“…The obtained PW was analyzed and indicates that TOC, COD, and BOD values are much higher than those of common domestic wastewater [41]. Quicker and Weber, 2016, give ranges of values for COD from 4900 to 78,000 mg L −1 , for BOD 5 1700-42,000 mg L −1, and TOC 4000-31,700 mg L −1 [34]. TOC includes mainly organic acids, sugars, and fatty acids [44].…”

“…The technology was temporarily tested on a sewage treatment plant in Düsseldorf (Germany) but was discontinued after a test phase [33]. Currently, there are various approaches to the industrial implementation of the technology as a process, optionally as a multi-batch process (quasi-continuous) or as a process in tubular reactors [26,34]. There are some providers of commercial HTC solutions, like TerraNova Energy, HTCycle, or SunCoal Industries [3].…”

Hydrothermal carbonization (HTC) has developed considerably over the last 15 years and offers a viable alternative for the utilization of municipal and industrial organic waste such as sewage sludge. However, the technology has yet to establish itself as a valorization process for waste biomasses (2024) and is not yet a recognized state of the art. Nevertheless, the HTC technology could gain greater relevance in the future, especially as an alternative valorization pathway for sewage sludge. During HTC, significant amounts of HTC process water (PW) are produced as a byproduct. The process water is inorganically and organically polluted and has to be treated, as it would be a burden on water bodies and thus on the environment if left untreated. In the EU and specifically Germany, industrial wastewater producers like HTC-plant operators are obliged to treat their industrial wastewater before discharging it into the environment. In addition to a large amount of PW and its treatment to the required limits, the organic load and possible persistent and toxic substances pose major challenges for plant operators. Many proven processes from industrial wastewater treatment were transferred for the treatment of PW. Treatment of the PW in a manner that is industrially viable, economically viable, and efficient is crucial for the effective commercialization of HTC technology. In this, the challenges and opportunities of PW composition, management, and treatment, including legal aspects, are mainly discussed. Therefore, the legal framework in the European Union and specifically for Germany will be elaborated. Furthermore, different treatment pathways are also highlighted.

“…12 Porosity, a key property for biochar applications that involve interaction with a fluid stream, is correlated to the specific surface area usually measured by BET analysis. 13 Great development of the specific surface area can be achieved in the case of the biochar produced under steam-assisted pyrolysis conditions. For example, biochar with BET equal to 380 m 2 g À1 is produced from steam-assisted slow pyrolysis of eucalyptus at 700 1C.…”

“…Biochar, a solid substance made from the pyrolysis of organic matter, has been used in agriculture for a long time as a soil conditioner for the improvement of soil fertility, carbon sequestration, and plantfriendly root zone environment. It will boost plant survival and growth when paired with nutrient enrichment [8,14,15]. Application of biochar along with nutrient enrichment might be advantageous for soil organic carbon (SOC) sequestration and crop production on degraded and severely weathered soils, such as Spodosols in the tropics.…”

Tropical Spodosols are highly fragile and disturbed Spodosols remain unproductive at conventional management practices due to the inherent infertility of the soils. These soils developed from quartz rocks and are characterized by the presence of E albic and B spodic horizons. This study was conducted to determine the effect of enriched biochar application on height growth of jabon (Anthocephalus cadamba) stands planted on spodosols. Research plots were arranged to comply with a 2-factors completely randomized design (CRD) procedure – 3 levels of rate of biochar treatment (A1 = 0%v, A2 = 2%v and A3 = 5%v) and 2 levels of liquid organic fertilizer enrichment (B0 = without enrichment and B1 = with enrichment). There were 3 replicates for each treatment consisted of 28 Jabon (Anthocephalus cadamba) plants at 2.5 m x 3 m spacing, therefore a total of 504 plants were observed in this study. Results showed that the rate of biochar and nutrient enrichment gave a significant effect on the height growth of jabon plants (A. cadamba), the best height growth was obtained at the enriched biochar treatment rate of 5%v (A3B1).
