**Ammonia emissions** are harmful to natural habitats and our rivers and lakes, as well as to human health, with 87% of the UK's ammonia emissions coming from farming. The Government has committed to reducing ammonia emissions by 16% reduction of 2005 levels by 2030\. The project proposes a solution to **minimalize ammonia** (and other forms of "unused nitrogen") by the combination of two products, _**engineered biochar**_ and _**ply matting**_. Separately, both have a competition to a greater or lesser extent, but the final product has no direct competition due to the specific nature of production (using NH3-loaded feedstock for the char) and the purpose of binding NH3 and other harmful compounds while sequestering carbon. **Biochar** is considered as a double green revolution, serving both carbon sequestration (storage of carbon in the soil and reduction of carbon in the atmosphere) and soil amendment purposes. After some chemical or physical activation, biochar can be used as an excellent absorbent/adsorbent material. In combination with **geotextiles**, biochar can be used for the production of **absorption ply mats** used in different **agricultural practices**. Parallel to the R&D works (biochar production from agricultural waste streams via pyrolysis, fabrication and testing of ply absorption mats "prototype", additional desk studies will be performed including: (1) Literature review for biochar production (from biomass and chicken litter) and its engineering (activation for absorption studies); and (2) Assessment of scaling up routes ("prototype to product") and assessment of the potential market.

**氨排放**对自然栖息地，我们的河流和湖泊以及人类健康有害，其中87％的氨排放来自耕种。政府已承诺将氨排放量减少到2030年的2005年降低16％。该项目提出了一种解决方案，以通过两种产品的组合（_ **工程生物炭** _ _ and _ ** ply Matting ** _________________________________________________）提出了一种解决方法，以**将氨**（和其他形式的“未使用氮”）最小化。另外，两者都在或多或少地竞争，但是由于生产的特定性质（使用NH3负载的原料用于CHAR），最终产品没有直接的竞争，并且在隔离的同时绑定NH3和其他有害化合物的目的碳。 **生物炭**被认为是一场双绿色革命，既有碳固存（在土壤中储存碳和大气中碳的还原）和土壤修正案的目的。经过一些化学或物理激活后，生物炭可以用作出色的吸收/吸附剂材料。结合**土工布**，生物炭可用于生产**在不同**农业实践中使用的**吸收层**。与R＆D作品平行（通过热解，制造和测试层吸收垫“原型”的生物炭生产“原型”，将进行其他台式研究，包括：（1）生物炭生产（来自生物量和鸡肉垃圾）和鸡肉垃圾）和它的工程（用于吸收研究）和（2）评估扩展路线（“产品原型”）和潜在市场的评估。
