Desenvolvimento De Biocompósito Para Cobertura De Solo Em Sistemas De Cultivo Agrícola
Summary
Researchers developed biodegradable cassava starch films incorporating glycerol, malic acid, and carbon black for use as agricultural soil mulch, evaluating wettability, water absorption, moisture content, and compostability, and finding that additives reduced hydrofilicity and improved physical integrity during biodegradation tests.
Resumo: O trabalho teve como objetivo desenvolver filmes biodegradveis para cobertura de solo (mulching) base de amido de mandioca, plastificado com glicerol e aditivado com cido mlico e negro de fumo.As formulaes foram obtidas pelo mtodo de casting e avaliadas quanto s propriedades de molhabilidade, absoro de gua e umidade, alm da biodegradabilidade em ambiente de compostagem.Os resultados demonstraram que a adio de negro de fumo e cido mlico melhorou a resistncia dos filmes absoro de gua, reduzindo sua hidrofilicidade e aumentando a integridade fsica.No ensaio de biodegradao,

Sprayable starch films for agricultural mulching
This study developed biodegradable cassava starch films sprayed directly onto agricultural soil as a plastic-free alternative to conventional plastic mulch films. Replacing plastic agricultural mulches with biodegradable alternatives could significantly reduce the microplastic contamination accumulating in farmland soil.
Does the Incorporation of Biochar in Biodegradable Mulch Films Affect Soil Carbon Stock?
This review examines whether adding biochar to biodegradable agricultural mulch films can improve their environmental profile by increasing soil carbon, but concludes the evidence is insufficient — the combination could alter greenhouse gas emissions and microbial diversity in unpredictable ways. The paper also notes that biodegradable mulch films still generate microplastic residues in soil, meaning more research is needed before they can be treated as a clean replacement for conventional plastic films.
Does the Incorporation of Biochar into Biodegradable Mulch Films Provide Agricultural Soil Benefits?
Researchers tested whether incorporating biochar into biodegradable plastic mulch films provides agricultural or environmental benefits compared to standard biodegradable mulch. Biochar addition improved some soil properties and degradation behavior but results were mixed across different crop and soil conditions.
Recent Developments in Cassava (Manihot esculenta) Based Biocomposites and Their Potential Industrial Applications: A Comprehensive Review
This review covered recent advances in cassava-based biocomposites and biopolymers as sustainable alternatives to petroleum-based plastics, surveying applications in packaging, agriculture, and construction. Cassava starch and its derivatives showed versatile performance when blended with other natural polymers or reinforced with natural fibers.
Revalorization of Yerba Mate Residues: Biopolymers-Based Films of Dual Wettability as Potential Mulching Materials
This is not about microplastics — it is a materials science study developing biodegradable mulching films from Yerba Mate agricultural residues, cellulose nanofibers, chitosan, and polylactic acid, aimed at replacing conventional plastic mulch films with a compostable alternative.
