The objective of this study was to examine the potential of poultry wastes to be used as feedstock in non-catalytic and catalytic fast pyrolysis processes, which is a continuation of our previous research on their conversion into biofuel via slow pyrolysis and hydrothermal conversion. Both poultry meal and poultry litter were examined, initially in a fixed bed bench-scale reactor using ZSM-5 and MgO as catalysts. Pyrolysis of poultry meal yielded high amounts of bio-oil, while pyrolysis of poultry litter yielded high amounts of solid residue owing to its high ash content. MgO was found to be more effective for the deoxygenation of bio-oil and reduction of undesirable compounds, by converting mainly the acids in the pyrolysis vapours of poultry meal into aliphatic hydrocarbons. ZSM-5 favoured the formation of both aromatic compounds and undesirable nitrogenous compounds. Overall, all bio-oil samples from the pyrolysis of poultry wastes contained relatively high amounts of nitrogen compared with bio-oils from lignocellulosic biomass, ca. 9 wt.% in the case of poultry meal and ca. 5–8 wt.% in the case of poultry litter. This was attributed to the high nitrogen content of the poultry wastes, unlike that of lignocellulosic biomass. Poultry meal yielded the highest amount of bio-oil and was selected as optimum feedstock to be scaled-up in a semi-pilot scale fluidised bed biomass pyrolysis unit with the ZSM-5 catalyst. Pyrolysis in the fluidised bed reactor was more efficient for deoxygenation of the bio-oil vapours, as evidenced from the lower oxygen content of the bio-oil.

Similipal Biosphere Reserve

Odisha being the coastal state of Indian sub-continent records a rich medicinal plant diversity in general and orchids in particular. Since time immemorial, these important plant resources remains in a neglected state leading to an alarming situation in near future. Virgin forests of Odisha spreading in areas like Gandhmardan Hills, Niyamgiri Hills, Deomali Hills, Mahendragiri Hills and Similipal Biosphere Reserve hoards rich orchid diversity enduring luxuriant growth. Out of 137 species of Orchids recorded so far, Similipal area alone harbours about 94 orchid species possessing high aesthetic and medicinal value. Unfortunately, the medicinal importance of orchids of this region has drawn least attention from both the scientific fraternity as well as general populace compared to their role in horticulture field. Orchid species of Odisha like Acampe carinata (Griff.) Panigr., A. praemorsa (Roxb.) Blatt. & McCann, Geodorum recurvum (Roxb.) Alston, Habenaria marginata Coleb., Rhynchostylis retusa (L.) Bl. and Vanda testacea (Lindl.) Rchb.f. are used to cure rheumatism, arthritis, dysentery, asthma and snake bite etc. However, the medicinal potentialities of these orchids are not so well exploited though they possess immense curative values. Further, as the forests of Odisha are experiencing various anthropogenic as well as abiotic pressures, many of the orchid populations are fast shrinking leading to their mass depletion. Realizing this, the current communication highlights the importance of 26 medicinal orchids very often used by the tribal populace of Odisha to get relief from various ailments. Concurrently, some major conservational strategies have also been projected.

Lignocellulosic Pretreatment

The shifting of dependence from conventional fuels to renewable fuels and its increased production to combat the energy, environmental, and geopolitical crises is a global concern. One of the viable and promising alternatives is liquid biofuel production using lignocellulosic biomass. Lignocellulosic biomass being the most abundant encompass cellulose, hemicellulose, and lignin.The intricate complex of hemicellulose and lignin around cellulose is the bottleneck in commercializing the biofuel process. To make the cellulose and hemicellulose more accessible for hydrolysis and valorise the underutilized lignin for platform chemical production, pretreatment becomes imperative. Various pretreatment methods such as physical, mechanical, chemical, biological, and enzymatic and their combinations are employed for the production of bioethanol. It should be stressed that each pretreatment is unique in its condition and in most cases are biomass specific. With the above view, this chapter aims at bringing out the understanding of lignocellulosic pretreatment with updated information in the field.
