# Technology-Economy-Policy: Biochar in the Low-Carbon Energy Transition--A Review
## 8 Conclusions and Future Prospects  
In the body of this paper, the authors focused on a broad discussion of biomass-to-biochar transformation as a strategy with multiple environmental benefits, which appears to be key to combating accelerating climate change by reducing pollution and maintaining environmental sustainability. In this paper, the authors highlighted the promising role of biochar in the energy industry, which can help achieve sustainability goals for carbon neutrality and build a circular economy. The subject's scientific literature reports that waste biomass material with a negative carbon footprint, which is biochar, is showing applications both in and out of soil in the fight against climate change to achieve carbon neutrality. Biochar as a soil additive can positively increase water retention and nutrient use efficiency, accelerate plant growth, increase waste recycling and microbial diversity, inhibit pathogen activity, reduce fertilizer requirements and irrigation frequency, and minimize greenhouse gas emissions. Biochar can bind CO\({}_{2}\) in the long term and prevent the release of carbon back into the atmosphere, thus promoting net zero emissions under the UN Sustainable Development Goals. Biochar can significantly sequester carbon dioxide in the soil. In addition, biochar can be used as a green catalyst in biorefinery, remove organic and inorganic pollutants in the construction industry, and aid in carbon capture and energy storage, etc. Achieving net zero carbon emissions is a difficult but necessary task. Using waste to produce biochar appears to be a good investment to promote a circular economy. However, more research and analysis are still needed to assess the economic and environmental benefits of a circular economy. More field and local studiesare needed to assess the environmental impact of biochar before large-scale use. It is essential to continuously make the public, especially farmers and entrepreneurs, aware of the topics of carbon dioxide sequestration, sustainability, and carbon dioxide pricing so that they understand and appreciate the potential of biochar in solving the global problems of the energy industry, agriculture, and climate change. Achieving carbon neutrality is an arduous task that requires long-term strategies. The various uses of biochar do not reflect it as a solution to all climate change problems. However, the development of value-added products through the valorization of biochar has commercial applications in various sectors, which minimizes the environmental burden and enhances environmental protection, bringing local economic and global environmental benefits. The European market for biochar is largely driven by the increasing use of sustainable agricultural practices. Farmers and agricultural stakeholders are increasingly recognizing the benefits of biochar in improving soil health, increasing yields, and reducing the need for chemical fertilizers. Biomass is expected to be a major energy source in the coming decades. Biomass has the potential to become the best alternative to fossil fuels due to its easy availability, renewability, carbon neutrality, and relatively low sulfur content. Using biomass as an energy source instead of fossil fuels can reduce pollution and global warming, alleviate energy shortages, and promote sustainable development. In addition to improving production efficiency, future research should focus on expanding biochar's applications across multiple sectors. Its multifunctional role makes it a crucial component in circular economies, especially in regions with limited resources or high pollution. Biochar's ability to mitigate environmental contamination positions it as a key solution for waste management and land reclamation. Additionally, its use in carbon-negative construction materials could play an important role in the building industry. To maximize biochar's potential, it is essential to establish policies that incentivize its development. Conceptualization, A.S. and B.S. ; methodology, B.S. and A.S.; formal analysis, B.S.
