“…The presence of lignin in tomato plant remains interferes with the decomposition of organic matter and decreases the overall production of methane during anaerobic digestion [27]. Prior research has demonstrated that materials possessing a substantial amount of lignin exhibit a reduced ability to be broken down by biological processes and generate methane [27,32,64]. Hence, it is crucial to reduce the presence of tomato plants during the co-digestion of tomato wastes to maximise methane production or apply pre-treatment methods that will enhance tomato plants' degradability.…”

The agricultural industry produces a substantial quantity of organic waste, and finding a suitable method for disposing of this highly biodegradable solid waste is a difficult task. The utilisation of anaerobic digestion for agricultural waste is a viable technological solution for both renewable energy production (biogas) and waste treatment. The primary objective of the study was to assess the composition of biogas, namely the percentages of methane, carbon dioxide, ammonia, and hydrogen sulphide. Additionally, the study aimed to quantify the amount of biogas produced and determine the methane yield (measured in NmL/g VS) from different agricultural substrates. The biochemical methane potential (BMP) measurements were conducted in triplicate using the BPC Instruments AMPTS II instrument. The substrates utilised in the investigation were chosen based on their accessibility. The substrates used in this study comprise cattle manure, chicken manure, pig manure, tomato plants, tomatoes, cabbage, mixed fruits, mixed vegetables, dog food, and a co-digestion of mixed vegetables, fruits, and dog food (MVMFDF). Prior to the cleaning process, the makeup of the biogas was assessed using the BIOGAS 5000, a Geotech Analyser. The AMPTS II flow cell automatically monitored and recorded the volume of bio-methane produced after the cleaning stage. The data were examined using the Minitab-17 software. The co-digestion of mixed vegetables, mixed fruits, and dog food (MVMFDF) resulted in the highest methane level of 77.4%, followed by mixed fruits at 76.6%, pig manure at 72.57%, and mixed vegetables at 70.1%. The chicken manure exhibited the greatest levels of ammonia (98.0 ppm) and hydrogen sulphide (589 ppm). Chicken manure had the highest hydrogen sulphide level, followed by pig manure (540 ppm), tomato plants (485 ppm), mixed fruits (250 ppm), and MVMFDF (208 ppm). Ultimately, the makeup of biogas is greatly affected by the unique qualities of each substrate. Substrates containing elevated quantities of hydrogen sulphide, such as chicken manure, require the process of biogas scrubbing. This is because they contain substantial amounts of ammonia and hydrogen sulphide, which can cause corrosion to the equipment in biogas plants. This emphasises the crucial need to meticulously choose substrates, with a specific focus on their organic composition and their capacity to generate elevated methane levels while minimising contaminants. Substrates with a high organic content, such as agricultural waste, are optimal for maximising the production of methane. Furthermore, the implementation of biogas scrubbing procedures is essential for efficiently decreasing carbon dioxide and hydrogen sulphide levels in biogas. By considering and tackling these problems, the effectiveness of biogas generation can be enhanced and its ecological consequences alleviated. This strategy facilitates the advancement of biogas as a sustainable energy source, hence contributing to the attainment of sustainable development goals (SDGs).

The growing worldwide concern over the environmental impact of our heavy dependence on fossil fuels has provided impetus for biomass utilisation to produce fuels and chemicals. A cost-effective conversion technology stands as a challenge for biobased fuels and chemicals to be competitive with petroleum-derived products. This review provides an overview of the recent advances in the conversion technologies of biomass, which includes thermochemical and biochemical processes. With a plethora of conversion technologies available, the choice of suitable conversion technology depends on the biomass feedstock availability and the desired end-product. It is observed that present research is focused on the development of catalysts and optimisation of process parameters to improve the economics of conversion technologies. Efforts are also on towards utilisation of cheaper substrate, lignocellulosic biomass and CO 2 -sequestering algae. Though few technologies have reached the commercial stage, conversion technologies for lignocellulosic and marine biomass are still evolving. Further, much impetus is being given to process optimisation for deriving platform chemicals from biomass for value addition and sustainability of the biorefinery concept. Some key developments in these areas are presented in this review.

“…AD is one of the most popular ways of handling OFMSW because contamination risks are minimized and biogas, a renewable energy source, is produced in a controlled process that benefits the environment. More than 20,000 biogas plants have been built worldwide [8,9]. On the other hand, it is worth adding that digestate sludge from an agricultural biogas plant can also be reused to produce biodegradable materials.…”

Bioplastics are frequently utilized in daily life, particularly for food packaging and carrier bags. They can be delivered to biogas plants through a separate collection of the organic fraction of municipal waste (OFMSW). The increased demand for and use of bioplastics aimed at mitigating plastic pollution raises significant questions concerning their life cycle and compatibility with waste management units. Anaerobic digestion (AD) in OFMSW is a valuable resource for biogas production. In this work, the valorization of poly-L-lactic acid (PLLA) composed of food waste within the Biowaste to Bioplastic (B2B) Project framework was studied in laboratory and pilot-scale anaerobic liquid conditions. Taking into account that the addition of PLLA to biowaste can increase biogas production, we performed laboratory-scale anaerobic tests on food waste enriched with different molecular-weight PLLAs produced from food waste or commercial PLLA at a mesophilic temperature of 37 °C. PLLA with the highest molecular weight was subjected to AD on the pilot scale to further validate our findings. The addition of PLLA increased biogas production and had no apparent negative impact on the operation of the reactors used in the laboratory or on the pilot scale. Biogas production was higher when using PLLA with the lowest molecular weight. In the pilot-scale experiments, co-digestion of FW with PLLA increased biogas production by 1.1 times. When PLLA was added to the feed, biomethane was 8% higher, while volatile solids (VS) and total chemical oxygen demand (TCOD) removal were almost the same. Importantly, no effect was observed in the operation of the digesters.
