How can a biorefinery contribute to a more sustainable future?
Biogas Production
The use of anaerobic digestion technology has made it possible to efficiently convert organic waste into biogas. This renewable energy source can be utilised for generating heat and electricity, which in turn helps reduce greenhouse gas emissions and waste in landfills. Biogas production not only offers a sustainable energy solution, it also assists in tackling waste management issues.
Biochemicals and bioplastics
The development of advanced biorefining methods has made it possible to produce valuable biochemicals and bioplastics from renewable resources. Bioplastics currently make up 0.6 percent of overall plastic production, which amounts to some 380 million tonnes per year. These eco-friendly alternatives to fossil fuel-based chemicals and plastics help reduce carbon emissions and preserve limited fossil fuel reserves.
Waste Valorisation
Waste valorisation advancements have paved the way for transforming types of waste streams into valuable products. By extracting and utilising the resources found in waste materials we can reduce landfill waste and reclaim valuable materials. This approach not only reduces environmental impact but also creates economic opportunities and promotes a sustainable and circular economy.
The environmental impact of biorefineries
Reducing greenhouse gas emissions
Transitioning to renewable energy sources like solar, wind and biomass allow biorefineries to reduce their carbon footprint by lowering their greenhouse gas emission levels. Biorefineries can also play a significant part in capturing and storing carbon dioxide emissions using technologies such as carbon capture and storage (CCS) or carbon capture and utilisation. Achieving carbon neutrality has been calculated to require a 55% to 75% reduction in emission rates, coupled with sustainable development initiatives that offset or sequester the remaining 25% to 45%. Bioenergy could present a solution to achieve these goals.
Water conservation and management
Biorefineries have the option to incorporate water recycling systems in order to minimise the amount of water used and alleviate pressure on water resources. These systems are designed to capture and purify water used in processes like cooling, cleaning and production. The purified water can then be reused for drinking purposes such as irrigation or equipment cleaning reducing the demand, for fresh water. Biorefineries naturally produce wastewater as a byproduct of their operations. To reduce the environmental impact, biorefineries treat this wastewater to eliminate pollutants and ensure it meets the necessary environmental standards before being released.
Waste management and recycling
Biorefineries have gained recognition for their capability to transform waste materials into valuable products. Using methods like fermentation, anaerobic digestion and pyrolysis biorefineries can convert waste into biofuels, biochemicals and other sustainable materials. These refineries consistently work towards mitigating waste generation by optimising their processes. By enhancing efficiency and adopting practices the goal is to minimise the amount of waste generated during the conversion of raw materials, into valuable products.
