“…A green biorefinery utilises green whole crops such as grasses and legumes for manufacture of chemicals, materials and fuels and for a sustainable production of value added products such as protein. 11 Lucerne is a valuable forage crop that is used for production of protein in the biorefinery, with the added advantages of reducing crop nitrogen fertiliser requirements due to its nitrogen-fixing ability. 12 Feedstock processing in a biorefinery consists of a mechanical fractionation process to generate a juice and a fibre fraction.…”

White clover could be a good candidate for protein production purpose in a biorefinery due to its high extractable protein content per kg DM. In order to maximise the protein production capacity, harvest should take place during early growth due to a decline in protein extractability with maturity. The final economy of the concept will depend on the value of the fibre after extraction of the protein. © 2017 Society of Chemical Industry.

“…fibre‐rich press‐cake), and these separated fractions can be subjected to a series of downstream processes to recover or produce valuable products (Kromus et al ., ; McEniry et al ., ). For example, lactic acid and amino acids can be extracted from the press‐juice fraction (Ecker et al ., ), while the production of thermal insulation boards from the separated press‐cake fraction has also been described (Grass, ). Another possible application for the press‐cake fraction is as a source of biomass fuel for thermal combustion.…”

In a Green Biorefinery processing green biomass, one possible application for the press‐cake fraction is as biomass fuel for combustion. In an industrial setting, the preservation of herbage as silage and its subsequent fractionation into press‐juice and press‐cake fractions represent the two major process steps in the utilization of green biomass. This study investigated (i) the effects of ensiling and fractionation on the chemical composition of three common temperate grassland species harvested at different stages of maturity and (ii) the suitability of the herbage of these species for thermal combustion. The high contents of ash, N, Cl and K in perennial ryegrass, cocksfoot and red clover, at both pre‐ and post‐ensiling, make these materials less suitable for combustion in certain applications. The loss of soluble/fermentable organic matter during ensiling increased the relative proportions of fibre, ash and N in the herbage, but these changes were relatively minor. In contrast, the substantial reduction in the concentration of compounds such as ash, N, Cl and K during fractionation improved the suitability of the press‐cake fraction for combustion compared with the parent material. Press‐cake prepared from later‐harvested grass herbage with lower ash, S and N contents would be more suitable for combustion.

“…Green biorefinery is another form of phase III biorefinery which has been extensively studied in the EU (especially Germany, Austria and Denmark) over the last 10-20 years [42,43]. It takes green biomass (such as green grass, lucerne, clover, immature cereals, etc.)…”
