“…Table 1 shows the proximate analysis of both PL and lignocellulosic biomass feedstock. According to the referred studies, the physico‐chemical properties of PL significantly affect the convenience of feedstock to burning, energy recovery efficiency, exhaust gaseous emission, and slagging, fouling, and agglomeration 11,22 . PL generally includes rice husk and sawdust combined with predominantly fecal matter and with a lesser amount of feather and feed residue.…”

“…In general, the proximate and ultimate characteristics create problems in maintaining steady and complete combustion of PL alone. 11 The concentration of alkali metals after incineration in remaining PL ash such as sodium oxide, potassium oxide, and the excessive amount of chloride results in a high potential for slagging, fouling, and corrosion compared to the conventional biofuels resources. Combustion temperature arrangements and feedstock blend preparation combining PL with fossil fuel frequently used method to prevent agglomeration and alkali metal deposited on heat exchange surfaces.…”

Broiler chicken industry generate different kinds of organic wastes mainly poultry litters (PL), which presenting high energy potential, but significant incineration burdens due to the mineral compositions. In the present study, the combustion potential of PL and locally available biomass co‐combustion candidates were evaluated based on proximate, ultimate, ash constitute, and exhaust gas emission. High heating values measured for PL samples were in the range of 13.5–14.6 MJ/kg and low heating values were 12.9–13.6 MJ/kg, respectively. The ultimate analysis result of PL was as follows; C (46.5 ± 1.3%), O (44.8 ± 0.7%), H (3.6 ± 0.3%), N (3.9 ± 0.3%), and S (0.9 ± 0.1%). Ash deposit challenging minerals were abundant in PL, in contrasting to the lignocellulosic biomass; wood residue (WR), hazelnut shell (HS), corn stalk (CS), and giant reed (GR), which can serve mitigation potential. High nitrogen and sulfur concentrations in PL had significantly increased the NOx and SO2 emissions but confirming related standards. Despite the high exhaust gas and ash emissions, the energy recovery practices of PL co‐combustion with lignocellulosic biomas allow environmentally safe management option for PL.

Poultry litter (PL) is one of the drier and bulkier manures produced in intensive agriculture. Land spreading is considered the most common treatment option for PL; however, this causes large atmospheric greenhouse emissions and consequently a high negative environmental impact. PL has several factors that limit its sustainable use as an energy source, and thus there is still a need for more studies about sustainable waste management. The paper aims at: (i) proposing sustainable pathways in order to maximise the PL valorisation process, based on previous experiences described in the literature; and (ii) showing the advantages of reforming poultry farms into biorefineries in Cuba. Combinations of techniques are used to increase PL valorisation, but only by modulating the theoretical data has an improvement occurred. In this work, pathways for thermo‐ and bioconversion processes are proposed which involve four major technologies for converting PL into useful energy and fertiliser, being pyrolysis/gasification, hydrothermal carbonisation and anaerobic digestion as key conversion technologies. Including technologies for nutrient recovery in the proposed pathways would allow better agricultural applications. The treatment of PL in biorefineries in Cuba would have a positive impact on the economy through income generation and savings resulting from reductions in imports (i.e. fossil fuels and agrochemicals), employment creation, improved living conditions and development in rural communities. Future studies should be aimed at evaluating the various proposed pathways in order to maximise the PL valorisation process, in addition to a marketing study of the products generated through the biorefineries at poultry farms. © 2020 Society of Chemical Industry (SCI)
