Sustainable Application for Agriculture Using Biochar-Based Slow-Release Fertilizers: A Review

ACS Sustainable Chemistry & Engineering, Journal Year: 2022, Volume and Issue: 11(1), P. 1 - 12

Published: Dec. 29, 2022

The continuous increase in the world population, combined with rapid degradation of arable land, has put a strain on agricultural production. excessive use conventional fertilizers leads to environmental issues associated loss nutrients through leaching, volatilization, denitrification, and surface runoff. Biochar-based slow-release (BSRFs) derived from biomass waste could effectively alleviate by improving soil properties, slowing nutrient release, enhancing plant uptake efficiency. goal this review is outline current progress application BSRFs. properties construction BSRFs were described. raw materials source, preparation conditions, mechanisms introduced detail. Nutrient composition physicochemical be selectively given, which provides basis for practical application. Based evaluation technical, economic, environmental, political factors BSRFs, it proposed apply agriculture other fields such as urban parks gardens.

Phosphorus recovery using magnesium-enriched biochar and its potential use as fertilizer

Archives of Agronomy and Soil Science, Journal Year: 2020, Volume and Issue: 67(8), P. 1017 - 1033

Published: May 18, 2020

Phosphorus (P) recovery from wastewater using biochar is an alternative to P recycle and reuse. However, the impregnation of cations for production needed enhance removal. We aimed at studying adsorption release capacity enriched with masgnesium (Mg2+) its potential use as fertilizer. Biochars were produced poultry litter (PLB), pig manure (PMB), sewage sludge (SSB) impregnated MgCl2. Characterization comprised pH, Electrical conductivity, total nutrient content, moisture ash contents, FTIR, XRD, Raman, SEM-EDX. isotherms by biochars obtained desorption was also studied. A pot experiment maize in Oxisol performed P-loaded biochars, triple superphosphate – TSP (positive control) no application (negative control). PMB showed highest (68.0 mg g−1). The main mechanisms removal through precipitation cations, ligand exchange reactions electrostatic attraction on surface. promoted plant growth accumulation maize, which similar or greater than TSP. In conclusion, Mg-impregnated a sustainable option add value organic residues be reused enhanced efficiency

Retrofitting Municipal Wastewater Treatment Facilities toward a Greener and Circular Economy by Virtue of Resource Recovery: Techno-Economic Analysis and Life Cycle Assessment

ACS Sustainable Chemistry & Engineering, Journal Year: 2020, Volume and Issue: 8(36), P. 13823 - 13837

Published: Aug. 19, 2020

A promising route to transition wastewater treatment facilities (WWTFs) from energy-consuming net energy-positive is retrofit existing with process modifications, residual biosolid upcycling, and effluent thermal energy recovery. This study assesses the economics life cycle environmental impacts of three proposed retrofits WWTFs that consider thermochemical conversion technologies, namely, hydrothermal liquefaction, slow pyrolysis, fast along advanced bioreactors. The results are in turn compared reference design, showing retrofitting design an up-flow anaerobic sludge blanket has highest present value (NPV) $177.36MM over a 20-year plant lifetime despite 15% higher annual production costs than design. According ReCiPe method, chlorination identified as major contributor for most impact categories all cases. There several uncertainties embedded techno-economic analysis assessment, including discount rate, capital investment, sewer prices main products; among which, price biochar presents widest variation $50 $1900/t. Sensitivity analyses reveal rates causes significant changes NPVs. more pronounced pyrolysis-based pathway pyrolysis since product pyrolysis.
