Biochar: Low Carbon Economy As A Soution To Climate Change and the Environment

The high consumption of fossil fuels as the pedestal current economic activity has caused adverse effects on the environment such as the climate change and environmental issues. Accumulation of carbon dioxide concentration in the atmosphere that has exceeded the threshold needs to be reduced to the safe limit. Some things you can do include: improving energy efficiency of various equipment and machines today are still using fossil fuel, using fuel or renewable energy sources and absorb carbon dioxide in the atmosphere. When we review the balance of carbon emitted by the use of renewable fuels or substitution of fossil fuels with renewable energy is carbon neutral, while the absorption of carbon dioxide gas in the atmosphere is carbon negative.

Low-carbon economy as a solution to climate change and the environment is how economic sectors are encouraged to carbon neutral conditions even carbon negative. Biomass energy is one solution to achieve the low-carbon economy. Availability of biomass feedstock in Indonesia in particular, is very abundant and has a small part that is less than 5% is used as an energy source. The Optimum scenario of utilization the biomass into environmentally friendly forms of energy is the next questions when we has dropped the option to use as an energy source.

Continuous pyrolysis technology as a second generation biofuel technology is the best solution in order to establish the era of low-carbon economy. Products such as charcoal / biochar,  biooil, and syngas will be generated by this technology. Especially biomass waste or organic waste can be directly processed at the site to produce the products as above. Agro-industry companies such as palm oil mill generate huge biomass waste every day. Indonesia and Malaysia as the largest palm oil producer in the world or around 87% of world production (2007) that had a lot of palm oil mills is estimated at more than 1,000 units, so that the biomass waste available is overwhelming.

Especially in palm oil industries, product biochar (charcoal) will have a major role to improve soil fertility, including reducing the need for chemical fertilizers (urea) in oil palm plantations, so it will be very profitable. A number of efforts have been carried out by the palm oil companies to increase their effectiveness in fertilization and soil enrichment, and with biochar is like like 1 shoot killed 2 birds, palm solid waste problem can be overcome, gain energy sources and improvement of soil fertility. Biochar (charcoal) in addition to be able to fertilize the soil is capable of capturing carbon dioxide from the atmosphere to a carbon negative mechanism, while biooil and syngas can be applied as a carbon neutral fuel because it comes from biomass.

The Urgency Palm Oil Waste Processing Plant

Production process of palm oil mills generate large amounts of waste every day. Untreated palm oil waste will only cause environmental problems. Orientation of the waste processing in addition to overcome the environment problem should also provide great added value for the oil palm business. Commonly palm oil mill waste is a dilemma between palm oil mill division with the palm oil plantation division, it is because the current practice of waste particularly empty fruit bunches (EFB) will generally be returned to the palm oil plantation to increase the soil fertility by composting. It means that palm oil waste is generated by the palm oil mill division, while the use of compost  is palm oil plantation division. Prior to use in plantation the waste also needs to be processed separately.

 

Judging from the process, biological composting process will take longer time and considerable a huge investment. Pyrolysis is a thermochemical process that is the best process for processing the empty fruit bunch. The main product of biochar can be applied as a medium to improve soil fertility and conserve the use of subsidized urea fertilizer in palm oil plantations, while biooil and syngas for energy applications. Application of pyrolysis system can also revolutionize the energy system in palm oil mill, so become more efficient and environmentally friendly.

Palm oil waste processing company that will become a stand-alone as alternative solution of the problem. Palm oil mill division will not be bothered for waste treatment especially empty fruit bunch while palm oil plantation division can directly get the product ready and apply for palm plantations as their responsibilty. The company is like a bridge between the two divisions and could be set up a separately or joint ventures with palm oil mill and palm oil plantations are best for the benefit of optimization.

Trilema of Energy, Economy and Environment

The big problem facing the world today is energy, economy and environment. All three are interrelated and influence each other. Solving the problem or solution to it can only be done in a comprehensive way, not partial, so that the sustainable development is possible.  That's bad idea when we just focusing on one aspect so the two other aspects are neglected thus enabling larger problem.

By the time the use of renewable energy will continue to increase of its role and will be the primary energy source at a time. This is inline with the public awareness of community for living environmentally and sustainable that continues to grow. Various regulations began to be developed and implemented to accelerate it.

Various scenarios were created for the implementation at application level. Processing biomass waste, organic waste and plastic waste and scrap tires with continuous pyrolysis technology is the best scenario to overcome Trilemma facing today.

Nutrient Management for Palm Oil Plantation

Nutrient management is one of the major cost components for a palm oil plantation. This is due to the inherently poor fertility of most tropical soils and the intensive extractive nature of plantation agriculture. Biochar offers the possibility for a revolution in nutrient use efficiency in tropical agriculture along with many other proven soil and water holding benefits.

Why biochar?

Many advantages of biochar applications to improve the soil fertility. Biochar production process also uses a thermal process that faster and also more affordable in investment than the biological process, that's common called fermentation. Saving estimation of fertilizer use could save up to 50% with the use of biochar, that means increase the fertilization efficiency due to the application of biochar.

 

How to produce biochar?

 

To produce the best biochar in quality and quantity, the best technology is continous slow pyrolysis process. The biomass waste that is generated by palm oil mill every day is a potential raw material for the production of biochar. Syngas, biooil and heat are other products from continous slow pyrolysis technology for energy applications or other.
