“…HA is a typical kind of HS that can be easily prepared from various biomass wastes via hydrothermal technology ( Shu et al, 2016 ; Wang J. et al, 2017 ; Chang & Huang, 2018 ; Yang et al, 2019 ; Malhotra & Garg, 2020 ; Sriramoju et al, 2020 ; Sui et al, 2021 ). Chang & Huang (2018 ) produced a value-added nutrient solution containing 17% of HA in HT by using sugarcane exocarp as the raw material. This product was used as a liquid organic soil conditioner that can promote crop growth.…”

Humic substances (HSs) occupy 80% of organic matter in soil and have been widely applied for soil remediation agents, potential battery materials, and adsorbents. Since the HS extraction rate is very low by microbial degradation in nature, artificial humification processes such as aerobic composting (AC) and hydrothermal treatment (HT) have attracted a great deal of attention as the most important strategies in HS production. This article aims to provide a state-of-the-art review on the development of conversion of biomass waste into HSs based on AC and HT for the first time in terms of mechanisms, characteristics of HSs’ molecular structure, and influencing factors. In addition, some differences based on the aforementioned information between AC and HT are reviewed and discussed in the conversion of biomass waste into HSs in a pioneering way. For biomass waste conversion, a feasible strategy on effective humification processes by combining AC with HT is proposed.

“…The content of the solid sericite was mainly composed of 23.24% Si and 17.8% Al. The soil had a high Si/Al ratio and a high Si/Fe ratio, indicating that the plants could absorb more Si from the soil [30,31]. Figure 2 shows that the dry sericite powder had a lamellar structure with irregular vertical overlapping; the magnification of photos is about x100.…”

“…The pH and electro-conductivity (EC) of the BNS are 7.0 and 3.5 us/cm, respectively. The ICP element analysis (Table 1) revealed that the sugarcane contained 15.37% K, the rice husk contained 53.28% K, and the peanut shells contained 97.14% K, with high contents of C and Si [29,30]. Figure 3 shows that the addition of BNS and sericite increased rice plant height, number of grains, and panicle weight when compared with Ck (pure water only).…”

“…Therefore, from the viewpoint of circular design for agriculture, we can consider the application of silicon-containing mineral waste such as sericite to promote crop growth. This study used a cellulosic biomass nutrient solution (BNS) made from the hydrothermal carbonization (HC) of agricultural waste, as described in our previous investigations [29,30], and sericite mineral waste to enhance rice growth by reducing empty grains.…”

With the increased importance of a circular economy in the world, in this paper we present a practical “butterfly model” (proposed by the Ellen MacArthur Foundation) case report: to gain extra benefits in rice cropping through hybridizing green products of mineral waste and agricultural waste recycling. Hydrothermal biorefinery was used to turn spent agricultural biomass into a value-added biomass nutrient solution (BNS). BNS and sericite mineral waste were mixed and used as a new hybrid mineral–hydrothermal fertilizer for rice cropping. The most important extra benefit of this new hybrid mineral–hydrothermal fertilizer was that the empty grains could be reduced to 1–4 grains/spike (normally, it is 12–18 grains/spike), without significantly decreasing the panicle weight or spike saturation. This case report provides a new logic for circular design at the “node” point of a butterfly diagram.

“…Technical analysis has also confirmed the potential of agricultural biomass for energy production. Based on observations of field crop growth, Chang and Huang (2018) noted the high sustainable energy potential of hydrothermal carbonization of agricultural biomass waste. The study demonstrated an increase of up to 40% in field crop stem lengths, with fresh crop weights increasing 113%.…”

This paper examines the main determinants of biomass market development from a regional perspective in the context of current EU climate and energy policy. The EU’s targeting of climate neutrality implies a new, multifaceted role for agriculture as a producer of energy resources. The challenge is to orient production to support the sustainable development of the circular economy. The possibility of using agricultural waste as a type of energy raw material aligns with a holistic approach to product management. The use of agricultural biomass as an energy raw material can enable increased energy self-sufficiency and reduced dependence on imported fuels among Poland’s regions and an increase in the country’s energy security. The aim of the study is to identify barriers to and opportunities for the development of the agricultural biomass market. The empirical section presents survey data from interviews with farm owners in the Polish province with the highest agricultural biomass potential, located in a region with one of the largest opencast mines in Europe. The estimated parameters of a logit model indicate that the logistical aspects of raw material collection and organization and a lack of knowledge of biomass are the main barriers to biomass development on the supply side.
