by Sustainable Bioenergy Resources
Bioenergy comes from various bio-resources including biomass, biogas and biofuels. Biomass is organic non-fossil material of biological origin that includes plant and animal matter such as agricultural crops and residues, forest residues, organic municipal and industrial wastes. These biomass resources can be combusted directly for heat and power generation or converted to solid, liquid and gaseous biofuels through various thermochemical and biochemical processes. Biogas is a combustible gas produced by the bacterial breakdown of organic matter in an oxygen-free environment. It is produced from biomass sources through anaerobic digestion and can be used for heat and power generation. Biofuels include ethanol from corn and sugarcane and biodiesel from vegetable oils, animal fats and other feedstocks that can be used in vehicles as alternatives to fossil fuels.
Bioenergy Advantages
Bioenergy from Sustainable Bioenergy produced renewable resources has several environmental advantages compared to fossil fuels. It is carbon-neutral as the carbon dioxide released during combustion was recently absorbed from the atmosphere by growing biomass plants through photosynthesis. This is in contrast to fossil fuels that release carbon stored in the earth over millions of years. When bioenergy feedstocks are grown and harvested sustainably on degraded and marginal lands, it does not put pressure on food production or natural ecosystems. The widespread use of bioenergy can contribute significantly to energy security by diversifying energy sources and reducing dependence on imported fossil fuels. Biomass and biogas based decentralised energy generation options provide opportunities for rural development and employment generation. Advanced biofuels like cellulosic ethanol have the potential for net lifecycle greenhouse gas reductions compared to gasoline.
Sustainable Biomass Production
For bioenergy to be truly sustainable, biomass feedstocks need to be produced sustainably without negatively impacting the environment, biodiversity or competing with food production. Some principles of sustainable biomass production include use of degraded and marginal lands not suitable for food crops, following best agricultural and forestry practices to protect soil and water resources, maintaining or enhancing biodiversity in production areas and ensuring security of land tenure and equitable benefit sharing for farmers and local communities. Perennial lignocellulosic crops like Miscanthus and short rotation coppice can boost soil carbon sequestration compared to annual food crops when grown on marginal lands. Forest residues and byproducts from sustainable forest management including timber harvesting can be used for bioenergy without compromising forest conservation goals. Waste biomass from food processing, urban green waste also present opportunities for sustainable bioenergy feedstock supply without direct land use impacts.
Biogas from Waste and Residues
Biogas is a particularly promising route for sustainable bioenergy production since it relies on waste organic streams that do not require additional land or inputs. Animal manures and agricultural residues like straw and husks that would otherwise be burned or left to decompose, emitting greenhouse gases can be converted to biogas through anaerobic digestion. This process not only produces a renewable energy source in forms of methane rich biogas that can substitute for fossil natural gas but also generates digestate as an organic fertilizer reducing dependence on chemical fertilizers. Municipal organic wastes from food, green waste and sewage sludge are also suitable feedstocks for biogas plants located near urban areas. Capturing biogas from these waste streams presents an opportunity to produce renewable energy while achieving waste management goals through diversion from landfills where methane, a potent greenhouse gas would otherwise be emitted.
Advanced Biofuels Technologies
While first generation biofuels like corn ethanol and biodiesel faced sustainability issues, advanced technologies offer promising pathways for sustainable “drop-in” biofuels that can directly substitute for fossil fuels in vehicles and jets. Cellulosic or second generation bioethanol produced through enzymatic breakdown of lignocellulosic biomass like agricultural residues, energy crops and forestry wastes does not impact food production. Technologies are being developed and demo plants commissioned to produce cellulosic ethanol commercially. Hydroprocessed esters and fatty acids or HEEFA biodiesel produced through hydroprocessing of waste oils and fats has the potential for large scale commercial production. Algal biofuels and biorefineries producing a range of biofuels and bioproducts offer routes for producing transport fuels sustainably without agricultural land-use. Continued support for research, development and demonstration of advanced biofuels technologies is needed for commercialization and uptake at scale to meaningfully reduce emissions from transportation sector.
sustainably produced bioenergy from wastes, residues and purpose-grown energy crops not impacting food production or ecosystems presents opportunities for large scale deployment of renewable alternative to fossil fuels for heat, power and transportation needs. Ensuring sustainable feedstock production and use of latest conversion technologies is important for realizing socio-economic and environmental benefits of the bioeconomy. Ongoing R&D on advanced technologies will help make cellulosic biofuels and renewable chemicals commercially viable and reduce greenhouse gas emissions through substitution of petroleum based products and fossil fuel usage over the long term.
