“…More recently, some authors have recommend harvesting S. perfoliatum to maximise biogas production when the dry matter content is specifically 26-28% [81] or 30% [88]. A variety of pre-treatments to increase biogas production have been applied prior to the anaerobic digestion of S. hermaphrodita: chemical hydrolysis [137], chemical and enzymatic hydrolysis [139][140][141], mechanical, chemical plus enzymatic hydrolysis [142], as well as various mechanical [138,143,144], thermal [32,[145][146][147], and thermochemical treatments [148]. Ensiling of S. hermaphrodita is common practice prior to anaerobic digestion [42,67].…”

“…Nowicka et al [148] combined the application of microwaves and sodium hydroxide on the mix of S. hermaphrodita silage and bovine slurry, obtaining 1311 dm −3 kg −1 oDM. Zieliński et al [147] compared the use of microwaves and hot water on S. hermaphrodita silage and cattle manure, producing maximum methane yields (at 150 • C, 15 min) of 590 dm 3 kg −1 oDM and 575 dm 3 kg −1 oDM, respectively. They developed two regression functions to calculate the methane and energy output for both treatments.…”

Current global temperature increases resulting from human activity threaten many ecosystems and societies, and have led to international and national policy commitments that aim to reduce greenhouse gas emissions. Bioenergy crops provide one means of reducing greenhouse gas emissions from energy production and two novel crops that could be used for this purpose are Sida hermaphrodita (L.) Rusby and Silphium perfoliatum L. This research examined the existing scientific literature available on both crops through a systematic review. The data were collated according to the agronomy, uses, and environmental benefits of each crop. Possible challenges were associated with high initial planting costs, low yields in low rainfall areas, and for Sida hermaphrodita, vulnerability to Sclerotinia sclerotiorum. However, under appropriate environmental conditions, both crops were found to provide large yields over sustained periods of time with relatively low levels of management and could be used to produce large energy surpluses, either through direct combustion or biogas production. Other potential uses included fodder, fibre, and pharmaceutical uses. Environmental benefits included the potential for phytoremediation, and improvements to soil health, biodiversity, and pollination. The review also demonstrated that environmental benefits, such as pollination, soil health, and water quality benefits could be obtained from the use of Sida hermaphrodita and Silphium perfoliatum relative to existing bioenergy crops such as maize, whilst at the same time reducing the greenhouse gas emissions associated with energy production. Future research should examine the long-term implications of using Sida hermaphrodita and Silphium perfoliatum as well as improve knowledge on how to integrate them successfully within existing farming systems and supply chains.

“…The experiments conducted so far have proved a positive influence of the microwave pretreatment-based technologies on the anaerobic digestion effectiveness [36,37]. The highest effectiveness has been observed with methane fermentation of biomass feedstock [38], microalgae [39], wastewater, and sludge [40].…”

Whey is a primary by-product of dairy plants, and one that is often difficult to manage. As whey processing units are costly and complicated, only 15–20% of whey is recycled for use in the food industry. The difficulties in managing waste whey are particularly pronounced for small, local dairy plants. One possible solution to this problem is to use advanced and efficient digesters. The aim of this study was to present an innovative multi-section hybrid anaerobic bioreactor (M-SHAR) design and to identify how microwave radiation heating (MRH) affects methane fermentation of liquid dairy waste (LDW) primarily composed of acid whey. The MRH reactor was found to perform better in terms of COD removal and biogas production compared with the convection-heated reactor. The heating method had a significant differentiating effect at higher organic load rates (OLRs). With OLRs ranging from 15 to 25 kgCOD∙m−3∙d−1, the M-SHAR with MRH ensured a 5% higher COD removal efficiency and 12–20% higher biogas yields.

“…Microwave heating has shown potential applications in biodiesel production through a transesterification reaction [ 8 ], syngas production via pyrolysis [ 9 , 10 , 11 ], food drying [ 12 , 13 ], plastic-polymer synthesis [ 12 ], composite reinforcement [ 14 ], extraction [ 15 , 16 ], and biogas production [ 17 , 18 , 19 ]. Microwave irradiation is used to intensify the rate of heating of any process faster than the conventional heating [ 20 ].…”

Prospects and Challenges of Microwave-Combined Technology for Biodiesel and Biolubricant Production through a Transesterification: A Review

et al. 2021

Biodiesels and biolubricants are synthetic esters produced mainly via a transesterification of other esters from bio-based resources, such as plant-based oils or animal fats. Microwave heating has been used to enhance transesterification reaction by converting an electrical energy into a radiation, becoming part of the internal energy acquired by reactant molecules. This method leads to major energy savings and reduces the reaction time by at least 60% compared to a conventional heating via conduction and convection. However, the application of microwave heating technology alone still suffers from non-homogeneous electromagnetic field distribution, thermally unstable rising temperatures, and insufficient depth of microwave penetration, which reduces the mass transfer efficiency. The strategy of integrating multiple technologies for biodiesel and biolubricant production has gained a great deal of interest in applied chemistry. This review presents an advanced transesterification process that combines microwave heating with other technologies, namely an acoustic cavitation, a vacuum, ionic solvent, and a supercritical/subcritical approach to solve the limitations of the stand-alone microwave-assisted transesterification. The combined technologies allow for the improvement in the overall product yield and energy efficiency. This review provides insights into the broader prospects of microwave heating in the production of bio-based products.
