“…In Poland, it has been adopted to classify the type of biogas based on substrates used for its production, which means that the following types of biogases are in operation: landfill, sewage sludge, agricultural, other as well as municipal biogas, which has been gaining in popularity in recent years. Landfill gas (LFG) produced in waste deposits is characterised by a diverse chemical composition resulting from the deposited waste's morphology [4]. Due to the content of the main parameters, which are methane (40-60%) and carbon dioxide 25-45%, as a type of greenhouse gas, it is a potential threat to the environment and people.…”

The production of biogas from biodegradable waste generated in all sectors of the economy in Poland is a key issue for the diversification of energy sources and climate neutrality. The biogas balances presented in the literature based on bio-waste often contain overly optimistic data, which in reality only represent the theoretical potential of biogas in Poland. The pragmatic approach presented in this study fills a gap in research by presenting a technical balance of biogas (real potential) that can be realistically achieved. The objective of the work was to perform a biogas balance in the context of electricity and heat generation in cogeneration units. The tests made it possible to estimate the technical potential of biogas, depending on the source of its generation, the possibility of its conversion to biomethane and biohydrogen and the methods of its use. The research results showed a 30% increase in biogas potential on an annual basis compared to the current state, resulting in a 29% increase in electricity production and a 28% increase in heat production. The technical potential of biogas was estimated at 2186.62 million m3, which would allow for the production of 4627.06 GWh of electricity and 1869.64 TG of heat. The technical balance of biogas and the potential energy production can serve as input material for developing plans and strategies for the development of renewable energy sources in Poland. The work is consistent with the issues of balancing the renewable energy resources from biogas and the methods of conversion into other energy carriers using sustainable energy transformations in order to optimise energy production processes.

“…The final waste disposal sites contribute globally with approximately 5 % of the global generation of greenhouse gases (GHG), since these emissions that begin during the operation stages continue for many years after the closure or abandonment of the final disposal site, which represents risks to the environment and to the health of the people who inhabit their environment [9]. It has been calculated that in 2020 methane emissions from sanitary landfills and dumpsites in Mexico generated 24.67 Mt CO2 equivalent, being the second country in Latin America with the highest emission rate of this greenhouse gas from landfills [11].…”

“…Greenhouse gases (GHG) are those that trap heat in the atmosphere and that generate a series of environmental impacts such as global warming and, as a consequence, climate change [7], among these gases are included carbon dioxide, methane and oxide nitrous [11]. Methane and carbon dioxide are the two most important greenhouse gases, although the lifetime of both in the atmosphere is different (12 years for CH4 and between 50 and 200 years for CO2), however the difference lies in the warming power and that methane when reacting in the atmosphere becomes CO2 and water, reinforcing the global warming potential through the greenhouse effect [17].…”

The Abandoned Sanitary Landfill of the City of Veracruz, located to the north of the municipality, was built in the year 2000 and operated according to the regulations in force at the time, for a useful life of 10 years. However, it continued its operation irregularly, collapsing and becoming a controlled final disposal site that was closed by the state environmental authorities in 2019. Through the use of Google Earth satellite images using multicriteria techniques, it was determined that it has an area of 167 228 m² and an accumulated volume of waste of 1 505 052 m³. The Mexican Biogas Model 2.0 was used to estimate the generation of biogas that until the year 2023 was a total of 2 898 064 tons of biogas, and with the help of the methodology for the greenhouse effect calculation for urban solid waste, it was determined that in this same period a total of 2 522 057.3 tons of carbon dioxide, 1 162 154.8 tons of methane, and 47 115.9 tons of nitrous oxide were emitted. This represents a total of 47.5 Mt CO2 eq., which underscores the importance of minimizing greenhouse gas emissions and their impact on the environment due to global warming of the atmosphere, especially in the coastal ecosystem where the municipality of Veracruz, Mexico is located.

“…Analysis of the current state of utilization of industrial and municipal waste [16,22] shows that technologies are required that allow for solving a set of problems. In particular, it is necessary, along with waste disposal, to effectively expand the raw material base, reduce the anthropogenic load on the environment, and increase the area for beneficial use.…”

Combustion, Pyrolysis, and Gasification of Waste-Derived Fuel Slurries, Low-Grade Liquids, and High-Moisture Waste: Review

2022

The article discusses the modern achievements in the field of thermal recovery of industrial and municipal waste. The average accumulation rate and calorific value of typical wastes were analyzed. The focus is on the opportunities to exploit the energy potential of high-moisture waste, low-grade liquid components, and fuel slurries. We consider the relevant results in the field of combustion, pyrolysis, and gasification of such fuels. The main attention is paid to synergistic effects, the influence of additives, and external conditions on the process performance. Vortex combustion chambers, boilers with burners, and nozzles for fuel injection, grate, and fluidized bed boilers can be used for the combustion of waste-derived liquid, high-moisture, and slurry fuels. The following difficulties are possible: long ignition delay, incomplete combustion, low combustion temperature and specific calorific value, high emissions (including particulate matter, polycyclic aromatic hydrocarbons), fast slagging, and difficult spraying. A successful solution to these problems is possible due to the use of auxiliary fuel; boiler modifications; oxy-fuel combustion; and the preparation of multi-component fuels, including the use of additives. An analysis of methods of waste recovery in the composition of slurries for fuel gas production showed that there are several main areas of research: pyrolysis and gasification of coal–water slurry with additives of oil waste; study of the influence of external conditions on the characteristics of final products; and the use of specialized additives and catalysts to improve the efficiency of the pyrolysis and gasification. The prospects for improving the characteristics of thermochemical conversion of such fuels are highlighted.
