This work studies the valorization of swine manure by hydrothermal carbonization in batch and continuous mode (T 180 – 250 ºC, residence time 45 min, 5 wt.% total solids). The process resulted a hydrochar with enhanced degree, higher C content (50 55 wt.%) fixed carbon (FC: ~ 25 increased calorific value (20 - 22 MJ kg-1), compared to obtained process. In particular, mass yield was significantly lower at low temperature 43 wt.%), being very similar both processes highest temperatures (~ 20 wt.%). Thermogravimetric combustion analysis showed that hydrochars exhibited suitable characteristics as solid biofuels for industrial use. water cases high organic matter soluble chemical oxygen demand (7 g L-1) (4 10 L-1), although gave rise diversity aromatic N- O-containing species. longer required reach operating case system (heating ramp) reduced H/C (1.07 1.35) O/C (0.47 0.64) ratios (H/C 1.32 1.54 0.54 0.65), which implied more important role feedstock dehydration decarboxylation reactions.

This work studies the fate of nutrients (N, P, and K) during hydrothermal treatment anaerobically digested sewage sludge to raise their concentrations in liquid phase facilitate recovery as solid minerals by chemical precipitation. The process has been optimized evaluating temperature (170–230 °C) reaction time (5–60 min) an acid-free medium or with addition HCl (0.1–0.5 M). In reactions, were mainly concentrated hydrochar, which extracted 0.5 M (10% w/v). Following this route, 6.9 g N/kg, 13.8 P/kg, 8.8 K/kg contained feedstock from hydrochar produced at 230 °C, which, considering direct nutrient solubilization water treatments, accounts for 82, 83, 78% N, K release, respectively. HCl-assisted treatment, release directly into was improved depended on acid concentration used a lesser extent temperature. Operating °C HCl, 98% N (more than 45% NH4–N), 87% P (as PO4–P), 70% achieved water. Chemical precipitation phosphorus nitrogen allowed identified crystalline struvite, high contents Mg, NH4–N negligible heavy-metal content. estimated cost could reach 13.7 euros per tonne, energy inputs required treatment.

Urban agriculture (UA) activities are increasing in popularity and importance due to greater food demands reductions agricultural land, also advocating for local supply security as well the social community cohesion perspective. This activity has potential enhance circularity of urban flows, repurposing nutrients from waste sources, their self-sufficiency, reducing nutrient loss into environment, avoiding environmental cost extraction synthetization. The present work is aimed at defining recovery technologies outlined literature obtain relevant such N P sources areas.

Hydrothermal carbonization (HTC) is considered a promising technology for biomass waste management without pre-drying. This study explores the potential swine manure by comparing batch and continuous processes, emphasizing benefits of mode, particularly its full-scale application. The process at low temperature (180 °C) resulted in hydrochar with lower degree compared to process, but similar characteristics were found both hydrochars higher operating temperatures (230-250 °C), such as C content (∼ 52 wt%), fixed carbon 24 wt%) calorific value (21 MJ kg

The two-stage conversion of blackcurrant pomace as an industrial wet-type waste is presented. Firstly, the was hydrothermally processed in a single solvent (water) and binary system (water mixed with isopropanol) at low moderate processing temperatures (225 275 °C, respectively). More specifically, focus put on investigating effect operating conditions change yield distribution bioproducts, particularly solid hydrochar. Also, composition, textural properties, morphology hydrochars were examined by DRIFT, SEM, XRF, low-temperature nitrogen adsorption. In subsequent step, upgrading resultant via fast pyrolysis using microscale techniques (pyrolysis coupled gas chromatography mass spectrometry) thermogravimetric analysis done. studies proved that proposed approach allows to obtain alternative products exhibiting high energy density (21.9–29.3 MJ/kg) could be useful for power heat generation. It found involves noticeably deeper decomposition pristine biomass structure. Furthermore, through processing, it possible value-added chemicals, such hydrocarbons, potential serve advanced biocomponents or reagents chemical industry.

Abstract Handling the global food waste requires sustainable solutions. Anaerobic digestion (AD) is a common approach for remediation and bioenergy production which has been traditionally used mainly methane production. Shifting focus from to volatile fatty acids (VFAs), such as acetic, propionic, butyric acids, offers promising alternatives due their diverse applications higher added value. Achieving desired AD product distributions comprehensive understanding of factors like temperature, pH, feedstock composition, complex microbial dynamics inherent in AD. Various modeling approaches exist, simple equations flux balance analysis (FBA) machine learning (ML) model. The Digestion Model No. 1 (ADM 1) commonly kinetic model, striking reasonable between parameter requirements biochemical details involved Yet, it falls short capturing specific VFAs caproic acid integrating information directly. We present ADToolbox, Python package metabolism. ADToolbox incorporates metagenomic into an enhanced ADM model accommodates more detailed degradation VFA methanogenesis provides variety interfaces command line interface interactive web interface, API, facilitating large-scale analyses simulations. In this article we indicate that prioritizing aspect enhances flexibility predictive power terms accuracy, contributing management strategies.
