Title

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

Abstract

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. Full details about this dataset can be found at https://doi.org/10.5285/990c54f6-5c92-4054-8bfa-953533a89149

Lineage

Samples processing (sampling, homogenisation, particle size reduction, storage, taking test portions, etc) was done following the recommendations of standards ISO/DIS 14820-2 and BS EN 15002:2006. The minimum amount of subsample taken from any sample type was no less than 0.5 kg. Each digestate sample received consisted on 5-10 kg of material, which has been sourced at the end of the process line in the AD plant, placed in jerry cans or barrels, allowed to cool down and then placed in suitable containers with ice for their transport (either by researchers or courier). Once received by Lancaster University, samples were placed in a cold room (<4C) and analysed as soon as possible. Normally, a subsample of selected digestates was sent out to an accredited external laboratory for determination of complementary analyses (mainly nitrogen forms). Prior to analyses of fresh digestate samples, no further pre-processing (e.g. sieving) was carried out. For determination on dried samples, the material was dried at 60/105C until constant weight, then milled and sieved to pass a 1 mm mesh and stored in zip bags and left under room temperature until further use. Each ash sample received consisted on 10-20 kg of material, which was sent by the producer and received by Lancaster University. From each sample type, a composite sub-sample was taken, air-dried, ground/milled sieved to pass a 1 mm mesh and placed in zip-bags left under room temperature until further use. This is what was considered as “fresh” sample. When the analytical method required fully dried samples, ashes were dried at 105C until constant weight. Normally, a subsample of selected ash was sent out to an accredited external laboratory for determination of complementary analyses (mainly phosphorus forms). Standard methods used for the analyses of the samples. pH was determined using a pH-meter, electrical conductivity was determined using a conductivity meter; nitrate, ammonium and phosphate was determined using an automated flow analyser; water soluble (WS) and Aqua Regia soluble (AR) elemental composition was determined using inductively coupled plasma optical emission spectrometry (ICP-OES) or microwave digestion; total Nitrogen and Carbon was determined using an elemental analyser.
