Human activity is accompanied by the introduction of excessive amounts of artificial materials, including geosynthetics, into the environment, causing global environmental pollution. Moreover, climate change continues to negatively affect global water resources. With the intensification of environmental problems, material reusability and water consumption limitations have been proposed. This study replaced synthetic soil additives with biodegradable materials and analysed the potential and sustainable processing of natural fibrous materials, which form problematic waste. Waste fibres are the basis of innovative soil water storage technologies in the form of biodegradable and water-absorbing geocomposites (BioWAG). We analysed the influence of BioWAGs on plant vegetation and the environment through a three-year field experiment. Furthermore, biomass increases, drought effect reductions, and biodegradation mechanisms were analysed. Natural waste fibres had a positive influence, as they released easily accessible nutrients into the soil during biodegradation. BioWAGs had a positive influence on the biometric parameters of grass, increasing biomass growth by 430 %. Our results indicated that this is an effective method of waste fibre management that offers the possibility to manufacture innovative, environmentally friendly materials in compliance with the objectives of circular economy and the expectations of users.
人类活动伴随着大量人工材料（包括土工合成材料）进入环境，造成全球环境污染。此外，气候变化继续对全球水资源产生负面影响。随着环境问题的加剧，提出了材料的再利用和用水量限制。本研究用可生物降解材料替代合成土壤添加剂，并分析了天然纤维材料的潜在可持续加工，这些材料形成了有问题的废物。废弃纤维是可生物降解和吸水性土工合成材料（BioWAG）形式的创新土壤蓄水技术的基础。我们通过三年的田间试验分析了 BioWAG 对植物植被和环境的影响。此外，还分析了生物量增加、减少干旱效应和生物降解机制。天然废纤维具有积极影响，因为它们在生物降解过程中将易于获得的养分释放到土壤中。BioWAG 对草的生物计量参数有积极影响，使生物量增长了 430%。我们的结果表明，这是一种有效的废纤维管理方法，有可能制造创新的、环保的材料，符合循环经济的目标和用户的期望。
