Municipal solid waste collection and transport are functional activities in waste management, with a significant energy and carbon footprint and a significant effect on the urban environment. An issue related to municipal solid waste collection and transport is their regional and municipal implementation, affected by sorting and recycling strategies at local level. An efficient collection is necessary to optimize the whole recycling process. The present paper shows the results of an energy, environmental, and economic evaluation of a case study, analyzing the fleet used for municipal solid waste collection and transport in 10 municipalities in Central Italy. The current scenario was compared with alternative scenarios on the basis of some parameters for performance evaluation: vehicles’ energy consumption, carbon footprint, routes, and costs. Results show that for passenger cars, the alternative scenario based on an entire fleet of dual compressed natural gas (CNG) vehicles led to a reduction of the CO2 emissions (−2675 kgCO2eq) in the analyzed period (January–August 2019) and a reduction of the energy consumption (−1.96 MJ km−1). An entire fleet of CNG vehicles led to an increase of CO2 emissions: +0.02 kgCO2eqkgwaste−1 (+110%) for compactors (35–75 q) and +0.09 kgCO2eqkgwaste−1 (+377%) for compactors (80–180 q). Moreover, both categories report a higher fuel consumption and specific energy consumption. For waste transport high-capacity vehicles, we propose the installation of a Stop-Start System, which leads to environmental and energy benefits (a saving of 38,332 kgCO2eq and 8.8 × 10−7 MJ km−1kgwaste−1). On three-wheeler vehicles, the installation of the Stop-Start System is completely disadvantageous.

The analysis of scientific investigations makes it possible to make a conclusion about the usefulness of the generator gas as a fuel for internal combustion engines of mobile power generators. Under the conditions of agricultural production and in rural areas, the generator gas can be generated from biomass (wood, straw, corn stalks and other plant refuse). The paper recommends to use a gasifier of the reverse process for gas generation. The side of the recovery zone of the gasifier is 200 mm long, and the recovery zone is -70 mm high. The number of tuyere holes is 20, the diameter of the tuyere holes is 10 mm. The research was conducted in order to determine the effects of the produced generating capacity on generator gas and air consumption, as well as on emissions of greenhouse gases (CxHу and CО). The paper shows the nature of the effects of the produced generating capacity on generator gas and air consumption by the engine of a mobile power generator. As follows from the investigation, under the generating capacity, which corresponds to nominal electric generator charge, under the use of generator gas generated from wood CO emission is up to 25 times less, and CxHу emission is up to 9 times less as compared to gasoline fuel. While using the generator gas generated from straw, CO emission is up to 25 times less, and CxHу emission is up to 4 times less as compared to gasoline fuel. The paper also shows the results of the investigation as to the impact of the engine exhaust supply of a power generator engine into the combustion area of a gas generator on the power generator schedule, as well as on the dynamic pattern of the generated effective power.

“…Biogas generally contains 50-70% methane (CH 4 ), 25-50% carbon dioxide (CO 2 ), and 1-5% of hydrogen. The rates of these gases may vary depending on effects such as bacteriological, raw material stocking rate, water content, temperature, and feeding source [23]. For the most suitable combustion conditions to be realized in the cylinder, at least 50% of CH 4 , which is the most basic content of biogas, must be present [24].…”

The major aim of the research is to investigate the ability of biogas as an alternative fuel for gasoline-powered Spark Ignition (SI) engine. In this study, biogas/gasoline fuel mixtures containing different ratios of biogas, gasoline, and biogas were tested in an SI engine with an increased compression ratio at different engine loads and constant engine speed. According to the comparison with gasoline, the utilization of biogas generally decreased the Brake Thermal Efficiency (BTE), while the Brake Specific Fuel Consumption (BSFC) rose. The lowest BTE and the highest BSFC were obtained with 100% biogas. Compared to gasoline, a decrease of 16.04% and an increase of 75.52% were observed, respectively. On the other hand, the use of biogas has improved all emissions. The best emission values were obtained with 100% biogas. Compared to gasoline, Carbon monoxide (CO), HydroCarbon (HC), and Nitrogen Oxide (NOx) emissions decreased by 56.42%, 63%, and 48.96%, respectively. Finally, according to the results of the combustion analysis, the peak pressures were reduced with the utilization of biogas, and the position of the peak pressure shifted by 2° to 3° Crank Angle (CA). Compared to gasoline, the lowest pressure was obtained with 100% biogas, resulting in a reduction of approximately 24.69%.
