Grapevine Biochar/biodegradable Polymer Composites and its Application in Slow-Release Fertilizer

Abstract:

Our previous research has demonstrated that biochar derived from agricultural waste grapevines (GVBC) can enhance the degradation of polylactic acid (PLA). This effect can be harnessed to control the viscosity and degradation rate of composite materials, aiding in the production of slow-release fertilizers and reducing the persistence of polymers in the soil. Specifically, in the context of slow-release fertilizers, incorporating more than 5 phr of GVBC into the composite material provides a slow-release effect. The release rate of the fertilizer can be adjusted based on the GVBC content to match the different growth stages of plants. The biochar used in this study not only aids in carbon sequestration and improves soil conditions but also accelerates the degradation of PLA, thereby increasing the value of agricultural waste. Utilizing slow-release fertilizers enhances their economic value and makes them more environmentally and plant-friendly.
