerful tool to ensure that displaced people are not left behind when it comes to energy access rights. SDG7 implies on four dimensions: affordability, reliability, sustainability and modernity. They support and complete the aim of SDG7 to bring energy and lightening to empower all human around the world. All the four dimensions of the SDG7 are the day to day challenges facing displaced people. The lack of modern fuels and heavy reliance on primitive sources, such as wood and animal dung leads to indoor air pollution.

Energy access touches every aspect of life in refugee camps

Energy access touches every aspect of life in refugee camps

For millions of people worldwide, life in refugee camps is a stark reality. Affordability is of concern for displaced people as most people flee their home countries with minimum possessions and belongings so they rely on host countries and international humanitarian agencies on providing subsidized fuel for cooking and lightening. In some places, host countries are itself on a natural resources stress to provide electricity for people and refugees are left behind with no energy access resources. However, affordability is of no use if the energy provision is not reliable (means energy supply is intermittent).

Parting Shot

Displaced people need a steady supply of energy for their sustenance and economic development. As for the sustainability provision, energy should produce a consistent stream of power to satisfy basic needs of the displaced people. The sustained power stream should be greater than the resulted waste and pollution which means that upgrading the primitive fuel sources used inside the camp area to the one of modern energy sources like solar energy, wind power, biogas and other off-grid technologies.

Clean Energy Investment Forecast for 2016

renewables-investment-trendsGlobal interest in clean energy technologies reached new heights last year and 2016 promises to be another record-breaker. The year 2015 witnessed installation of more than 121 GW of renewable power plants, a remarkable increase of 30% when compared to 2014. With oil and gas prices tumbling out to unprecedented levels, 2016 should be a landmark year for all clean energy technologies. As per industry trends, solar power is expected to be the fastest-growing renewable power generation technology in 2016, closely followed by wind energy. Among investment hotspots, Asia, Africa and the Middle East will be closely watched this year.

Investment Forecast for 2016

Clean energy is rapidly becoming a part of mainstream investment portfolios all over the world. In 2016, a greater attention will be focused on renewable energy, mainly on account of the Paris Framework and attractive tax credits for clean energy investments in several countries, especially USA.

Infact, the increasing viability of clean energy is emerging as a game-changer for large-scale investors. The falling prices of renewable power (almost 10% per year for solar), coupled with slump in crude oil prices, is pulling global investors away from fossil fuel industry. At the 2016 UN Investor Summit on Climate Risk, former US vice president Al Gore said, “If this curve continues, then its price is going to fall “significantly below the price of electricity from burning any kind of fossil fuel in a few short years”.

There has been an astonishing growth in renewable generation in recent years. “A dozen years ago, the best predictors in the world told us that the solar energy market would grow by 2010 at the incredible rate of 1 GW per year,” said Gore. “By the time 2010 came around, they exceeded that by 17 times over. Last year, it was exceeded by 58 times over. This year, it’s on track to be exceeded by 68 times over. That’s an exponential curve.”

China will continue to dominate solar as well as wind energy sectors

China will continue to dominate solar as well as wind energy sectors

As per industry forecasts, China will continue its dominance of world PV market, followed closely by the US and Japan. Infact, USA is anticipated to overtake Japan as the second largest solar market this year. India, which is developing a highly ambitious solar program, will be a dark horse for cleantech investors. The top solar companies to watch include First Solar, Suntech, Canadian Solar, Trina Solar, Yingli Solar, Sharp Solar and Jinko Solar.

Morocco has swiftly become a role model for the entire MENA. The government’s target of 2GW of solar and 2GW of wind power by 2020 is progressing smoothly. As for solar, the 160MW Noor-1 CSP is already commissioned while Noor-2 and Noor-3 are expected to add a combined 350MW in 2017.

China will continue to lead the global wind energy market in 2016, and is on course to achieve its target of 200 GW of installed wind capacity by 2020. Other countries of interest in the wind sector will be Canada, Mexico, Brazil and South Africa. The major wind turbine manufacturers to watch are Siemens, Vestas, Goldwind, Gamesa and GE.

Conclusion

To sum up, the rapid growth of global renewable energy sector in the past few years is the strongest signal yet for investors and corporations to take the plunge towards green energy and low-carbon growth. As the UN chief Ban Ki-moon famously said, “It marks the beginning of the end of growth built solely on fossil fuel consumption. The once unthinkable has now become unstoppable.”

Biomass Energy in China

biomass-chinaBiomass energy in China has been developing at a rapid pace. Installed biomass power generation capacity in China increased sharply from 1.4 GW in 2006 to 8.5 GW in 2013. While the energy share of biomass remains relatively low compared to other sources of renewable energy, China plans to increase the proportion of biomass energy up to 15 percent and total installed capacity of biomass power generation to 30 GW by 2030.  In terms of impact, the theoretical biomass energy resource in China is about 5 billion tons coal equivalent, which equals 4 times of all energy consumption. As per conservative estimates, currently China is only using 5 percent of its total biomass potential.

According to IRENA, the majority of biomass capacity is in Eastern China, with the coastal province of Shandong accounting for 14 percent of the total alone. While the direct burning of mass for heat remains the primary use of biomass in China, in 2009, composition of China’s biomass power generation consisted in 62 percent of straw direct-fired power generation and 29 percent of waste incineration, with a mix of other feedstock accounting for the remaining 9 percent.

Biomass Resources in China

Major biomass resources in China include waste from agricultural, forestry, industrial, animal and sewage, and municipal solid waste. While the largest contributing sources are estimated to be residues from annual crop production like wheat straw, much of the straw and stalk are presently used for cooking and heating in rural households at low efficiencies. Therefore, agricultural residues, forestry residues, and garden waste were found to be the most cited resources with big potential for energy production in China.

Agricultural residues are derived from agriculture harvesting such as maize, rice and cotton stalks, wheat straw and husks, and are most available in Central and northeastern China where most of the large stalk and straw potential is located. Because straw and stalks are produced as by-products of food production systems, they are perceived to be sustainable sources of biomass for energy that do not threaten food security. Furthermore, it is estimated that China produces around 700 Mt of straw per year, 37 percent of which is corn straw, 28 percent rice, 20 percent wheat and 15 percent from various other crops. Around 50 percent of this straw is used for fertilizers, for which 350 Mt of straw is available for energy production per year.

Biomass resources are underutilized across China

Biomass resources are underutilized across China

Forestry residues are mostly available in the southern and central parts of China. While a few projects that use forestry wastes like tree bark and wood processing wastes are under way, one of the most cited resources with analyzed potential is garden waste. According to research, energy production from garden waste biomass accounted for 20.7 percent of China’s urban residential electricity consumption, or 12.6 percent of China’s transport gasoline demand in 2008.

Future Perspectives

The Chinese government believes that biomass feedstock should neither compete with edible food crops nor cause carbon debt or negative environmental impacts. As biomass takes on an increasing significant role in the China’s national energy-mix, future research specific to technology assessment, in addition to data collection and supply chain management of potential resources is necessary to continue to understand how biomass can become a game-changer in China’s energy future.

Green SMEs: Catalyst for Green Economy

Green SMEsWith ‘green’ being the buzzword across all industries, greening of the business sector and development of green skills has assumed greater importance all over the world. SMEs, startups and ecopreneurs are playing a vital role in the transition to a low-carbon economy by developing new green business models for different industrial sectors. Infact, young and small firms are emerging as main drivers of radical eco-innovation in the industrial and services sectors.

What are Green SMEs

Green SMEs adopt green processes and/or those producing green goods using green production inputs. A judicious exploitation of techno-commercial opportunities and redevelopment of business models, often neglected by established companies, have been the major hallmarks of green SMEs. For example, SMEs operating in eco-design, green architecture, renewable energy, energy efficiency and sustainability are spearheading the transition to green economy across a wide range of industries. The path to green economy is achieved by making use of production, technology and management practices of green SMEs.

Categories of Green Industries

Environmental Protection Resource Management
Protection of ambient air Water management
Protection of climate Management of forest resources
Wastewater management Management of flora and fauna
Waste management Energy management
Noise and vibration abatement Management of minerals
Protection of biodiversity and landscape Eco-construction
Protection against radiation Natural resource management activities
Protection of soil, groundwater and surface water Eco-tourism
Environmental Monitoring and Instrumentation Organic agriculture
Research and Development Research and Development

Key Drivers

The key motivations for a green entrepreneur are to exploit the market opportunity and to promote environmental sustainability. A green business help in the implementation of innovative solutions, competes with established markets and creates new market niches. Green entrepreneurs are a role model for one and all as they combine environmental performance with market targets and profit outcomes, thus contributing to the expansion of green markets.

Some of the popular areas in which small green businesses have been historically successful are renewable energy production (solar, wind and biomass), smart metering, building retrofitting, hybrid cars and waste recycling.  As far as established green industries (such as waste management and wastewater treatment) are concerned, large companies tend to dominate, however SMEs and start-ups can make a mark if they can introduce innovative processes and systems. Eco-friendly transformation of existing practices is another attractive pathway for SMEs to participate in the green economy.

The Way Forward

Policy interventions for supporting green SMEs, especially in developing nations, are urgently required to overcome major barriers, including knowledge-sharing, raising environmental awareness, enhancing financial support, supporting skill development and skill formation, improving market access and implementing green taxation. In recent decades, entrepreneurship in developing world has been increasing at a rapid pace which should be channeled towards addressing water, energy, environment and waste management challenges, thereby converting environmental constraints into business opportunities.

Biomass Energy in Vietnam

Vietnam is one of the few countries having a low level of energy consumption in the developing world with an estimated amount of 210 kg of oil equivalent per capita/year. Over half of the Vietnamese population does not have access to electricity. Vietnam is facing the difficult challenge of maintaining this growth in a sustainable manner, with no or minimal adverse impacts on society and the environment.

Being an agricultural country, Vietnam has very good biomass energy potential. Agricultural wastes are most abundant in the Mekong Delta region with approximately 50% of the amount of the whole country and Red River Delta with 15%. Major biomass resources includes rice husk from paddy milling stations, bagasse from sugar factories, coffee husk from coffee processing plants in the Central Highlands and wood chip from wood processing industries. Vietnam has set a target of having a combined capacity of 500 MW of biomass power by 2020, which is raised to 2,000 MW in 2030.

Rice husk and bagasse are the biomass resources with the greatest economic potential, estimated at 50 MW and 150 MW respectively. Biomass fuels sources that can also be developed include forest wood, rubber wood, logging residues, saw mill residues, sugar cane residues, bagasse, coffee husk and coconut residues. Currently biomass is generally treated as a non-commercial energy source, and collected and used locally. Nearly 40 bagasse-based biomass power plants have been developed with a total designed capacity of 150 MW but they are still unable to connect with the national grid due to current low power prices. Five cogeneration systems selling extra electricity to national grid at average price of 4UScents/kWh.

Biogas energy potential is approximately 10 billion m3/year, which can be collected from landfills, animal excrements, agricultural residues, industrial wastewater etc. The biogas potential in the country is large due to livestock population of more than 30 million, mostly pigs, cattle, and water buffalo. Although most livestock dung already is used in feeding fish and fertilizing fields and gardens, there is potential for higher-value utilization through biogas production. It is estimated that more than 25,000 household biogas digesters with 1 to 50 m3, have been installed in rural areas. The Dutch-funded Biogas Program operated by SNV Vietnam constructed some 18,000 biogas facilities in 12 provinces between 2003 and 2005, with a second phase (2007-2010) target of 150,000 biogas tanks in both rural and semi-urban settings.

Municipal solid waste is also a good biomass resource as the amount of solid waste generated in Vietnam has been increasing steadily over the last few decades. In 1996, the average amount of waste produced per year was 5.9 million tons per annum which rose to 28 million tons per in 2008 and expected to reach 44 million tons per year by 2015.

Overview of Biomass Energy Systems

Biomass is a versatile energy source that can be used for production of heat, power, transport fuels and biomaterials, apart from making a significant contribution to climate change mitigation. Currently, biomass-driven combined heat and power, co-firing, and combustion plants provide reliable, efficient, and clean power and heat. Feedstock for biomass energy plants can include residues from agriculture, forestry, wood processing, and food processing industries, municipal solid wastes, industrial wastes and biomass produced from degraded and marginal lands.

The terms biomass energy, bioenergy and biofuels cover any energy products derived from plant or animal or organic material. The increasing interest in biomass energy and biofuels has been the result of the following associated benefits:

  • Potential to reduce GHG emissions.
  • Energy security benefits.
  • Substitution for diminishing global oil supplies.
  • Potential impacts on waste management strategy.
  • Capacity to convert a wide variety of wastes into clean energy.
  • Technological advancement in thermal and biochemical processes for waste-to-energy transformation.

Biomass can play the pivotal role in production of carbon-neutral fuels of high quality as well as providing feedstocks for various industries. This is a unique property of biomass compared to other renewable energies and which makes biomass a prime alternative to the use of fossil fuels. Performance of biomass-based systems for heat and power generation has been already proved in many situations on commercial as well as domestic scales.

Biomass energy systems have the potential to address many environmental issues, especially global warming and greenhouse gases emissions, and foster sustainable development among poor communities. Biomass fuel sources are readily available in rural and urban areas of all countries. Biomass-based industries can provide appreciable employment opportunities and promote biomass re-growth through sustainable land management practices.

The negative aspects of traditional biomass utilization in developing countries can be mitigated by promotion of modern waste-to-energy technologies which provide solid, liquid and gaseous fuels as well as electricity as shown. Biomass wastes can be transformed into clean and efficient energy by biochemical as well as thermochemical technologies.

The most common technique for producing both heat and electrical energy from biomass wastes is direct combustion. Thermal efficiencies as high as 80 – 90% can be achieved by advanced gasification technology with greatly reduced atmospheric emissions. Combined heat and power (CHP) systems, ranging from small-scale technology to large grid-connected facilities, provide significantly higher efficiencies than systems that only generate electricity.  Biochemical processes, like anaerobic digestion and sanitary landfills, can also produce clean energy in the form of biogas and producer gas which can be converted to power and heat using a gas engine.

In addition, biomass wastes can also yield liquid fuels, such as cellulosic ethanol, which can be used to replace petroleum-based fuels. Cellulosic ethanol can be produced from grasses, wood chips and agricultural residues by biochemical route using heat, pressure, chemicals and enzymes to unlock the sugars in cellulosic biomass. Algal biomass is also emerging as a good source of energy because it can serve as natural source of oil, which conventional refineries can transform into jet fuel or diesel fuel.

Recycling and Waste-to-Energy Prospects in Saudi Arabia

recycling-Saudi-ArabiaThe Kingdom of Saudi Arabia produces around 15 million tons of municipal solid waste (MSW) each year with average daily rate of 1.4 kg per person. With the current growing population (3.4% yearly rate), urbanization (1.5% yearly rate) and economic development (3.5% yearly GDP rate), the generation rate of MSW will become double (30 million tons per year) by 2033. The major ingredients of Saudi Arabian garbage are food waste (40-51 %), paper (12-28 %), cardboard (7 %), plastics (5-17 %), glass (3-5 %), wood (2-8 %), textile (2-6 %), metals (2-8 %) etc. depending on the population density and urban activities of that area.

In Saudi Arabia, MSW is collected and sent to landfills or dumpsites after partial segregation and recycling. The major portion of collected waste is ends up in landfills untreated. The landfill requirement is very high, about 28 million m3 per year. The problems of leachate, waste sludge, and methane and odor emissions are occurring in the landfills and its surrounding areas due to mostly non-sanitary or un-engineered landfills. However, in many cities the plans of new sanitary landfills are in place, or even they are being built by municipalities with capturing facilities of methane and leachate.

Recycling Prospects in Saudi Arabia

The recycling of metals and cardboard is the main waste recycling practice in Saudi Arabia, which covers 10-15% of the total waste. This recycling practice is mostly carried out by informal sector. The waste pickers or waste scavengers take the recyclables from the waste bins and containers throughout the cities. The waste recycling rate often becomes high (upto 30% of total waste) by waste scavengers in some areas of same cities. The recycling is further carried out at some landfill sites, which covers upto 40% of total waste by the involvement of formal and informal sectors.

The recycled products are glass bottles, aluminum cans, steel cans, plastic bottles, paper, cardboard, waste tire, etc. depending on the area, available facilities and involved stakeholders. It is estimated that 45 thousand TJ of energy can be saved by recycling only glass and metals from MSW stream. This estimation is based on the energy conservation concept, which means xyz amount of energy would be used to produce the same amount of recyclable material.

Waste-to-Energy Potential in Saudi Arabia

The possibilities of converting municipal wastes to renewable energy are plentiful. The choice of conversion technology depends on the type and quantity of waste (waste characterization), capital and operational cost, labor skill requirements, end-uses of products, geographical location and infrastructure. Several waste to energy technologies such as pyrolysis, anaerobic digestion (AD), trans-esterification, fermentation, gasification, incineration, etc. have been developed. WTE provides the cost-effective and eco-friendly solutions to both energy demand and MSW disposal problems.

As per conservative estimates, electricity potential of 3 TWh per year can be generated, if all of the KSA food waste is utilized in biogas plants. Similarly, 1 and 1.6 TWh per year electricity can be generated if all the plastics and other mixed waste (i.e. paper, cardboard, wood, textile, leather, etc.) of KSA are processed in the pyrolysis, and refuse derived fuel (RDF) technologies respectively.

Conclusion

Waste management issues in Saudi Arabia are not only related to water, but also to land, air and the marine resources. The sustainable integrated solid waste management (SWM) is still at the infancy level. There have been many studies in identifying the waste related environmental issues in KSA. The current SWM activities of KSA require a sustainable and integrated approach with implementation of waste segregation at source, waste recycling, WTE and value-added product (VAP) recovery. By 2032, Saudi government is aiming to generate about half of its energy requirements (about 72 GW) from renewable sources such as solar, nuclear, wind, geothermal and waste-to-energy systems.

Biomass Energy Scenario in ASEAN Countries

The rapid economic growth and industrialization in ASEAN region is characterized by a significant gap between energy supply and demand. The energy demand in the region is expected to grow rapidly in the coming years which will have a profound impact on the global energy market. In addition, the region has many locations with high population density, which makes public health vulnerable to the pollution caused by fossil fuels.

Another important rationale for transition from fossil-fuel-based energy systems to renewable ones arises out of observed and projected impacts of climate change. Due to the rising share of greenhouse gas emissions from Asia, it is imperative on all Asian countries to promote sustainable energy to significantly reduce GHGs emissions and foster sustainable energy trends. Rising proportion of greenhouse gas emissions is causing large-scale ecological degradation, particularly in coastal and forest ecosystems, which may further deteriorate environmental sustainability in the region.

The reliance on conventional energy sources can be substantially reduced as the region is one of the leading producers of biomass resources in the world. The energy generating capacity of biomass-based CHP plants is comparatively much higher than other alternative energy technologies like solar, wind and geothermal energy. In addition, solar and wind projects are confined to remote rural electrification and community centres, where the required installed capacity is low. On the other hand, biomass-based cogeneration plants can generate higher capacities of electrical and heat energy that could benefit an entire township and industries in the immediate area.

Southeast Asia, with its abundant biomass resources, holds a strategic position in the global biomass energy atlas. There is immense potential of biomass energy in ASEAN countries due to plentiful supply of diverse forms of wastes such as agricultural residues, woody biomass, animal wastes, municipal solid waste, etc. ASEAN region is a big producer of wood and agricultural products which, when processed in industries, produces large amounts of biomass residues. According to conservative estimates, the amount of biomass residues generated from sugar, rice and palm oil mills is more than 200-230 million tons per year which corresponds to cogeneration potential of 16-19 GW. Woody biomass is a good energy resource due to presence of large number of forests and wood processing industries in the region.

The prospects of biogas power generation are also high in the region due to the presence of well-established food-processing and dairy industries. Another important biomass resource is contributed by municipal solid wastes in heavily populated urban areas.  In addition, there are increasing efforts from the public and private sectors to develop biomass energy systems for efficient biofuel production, e.g. bio-diesel from palm oil. The rapid economic growth and industrialization in the region has accelerated the drive to implement the latest biomass energy technologies in order to tap the unharnessed potential of biomass resources, thereby making a significant contribution to the regional energy mix.

Bioenergy Developments in Malaysia

Malaysia is blessed with abundant renewable sources of energy, especially biomass and solar. Under the Eighth Malaysian Plan, renewable energy was added in the energy mix to unveil a Five-Fuel Strategy to achieve 5 percent contribution by 2005.

Among the various sources of renewable energy, bioenergy seems to be the most promising option for Malaysia. The National Biofuel Policy, launched in 2006 encourages the use of environmentally friendly, sustainable and viable sources of biomass energy. Under the Five Fuel Policy, the government of Malaysia has identified biomass as one of the potential renewable energy. Malaysia produces atleast 168 million tonnes of biomass, including timber and oil palm waste, rice husks, coconut trunk fibres, municipal waste and sugar cane waste annually. Being a major agricultural commodity producer in the region Malaysia is well positioned amongst the ASEAN countries to promote the use of biomass as a renewable energy source.

Malaysia has been one of the world’s largest producers and exporters of palm oil for the last forty years. The Palm Oil industry, besides producing Crude Palm Oil (CPO) and Palm Kernel Oil, produces Palm Shell, Press Fibre, Empty Fruit Bunches (EFB), Palm Oil Mill Effluent (POME), Palm Trunk (during replanting) and Palm Fronds (during pruning).

Malaysia has approximately 4 million hectares of land under oil palm plantation. Over 75% of total area planted is located in just four states, Sabah, Johor, Pahang and Sarawak, each of which has over half a million hectares under cultivation. The total amount of processed FFB (Fresh Fruit Bunches) was estimated to be 75 million tons while the total amount of EFB produced was estimated to be 16.6 million tons. Around 58 million tons of POME is produced in Malaysia annually, which has the potential to produce an estimated 15 billion m3 of biogas can be produced each year.

Malaysia is the world’s second largest producer of crude palm oil. Almost 70% of the volume from the processing of fresh fruit bunch is removed as wastes in the form of empty fruit bunches, palm kernel shells, palm oil mill effluent etc. With more than 423 mills in Malaysia, this palm oil industry generated around 80 million dry tonnes of biomass in 2010. Malaysia has more than 2400 MW of biomass and 410 MW of biogas potential, out of which only 773MW has been harnessed until 2011.

Rice husk is another important agricultural biomass resource in Malaysia with good potential for power cogeneration. An example of its attractive energy potential is biomass power plant in the state of Perlis which uses rice husk as the main source of fuel and generates 10 MW power to meet the requirements of 30,000 households. The US$15 million project has been undertaken by Bio-Renewable Power Sdn Bhd in collaboration with the Perlis state government, while technology provider is Finland’s Foster Wheeler Energia Oy.

Under the EC-ASEAN Cogeneration Program, there are three ongoing Full Scale Demonstration Projects (FSDPs) – Titi Serong, Sungai Dingin Palm Oil Mill and TSH Bioenergy – to promote biomass energy systems in Malaysia. The 1.5MW Titi Serong power plant, located at Parit Buntar (Perak), is based on rice husk while the 2MW Sungai Dingin Palm Oil Mill project make use of palm kernel shell and fibre to generate steam and electricity. The 14MW TSH Bioenergy Sdn Bhd, located at Tawau (Sabah), is the biggest biomass power plant in Malaysia and utilizes empty fruit bunches, palm oil fibre and palm kernel shell as fuel resources.
