Physico-chemical characterization of anaerobic digestate and biomass ash derived from UK bioenergy production

This dataset contains nitrogen data from nitrate, ammonium and nitrite, total nitrogen and carbon data, and elemental composition data from anaerobic digestate and biomass ash from UK bioenergy production. Anaerobic digestate was sampled 8 times from different industrial scale plants across the UK between January 2015 and January 2018 and biomass ash was sampled in January 2015 and June 2016. Anaerobic digestate was sourced from segregated food waste (mainly household waste), pig slurry, maize silage, vegetables waste, sweet corn waste, aerobically treated food waste, food manufacturer waste and other biodegradable sludge from within the UK. Biomass ash, both fly and bottom ash, from virgin and recycled wood was sourced from three sites within the UK and one from Spain. All laboratory analyses were undertaken at Lancaster University using standardised methods. The data were collected as part of the research grant, Developing a suite of novel land conditioners and plant fertilizers from the waste streams of biomass energy generation. The research was funded by NERC, award NE/L014122/1.

本数据集涵盖英国生物能源生产过程中产生的厌氧消化液（anaerobic digestate）与生物质灰（biomass ash）的相关分析数据，具体包含硝酸盐、铵盐、亚硝酸盐态氮数据、总氮与总碳数据，以及元素组成数据。厌氧消化液于2015年1月至2018年1月期间，从英国境内多家不同工业规模的处理厂采集了8批次样本；生物质灰则分别于2015年1月和2016年6月完成采样。厌氧消化液的原料涵盖英国境内的分类餐厨垃圾（主要为生活垃圾）、猪粪浆液、玉米青贮饲料、蔬菜废弃物、甜玉米废弃物、好氧处理餐厨垃圾、食品加工厂废弃物及其他可生物降解污泥。生物质灰包括飞灰与底灰，原料为原生木材与回收木材，采样点包含英国境内3处及西班牙1处。所有实验室分析均在兰卡斯特大学（Lancaster University）采用标准化方法完成。本数据集采集自一项名为"基于生物质能源生产的废弃物流开发新型土壤调理剂与植物肥料套装"的研究资助项目，该研究由英国自然环境研究理事会（NERC）资助，项目编号为NE/L014122/1。
