Production of renewable fuel and value-added bioproducts using pineapple leaves in Costa Rica

Recent Updates on the Conversion of Pineapple Waste (Ananas comosus) to Value-Added Products, Future Perspectives and Challenges

“…They found that the sodium hydroxide pre-treatment was not efficient in producing bioethanol from pineapple peels. Recently Chen et al [166] used anaerobic ethanol fermentation to produce bioethanol with pineapple leaves as raw materials. According to the authors, fermentation using Kluyveromyces marxianus managed to produce 2.1 tons of bioethanol.…”

Sustainable bioenergy solutions to enable development in low- and middle-income countries beyond technology and energy access

“…The breadth of feedstocks, conversion technologies and final energy vector covered in the SI articles showed the importance of understanding and addressing the interfaces between feedstock, technology, and demand. The SI articles by Azasi et al [6], Chen et al [8],…”

“…Karthikeya et al [12], Ordoñez-Frías et al [13], Ozonoh et al [14], Sekoai et al [16] showed how thermal, mechanical and chemical pre-treatment of biomass can help to overcome some of these challenges and improve the versatility of feedstocks. Chen et al [8], Karthikeya et al [12], and Sekoai et al [16] showed the high potential of advanced conversion technologies to produce hydrogens and alcohols, that have multiple applications including liquid biofuels for transport. The real cost and implementation of such bioenergy approaches is yet to be widely exploited even in advanced economies.…”

“…The SI articles investigating the technical feasibility and development of bioenergy [8,12,13,16,20] showed possible application of different conversion technologies and utilisation of feedstocks as well as the optimisation through pre-treatment for different types of feedstock and conversion pathways.…”

Optimization of Fermentable Sugar Production from Pineapple Leaf Waste (Ananas comosus [L.] Merr) by Enzymatic Hydrolysis

“…Current practices of processing the wastes are mainly in situ burning of pineapple waste, decomposition of pineapple residues, and removal before planting. The in situ burning method is quick and easy to carry out but not environmentally sound since burning can lead to groundwater and air pollution and also cause a fire (Chen et al, 2020). Excellent waste management must be practiced to minimize pollution to environments and convert the leaves into practical and economical products.…”
