Enormous quantities of plant biomass are generated annually, as agricultural wastes. Lignocellulose is the main structural constituent of plants and represents the primary source of renewable organic matter on earth. This study was carried out to evaluate the lignocellulose composition, proximate and selected physicochemical characteristics of some selected plant-based substrates for biogas production. The substrates were: Corn cobs, Rice straw and Water hyacinth (Eichhorniacrassipes). They were collected, cut, dried for 72 hours at 320C, milled and subjected to hemicellulose, lignin and cellulose compositional analyses, using the standard Sox let extraction method. Standard methods were employed for proximate and physicochemical analyses. Results of the compositional evaluation showed that corn cob has the highest percentages of cellulose (42.0%), while extractives content was least (2.18%) in Rice straw. For the proximate analysis, the percentage carbohydrates (24.22) and ash (24.40) were highest in rice straw, while fat content  had the least values of 0.65%  recorded in corn cobs. The results of the physicochemical analysis showed that Rice straw had the highest values of TS (94.55%) and phosphorus (928.57mg/kg), Corn cob had the highest TVS (85.53%) and organic carbon (50.46%) while Water hyacinth recorded the highest Nitrogen content (2.33%). They are good substrates for energy generation, and lignocellulosic biomass holds a huge potential to meet the current energy demand of the modern world. The knowledge of the lignocellulosic composition of the biomass would help in choosing appropriate pretreatment measures to achieve better hydrolysis which would translate to higher biogas yield.

De-weeding of streams and lakes occurs in Germany on a widespread level, mostly to ensure water runoff and to provide flood protection. But de-weeding also affects a range of stakeholders, who have their own reasons to support or oppose it. For the list of stakeholders identified, see chapter 4. As part of a project analysing the feasibility of using water plant biomass as a substrate for biogas production, we conducted a multi-method stakeholder analysis to evaluate stakeholders’ opinions about de-weeding. The results show a preference of all stakeholders, except those identifying with nature conservation, for aquatic de-weeding. Our findings also point to a lack of communication between stakeholders, resulting in biased opinions of the stakeholders against other stakeholders and starting points for conflict.

The aim of the work is to determine and analyse concentrations of individual biogas components according to the used raw materials based on plant biomass. The measurement is focused on biogas production depending on input raw materials like maize silage, grass haylage and rye grain. The total amount of plant biomass entering the fermenter during the measurement varies at around 40% w/w, the rest is liquid beef manure. The measured values are statistically evaluated and optimised for the subsequent effective operation of the biogas plant. A biogas plant operating on the principle of wet anaerobic fermentation process is used for the measurement. The biogas production takes place during the wet fermentation process in the mesophile operation at an average temperature of 40°C. The technology of the biogas plant is based on the principle of using two fermenters. It follows from the measured results that maize silage with liquid beef manure in the ratio of 40:60 can produce biogas with a high content of methane; this performance is not stable. At this concentration of input raw material, the formation of undesirable high concentrations of hydrogen sulphide occurs as well. It is shown from the results that the process of biogas production is stabilised by the addition of other components of plant biomass like grass haylage and rye grain and a limitation of the formation of hydrogen sulphide occurs. It follows from the results that the maize silage should form about 80% w/w from the total amount of the plant biomass used.

Methane Fermentation

One of the most effective technologies involving the use of lignocellulosic biomass is the production of biofuels, including methane-rich biogas. In order to increase the amount of gas produced, it is necessary to optimize the fermentation process, for example, by substrate pretreatment. The present study aimed to analyze the coupled effects of microwave radiation and the following acids: phosphoric(V) acid (H3PO4), hydrochloric acid (HCl), and sulfuric(VI) acid (H2SO4), on the destruction of a lignocellulosic complex of maize silage biomass and its susceptibility to anaerobic degradation in the methane fermentation process. The study compared the effects of plant biomass (maize silage) disintegration using microwave and conventional heating; the criterion differentiating experimental variants was the dose of acid used, i.e., 10% H3PO4, 10% HCl, and 10% H2SO4 in doses of 0.02, 0.05, 0.10, 0.20, and 0.40 g/gTS. Microwave heating caused a higher biogas production in the case of all acids tested (HCl, H2SO4, H3PO4). The highest biogas volume, exceeding 1800 L/kgVS, was produced in the variant with HCl used at a dose of 0.4 g/gTS.

Fossil fuel demand growth in and price fluctuation, depletion resources and supply monopolize, climate change is forcing the restructuring of energy and other industrial and transport area, seeking for renewable energy sources. Using phytoremedial methods in biomass engineering, there is a possibility to create a sustainable method of biomass growth in mid-low contaminated sites soil system. Main aim of the research was to assess the oil-contaminated soil treatment herbaceous plants and their subsequent use for biogas production in order to create a closed cleaning and plant biomass utilization cycle. After the evaluation of the biogas yield and energy conversion efficiency performance it was found that all of the selected herbaceous plant biomass is suitable as raw material for the production of biogas. The biogas potential of selected plants ranged from 377.2 to 822.9 l/kg dry organic matter with an energy value ranging from 7.1 MJ/kg to 17.1 MJ/kg.

Degraded lands are potential areas for obtaining biomass which can serve as an energy source after its conversion into biogas. Thus, the studies on biogas production from maize and cocksfoot biomasses obtained from degraded soil supplemented with additions of new zeolite substrate (Z-ion as the nutrient carrier) and on arable soil (reference soil) were carried out during batch digestion tests. It was found that the biogas and biomethane potentials and specific energy of the test species growing in degraded soil enriched with Z-ion additions (1% and 5% v/v in the cases of cocksfoot and maize, respectively) did not differ significantly from the values of these parameters that were found for the plants growing in arable soil. The application of Z-ion to the degraded soil (especially in a dose of 5% v/v) resulted in an increase in the nitrogen content and decrease (below the lower optimum value) in the C/N ratio in the plant biomass. However, these changes did not negatively influence the final values of the biogas or methane potentials or the specific energy found for the maize biomass. Therefore, the study results indicated the usefulness of Z-ion substrate for improving the growth conditions for energy crops in degraded soils and, as a consequence, obtaining a plant feedstock suitable for the digestion process.
