Abstract Introduction In addition to produce biogas, the anaerobic digestion process releases a significant quantity of solid digestate (DG), C‐rich byproduct suitable both as soil improver and biosorbent organic inorganic pollutants. This study considered mixed biowaste DG two aerobic DG‐derivatives such compost (CP) vermicompost (VC). Materials Methods A multianalytical approach was adopted comprehensively characterize DG, CP VC. Elemental composition determined by total reflection X‐ray fluorescence (TXRF) spectroscopy; micromorphological features, surface elements area were evaluated scanning electron microscopy coupled with energy dispersive (SEM‐EDX) technique Brunauer–Emmett–Teller (BET) analysis; functional properties investigated attenuated reflectance‐Fourier transform infrared (FTIR‐ATR) spectroscopy Raman spectroscopy. Results TXRF analysis showed that had highest K content (~8.9 g kg −1 ), while VC maximum P, S Ca contents, appreciable levels essential plant micronutrients, Mn, Fe, Cu Zn. SEM‐EDX evidenced heterogeneous surfaces low porosity all materials. BET relevant specific areas and, especially, (~1.6 m 2 ). FTIR‐ATR allowed identify various aliphatic aromatic groups materials provided information on their major molecular classes, lignocellulosic moieties components. The latter techniques also contributed understand chemical transformations after treatments. Conclusion overall results obtained confirmed valuable potential these in improving physical fertility retaining pollutants, consequent benefits for mantaining productivity preserving ecosystem health.

Abstract The incorporation of organic amendments, such as food waste (FW) and biochar, into soil is an established agronomic practice known for enhancing fertility improving overall health. However, the individual combined effects FW biochar on properties in microplastic (MP)-contaminated soil–plant systems remain poorly understood. To address this knowledge gap, we conducted a field experiment to investigate polystyrene MPs, FW, FW-derived lettuce growth. Soil chemical were unaffected by addition MPs. application increased pH, with highest pH (8.2) observed treatment Despite presence resulted notable increases electrical conductivity (EC; 2.04 dS m −1 ), available nitrogen (NO 3 − –N: 325.5 mg kg , NH 4 + 105.2 phosphorus (88.4 total exchangeable cations (18.6 cmol (+) ). these values decreased after cultivation.

Abstract The circular economy (CE) has gained global attention for its potential to promote sustainable production and consumption through continuous growth the efficient use of resources. Despite several reports highlighting benefits, there is still a lack concrete proven studies examining importance institutional pressures transition towards CE in food supply chains. This study aims address this gap by conducting Systematic Literature Review (SLR) identify drivers barriers institutionalisation chains, propose practical managerial implications achieving pressure. We reviewed 25 conducted descriptive analysis papers per year journal, followed categorical thematic analysis. results indicate that normative were most frequently identified among different pressures, mimetic coercive pressures.

Continuous cropping has emerged as a significant challenge affecting yield and quality in greenhouse strawberries, particularly the cultivation of strawberries protected crop continues to increase. To address this issue, substrates with 0 or 2 years continuous were fertilized two types organic materials: vermicompost derived from either sludge cattle manure. A control group consisted substrate without addition vermicompost. Both type improved fertility, promoted plant growth fruit quality. The manure had better improvement effect at peak fruiting stage. Substrate nutrients increased 14.58~38.52% (0-year substrate) 12.04%~42.54% (2-year substrate), respectively. In both types, there was substantial increase microbial population enzyme activity, accompanied by decrease phenolic acid content. During senescence stage, use led enhancements height, leaf area, root length, increases ranging 15.01% 32.77% 23.75% 32.78% across compared group. Furthermore, application significantly Compared (CK), 18.29% 19.64% 0- 2-year substrates, contents soluble sugars, vitamin C, free amino acids fruits 21.42%~34.16% 9.62%~42.62% Cattle ranked higher membership function than CK treatment 0-year planting. conclusion, can improve strawberry quality, well characteristics, thus effectively addressing challenges associated cropping. produced more pronounced positive effects.
