“…The thermochemical conversion process is a readily available technology for converting oilseed fruits into biofuels and is commonly employed for converting them into biofuels with a high heating value. 93,94 Biomass thermochemical conversion includes a great number of processes -for example, direct combustion, pyrolysis, oxy-fuel combustion, gasification, and transesterification. [95][96][97] Figure 2 shows an overall schematic of the thermochemical processes undergo oleaginous biomasses and the generated products.…”

The characterization of the physical-chemical properties and the thermal behavior of oilseed fruits for biofuels production has gained interest in the scientific community and society more generally, in particular with regard to their use as partial replacements for fossil fuels and for the possible reduction of air pollutants that cause problems for human health, animals, and plants. These oilseed fruits, which are rich in lipids, triglycerides, fatty acids, carotenoids, and other greasy compounds, can be transformed into solid, liquid, and gaseous products by different thermochemical conversion processes (conventional combustion, pyrolysis, oxy-fuel combustion, gasification and transesterification). This review investigates the different oleaginous feedstocks commonly found in the forests and plantations of Brazil -for example, olive stones, palm fruits, babassu coconut, macauba fruits, tucumã seeds and soybeans, and the respective residues generated from biofuel production and manufacturing processes. The main opportunities and challenges associated with the use of biofuels produced from these oilseed fruits lie in the fact that internal combustion engines using fossil fuels do not need to undergo modifications and mechanical adaptations to operate, and there is no corrosion risk and / or deterioration of metallic parts. Biofuels produce less greenhouse gas, or their pollution is considered neutral. Finally, the native forests of Brazil and the world present a vast number of different oleaginous species that still need be studied because they have excellent potential to be used as biofuels, as they are renewable energy sources and are sustainably eco-friendly.

“…Taking eucalyptus, in TL, the percentage of biomass in the ecosystem, based on the land occupation, is 15.99% [14]. While the percentage of biomass in the ecosystem in another country, such as Portugal, was 8.8% in the year 2010 [23]. From the data in Table 1, one can also estimate the annual yield (productivity) of eucalyptus.…”

This paper assesses the potential of biomass energy resources in Timor-Leste (TL). Although other renewable energy sources are mentioned in this article, such as wind energy, solar energy, hydropower, bioenergy, including bioethanol and biogas, the main goal is to gather the data on biomass in TL and provide such data as useful information for a wide range of end-users. The current evaluation is based on various sources which include previous assessments on biomass and other renewable sources. The energy potential of biomass in TL apart that resulting from vegetation or flora and animals is also derived from agricultural waste, such as waste from rice, corn, and coffee. The analyses also include the contribution of agricultural waste, animal waste, and that from urban waste. The results from this article show that the potential of usable biomass energy in TL from forestry and agriculture is 1.68 × 106 toe/year, animal waste is 4.81 × 103 toe/year, and urban solid waste amounts to 9.55 × 103 toe/year. In addition, it is concluded that biomass alone can fully replace fossil fuels for electricity generation.

Bioenergy production from biomass and agricultural wastes has gained significant interest due to rising fossil fuel prices and their decrease in air pollutant emissions. This review paper evaluates the state-of-art for the several applications from cassava harvest residues and their use in bioenergy industry, using different thermochemical and biochemical processes. Regarding the great available literature for this biomass, several pretreatment techniques, including mechanical, chemical, biological, thermal, ultrasonic and wet explosion were observed. The use of cassava harvest residues for the biochemical pretreatments, for example, hydrolysis, fermentation and thermochemical processes, such as direct combustion, gasification, pyrolysis, fast pyrolysis and oxy-fuel combustion was also discussed. Therefore, studies are necessary in order to understand that the use of cassava residues in thermal processes can increase the viability of this feedstock for biofuels production and/or in power co-firing units. After extensive study, it was observed that informations are still lacking about the use of cassava harvest residues in other conversion processes, thus, new studies to discover more on the use of this biomass, in order to extend their application in the bioenergy market is encouraged.
