Environmentally friendly new biodegradable plant-based polymer resin to coat nitrogen fertiliser for a controlled extended nutrients release.

农业应用占全球能源消耗的3%，其中2%用于生产尿素等无机肥料。由于这些肥料在水中的高溶解度，不幸的是，70%的这些肥料在几天内就从土壤中快速滤出，并以空气和地下水的污染形式流失，使作物只剩下20%的养分。市场上的几种产品通过使用缓释化学机制和在肥料颗粒上涂上防水聚合物和蜡来减少肥料的快速浸出。目前，市场上的包膜肥料是使用昂贵的化石基聚合物生产的，这导致最终产品的价格昂贵（尿素价格的4-5倍），这限制了这些包膜肥料的大量使用，以及使用被发现有毒且在土壤中积累的不可生物降解聚合物的影响。在Biotica有限公司，我们发明了一种植物基聚合物树脂来覆盖肥料，这种树脂具有成本效益和可生物降解性，可以将肥料在土壤中的使用寿命延长6个月。这将降低农民的最终成本，减少浸出造成的污染，减少肥料生产所消耗的能源，同时减少二氧化碳排放。

Agriculture applications are responsible for 3% of the energy consumed worldwide, 2% of these are used to produce inorganic fertilisers such as Urea. Due to the high solubility of these fertilisers in water, unfortunately, 70% of these fertilisers are leached fast from the soil in a few days and lost as pollution in the air and underground water leaving crops with only 20% of nutrients. Several products in the market were used to decrease the fertiliser fast leaching using a slow release chemical mechanism and by coating the fertiliser grains with water-resistant polymer and waxes. Currently, the coated fertilisers in the market were produced using a fossil-based expensive polymer which results in the expensive price of the final product (4-5 times the price of Urea), this limited the massive use of these coated fertilisers as well as concert about the effect of the use non-biodegradable polymer that was found to be toxic and accumulates in soils. In Biotica Ltd we invented a plant base polymer resin to coat fertilisers that is cost-effective and biodegradable and can extend the lifetime of fertilisers in soli for 6 months. This will decrease the final cost for farmers, decrease the pollution resulting from leaching and decrease the consumed energy for fertiliser production with less CO2 emission.
