Flexible polyurethane foams are a diverse class of materials encompassing furniture, packaging, automotive, and many other industrial domestic applications. Polyurethane synthesized by the addition polyols isocyanates; however, petroleum origin toxic nature isocyanates have driven to look for more sustainable routes production. Renewable fillers emerged as biobased resource decrease carbon footprint this widely used polymeric material. In study, soy hulls, mass-produced, by-products soybean production, were create biochar beneficial in synthesis flexible foam composites. The hull was found maintain compression properties at decreasing isocyanate index, reducing amount needed addition, decreased flammability foams, important applications where consumer safety is important. results point ability safer, sustainable, even cost-effective through reduction use while maintaining polymers.

Pesticide contamination and soil degradation stand as critical challenges in the agricultural ecosystem. This study delves into impact of nano-biochar (NBC) on properties, alachlor retention, microbial populations, exploring concentrations 1%, 3%, 5% w w-1 both planted unplanted alachlor-contaminated soil. A six-week black bean-pot experiment was conducted The NBC, distinguished by its substantial carbon content remarkable surface area, pore volume, diameter, resulted significant enhancements pH, moisture (MC), organic (SOC). Over 6-week period, NBC3% NBC1% consistently increased SOC content, while NBC5% displayed a declining trend after 4th week. application NBC led to acceleration reduction, achieving efficiencies exceeding 77% soils reaching an impressive 97.3% soils. reduction dynamics, modeled first-order equation, revealed notably shorter half-lives NBC-treated compared controls.

Enhancing soil health, microbial count, and hydrophilic methomyl and hydrophobic lambda-cyhalothrin remediation with biochar and nano-biochar

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 22, 2024

Abstract Pesticide contamination and soil degradation present significant challenges in agricultural ecosystems, driving extensive exploration of biochar (BC) nano-biochar (NBC) as potential solutions. This study examines their effects on properties, microbial communities, the fate two key pesticides: hydrophilic methomyl (MET) hydrophobic lambda-cyhalothrin (LCT), at different concentrations (1%, 3%, 5% w −1 ) soil. Through a carefully designed seven-week black bean pot experiment, results indicated that addition BC/NBC significantly influenced dynamics. Soil pH moisture content (MC) notably increased, accompanied by general rise organic carbon (SOC) content. However, BC5/NBC5 treatments, SOC declined after 2nd or 3rd week. Microbial populations, including total plate count (TPC), phosphate-solubilizing bacteria (PSB), nitrogen-fixing (NFB), showed dynamic responses to applications. BC1/NBC1 BC3/NBC3 applications led increase whereas treatments experienced decline initial surge. Furthermore, removal efficiency both MET LCT increased with higher concentrations, NBC demonstrating greater efficacy than BC. Degradation kinetics, modeled first-order equation, revealed degraded faster LCT. These findings underscore profound impact pesticide dynamics highlighting transform sustainable practices.
