Composting behavior in Japan: an application of the theory of consumption values

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 8

Published: Jan. 10, 2025

Ensuring effective and sustainable management of organic waste is a global challenge, especially in countries with limited land, such as Japan, where reducing, reusing, recycling food particularly crucial. The present research used the theory consumption values (TCV) to investigate main factors that encourage Japanese households engage composting. hypotheses were evaluated using ordinal partial least squares structural equation modeling (OrdPLS). model results suggest household composting Japan influenced by social approval (social value), visibility behavior existing knowledge about (epistemic convenience (functional interest gardening or farming, an individual’s availability participate (conditional value). Factors emotions (emotional gender, type housing, size did not significantly impact practice Both positive negative functional aspects found affect perceptions convenience, thereby indirectly influencing decision compost. findings promoting ongoing training support, improving linking urban community gardens, public spaces could enhance participation, even among those who do garden.

Advances in Hydrothermal Carbonization for Biomass Wastewater Valorization: Optimizing Nitrogen and Phosphorus Nutrient Management to Enhance Agricultural and Ecological Outcomes

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 800 - 800

Published: March 11, 2025

This study presents a novel approach that integrates hydrothermal carbonization (HTC) technology with circular economy principles to optimize the management of nitrogen and phosphorus in agricultural wastewater. Given increasing global resource scarcity continuous ecological degradation, valorization biomass wastewater has become critical pathway for promotion sustainable development. Biomass wastewater, which contains crop residues, forestry leftovers, food processing byproducts, long been regarded as useless waste. However, this abundant organic matter possesses significant renewable energy potential. The can significantly reduce environmental pollution. Through optimization HTC process parameters, we achieved an improvement quality yield carbonized products, facilitating efficient recycling utilization resources. research demonstrates transform into valuable biofertilizers, energy, feed, while simultaneously reducing reliance on fossil fuels, decreasing greenhouse gas emissions, mitigating impact activities. paper provides comprehensive exploration application ecosystems, highlighting its beneficial role management, efficiency, pollution reduction. findings suggest holds potential optimizing treatment, promoting recycling, advancing Furthermore, offers theoretical support practical guidance implementation is paramount importance fostering economic development achieving agriculture.

Regeneration of Pinus patula-derived biochar employed in crystal violet removal in water

Universitas Scientiarum, Journal Year: 2025, Volume and Issue: unknown, P. 22 - 38

Published: March 17, 2025

Biochar (BC) is a promising adsorbing material used to eliminate different contaminants from water, including dyes. However, the applicability and cost-effectiveness of this adsorbent also depend on its regeneration capacity. Several approaches BC are known, each yielding variable efficiencies, risks generating secondary pollution, difficulties application, contrasting cost/benefit ratios. Chemical one techniques best results in contaminant desorption surface. The present study evaluated Pinus patula pellet-derived employed Crystal Violet (CV) adsorption water using several acids, bases, solvents. tested agents included solutions hydrochloric acid (HCl) 0.1 M, acetic (CH3COOH) 1 75 % ethanol (C2H6O), two 95:5 mixtures (75 96 %) concentrated acid. mixture ethanol-concentrated was best-performing solvent with efficiency 21.1 %. Therefore, it chosen as agent for six consecutive adsorption-desorption cycles. After these cycles, removal decreased up 54.4 This work revealed that has good capacity, which could reduce costs implementing decontamination process having positive impact sustainable development by aligning circular bioeconomy principles.

Hydrochars derived from real organic wastes as carbonaceous precursors of activated carbons for the removal of NO from contaminated gas streams

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 945, P. 173897 - 173897

Published: June 18, 2024

The improvement of air quality in densely-populated urban regions constitutes an environmental challenge increasing concern. In this respect, the abatement NO emissions, primarily emanating from combustion processes associated with motor-vehicles, along industrial/domestic systems, represents one main problems. Here, three hydrochars diverse organic residues were used as activated carbon precursors for their evaluation removal two potential application scenarios. Hydrochars physically at 800 °C pure-CO2 or diluted-O2. These materials tested a lab-scale biofilter different conditions (NO concentration, temperature, relative humidity, NO-containing gas and particle size) larger-scale to evaluate long-term capacity. Hydrochar-derived carbons present relatively well-developed micro- mesoporous structure, BET areas up 421 m2/g, variety oxygen surface functionalities (carboxylic, lactone, carbonyl quinone groups), especially concerning CO2-activated carbons. exhibited excellent behaviour low concentration (5 ppmv) between 25 75 capacities ≈97 % > 82 %, respectively; still good-performance (≈66 %) more concentrated (120 ppmv). Whilst, obtained by diluted-O2 activation same hydrochars, evidenced higher capacity loss high concentration. O2 presence stream was confirmed crucial factor elimination, since both co-adsorb on favouring oxidation NO2. Besides, humidity airstream diminished 0.88 0.51 mgNO/gcarbon, but remained 0.54 when (in pellet) operated 9-fold longer test under humid air. Therefore, study highlights renewable serve cost-effective component biofilters, mitigate emissions exhaust gases biomass boilers semi-close areas.
