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溶解度很高，不幸的是，这些肥料中的70%在几天内就会迅速从土壤中淋失，并在空气和地下水中受到污染，使作物只剩下20%的养分。市场上的几种产品被用来减少化肥的快速淋溶，使用缓释化学机制，并在化肥颗粒上涂上防水聚合物和蜡。目前，市场上的包膜肥料是使用以化石为基础的昂贵聚合物生产的，这导致最终产品的价格昂贵(是尿素价格的4-5倍)，这限制了这些包膜肥料的大量使用，并影响了使用非生物降解聚合物的效果，这种聚合物被发现是有毒的，并在土壤中积累。在Biotica有限公司，我们发明了一种植物基聚合物树脂来包衣肥料，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，减少淋洗造成的污染，并减少二氧化碳排放的化肥生产所消耗的能源。

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.
