“…1. The thermograms broadly revealed three main stages of decomposition with the highest mass loss experienced between approximately 600 and 873 K. It is noteworthy that the pyrolysis temperature for most biomass resources lie within this temperature interval [17,19,21]; here a wide variety of volatile organic species are liberated from the decomposition of the main components, lignin and polysaccharides, as identified in Table 1. The earliest decomposition stage corresponds to moisture evaporation and liberation of light organic volatiles, while the trailing stage indicates lignin decomposition.…”

“…It is also noteworthy that the bio-char being relatively high in C and N contents could serve as a medium for soil fertility improvement and carbon sequestration. In comparison to activated carbon the butane activity (indirect measure of adsorption of alkane) for the bio-char is much lower and this may be attributed to a low surface area (3.1 m 2 /g) arising from a relatively less intensive thermal treatment [17].…”

“…Bio-char was collected at the other end of the reactor and yield recorded. Gas yield was determined by difference [17]. However, due to the limited amount of BSG sample the pyrolysis experiments could not be performed in replicates and other temperature values.…”

“…Bio-char samples were dried in an oven at 104°C for 24 h prior to analysis. The physico-chemical properties for the bio-char were determined as described in Section 2.2 and further analyses as stated in a previous publication [17]. The butane activity (BA) was determined according to ASTM D5742-95.…”

“…The biochar is a viable source of energy which may be exploited as fuel for heating applications and/or co-firing purposes. In addition, it could find significant use in promoting sustainable agricultural practices and environmental management issues as carbon sequesters, soil amendment media and adsorbents [16][17][18].…”

A B S T R A C TBrewer's spent grains, major by-products of the beverage industries, were obtained from a Nigerian brewery and subjected to pyrolysis at 500°C. Analytical pyrolysis (Py-GC/MS) was conducted on the original BSG, extractivefree BSG and BSG CH 2 Cl 2 extract. There was a marked difference in the concentration of levoglucosan between the extractive-free BSG (40.5%) and the original BSG (11.5%). The Py-GC/MS detected significant amount of palmitic and oleic acids in the three samples. Prior to pyrolysis, the extractives content were isolated through methanolysis, transesterified and subjected to GC/MS analysis. The analysis revealed the presence of linoleic, oleic and palmitic acids in an appreciable quantity. The BSG and its biochar were also characterised according to Fourier transform infrared and Raman spectroscopic, and thermogravimetric analyses alongside some conventional physico-chemical analysis. The total crystallinity and condensation indices were evaluated from specific FTIR spectra peaks so as to monitor structural transformations in the bio-char. Kinetic data were deduced from TGA measurements and it was apparent that thermal decomposition of BSG is better modelled as a multi-step reaction mechanism. The nitrogen content of the bio-char was relatively high making it a suitable feedstock for the production of in situ nitrogenised activated bio-carbon. There was a significant variation between the structural configuration of the original BSG and the bio-char as revealed by the change in the value of the condensation index as well as the cellulose crystallinity content. It may thus be concluded that the BSG biomass would be a viable feedstock for thermal decomposition and other valorisation processes.

Dairy operations constitute ∼2.5% of annual U.S. greenhouse gas (GHG) emissions, making dairies one of the largest sources of industrial GHG emissions. We are developing a novel, integrated system to achieve a net reduction in dairy GHGs while producing value-added materials and products. This integrated manure-to-commodities system converts dairy manure to bioenergy, sequesters carbon by converting volatile fatty acid-rich fermenter supernatant to bioplastics, and utilizes anaerobic digester (AD) and polyhydroxyalkanoate (PHA) reactor effluents to produce algae that can be harvested and internally recycled to enhance PHA production and sequester carbon. A decision-making tool is being developed for the integrated system that quantifies net GHG reduction, carbon sequestration, nutrient management and economics
