United Nations charter to build a sustainable future has paved the way for the introduction of the Sustainability Development Goals (SDGs) at a global forum. In particular, SDG 11 is aligned with the idea of developing cities and communities that provide quality human life, by attaining net-zero discharge and self-sustainability. In line with the efforts of the global community, biochar has emerged as a viable solution due to its ability to convert waste into value. Finding applications in a spectrum of domains, biochar is being studied for use as an adsorbent, a co-catalyst to promote industrial-grade reactions and as a feed for fuel cells. Moreover, the inclusion of biochar as a soil enhancement material advocates the implementation of closed-loop nutrient cycles. Hence, it is imperative to have a proper understanding of the biomass characteristics, the hydrothermal treatment and the process parameters to be adopted for the production of char in order to identify biomass feedstock based on the application. The current work provides insight into the key factors and conditions employed for the production of biochar based on the plethora of applications. In order build a basic framework to aid in the production of char, the development of a statistical correlation was undertaken to determine the feed and optimum process parameters for the production of biochar based on its applications.
《联合国宪章》为建设可持续未来铺平了道路，使得可持续发展目标（SDGs）得以在全球论坛上推出。特别是，可持续发展目标11与发展能够提供优质人类生活的城市和社区的理念相一致，通过实现净零排放和自我可持续性来达成这一目标。与国际社会的努力相一致，生物炭因其能够将废物转化为价值而成为一种可行的解决方案。生物炭在一系列领域都有应用，正被研究用作吸附剂、促进工业级反应的助催化剂以及燃料电池的燃料。此外，将生物炭作为土壤改良材料体现了闭环养分循环的实施。因此，为了根据应用确定生物质原料，必须正确了解生物质特性、水热处理以及生产炭所采用的工艺参数。当前的工作基于大量应用，深入探讨了生产生物炭所采用的关键因素和条件。为了构建一个有助于炭生产的基本框架，进行了统计相关性分析，以根据生物炭的应用确定其生产的原料和最佳工艺参数。
