“…Recycling 2023, 7, x FOR PEER REVIEW 6 of 17 be noted that the energy generated resulted in 76.79 MWh/year for the minimum population, which was classified as the microgeneration distribution. It is worth mentioning that the study in [37] obtained a result of 450 kW for a population of 150,000 inhabitants under conditions similar to those considered in this article, indicating considerably more significant than those presented here.…”

“…Refs. [6,36,37] evaluated the economic viability of generating electricity from sanitary landfills and anaerobic reactors in the state of Minas Gerais. This study demonstrated that the state would benefit from the electrical energy generated: 15,400 MWh/year with an installed power capacity of 3200 kW generated by the OFUSW.…”

Evaluation of Biogas Energy from Co-Digestion of Organic Urban Solid Waste with Lime Mud

The elevated presence of organic material in Brazilian urban solid waste, along with mismanagement of its disposal, can aggravate environmental problems from greenhouse gas emissions to water and soil pollution. In parallel, the paper and cellulose industries consume considerable resources and produce important solid wastes, including lime mud. These urban and industrial realities present common ground, from which a little-studied alternative arises in using biogas electrical energy from the co-digestion of the organic portion of urban solid waste using lime mud. This intersection can reduce the environmental impacts associated with inadequate management and disposal of solid waste, providing industry financial economy resources and contributing to Brazilian energy grid diversification. The current study used economic–financial indicators to evaluate the proposal’s economic feasibility. The obtained results presented a minimum population of 165,200 inhabitants, generating 39,295.77 m3/year of methane, in order to enable a co-digestion proposal. The sensitivity analysis indicated that a population of 185,500 inhabitants would provide a 10-year payback, an energy rate of USD 0.139, and 44,124.49 m3/year of methane to supply the population with power. The net present value was USD 23,336.94, with an internal return rate of 14.71% and a levelized energy cost of 0.103 USD/kWh.

“…The use of a biodiesel-biogas fuel compression ignition engine was shown to have superior performance in terms of emissions [1], and such engines can be employed in the generation of electricity or cogeneration processes. The cogeneration of steam and electricity using biogas derived from pig manure and corn silage blends is an area of recent research [2] for which lifecycle aspects such as ozone depletion were examined for a variety of feedstocks, with a view to implement such processes on-site at pig farms. The micro-cogeneration of a compression ignition internal combustion engine using a lean homogeneous air/biogas mixture has been shown to be practicable for a company operating a mid-sized farm [3].…”

Purifying biogas can enhance the performance of distributed smart grid systems while potentially yielding clean feedstock for downstream usage such as steam reforming. Recently, a novel anion-pillared metal–organic framework (MOF) was reported in the literature that shows good capacity to separate acetylene from carbon dioxide. The present study assesses the usefulness of this adsorbent for separating a typical biogas mixture (consisting of methane, nitrogen, oxygen, hydrogen, carbon dioxide, and hydrogen sulphide) using a multiscale approach. This approach couples atomistic Monte Carlo simulations in the grand canonical ensemble with the batch equilibrium modelling of a pressure swing adsorption system. The metal–organic framework displays selectivity at low pressures for carbon dioxide and especially hydrogen sulphide. An analysis of adsorption isotherm models coupled with statistical distributions of surface–gas interaction energies determined that both CH4 and CO2 exhibited Langmuir-type adsorption, while H2S displayed Langmuir-type behaviour at low pressures, with increasing adsorption site heterogeneity at high pressures. Batch equilibrium modelling of a vacuum swing adsorption system to purify a CH4/CO2 feedstock demonstrated that such a system can be incorporated into a solar biogas reforming process since the target purity of 93–94 mol-% methane for incorporation into the process was readily achievable.
