Jun 2, 2022 · This work is a life cycle assessment (LCA) of three RNG pathways with multiple feedstocks and technologies. The three pathways evaluated are anaerobic digestion (AD), thermal gasification (TG), and power-to-gas (P2G). AD generates biogas by breaking down organic matter in the absence of oxygen.

Feb 15, 2023 · Renewable natural gas (RNG) can be produced from landfill gas, wastewater sludge, and animal waste. Triple bottom line performance of waste-derived gaseous fuel was assessed using LCA and LCC. Animal manure-derived RNG production provides the best environmental performance.

Aug 15, 2021 · The LCA system boundary of RNG and LA production pathways using sludge, food waste, swine manure, and FOG. The LCA results are presented using two different functional units: We present life cycle GHG emission results 1) …

May 22, 2024 · The LCA aims to estimate the emissions associated with 1 MJ of RNG produced via AD and biogas upgrading. The study uses 1 MJ of RNG produced as the functional unit to facilitate easy comparison with other studies.

Feb 22, 2024 · The article discusses and contrasts different methods of producing RNG under the NGFW processes, with variations in the production pathways dictated by the types of waste feedstocks available. LCA-C and LCA-E were used to facilitate the discussion and comparison of different RNG-from-waste pathways.

RNG can be used as an alternative to fossil natural gas, while LA from waste 19 feedstocks can displace conventional LA production pathways (mainly from corn via fermentation). 20 Providing comprehensive life cycle GHG emissions of the combinations of waste feedstocks and products

Science-based and internationally accepted life-cycle assessment (LCA) is an effective tool for policy makers to make scientifically informed decisions on expanding renewable energy production from newly developed bioenergy technologies.

Using the internationally accepted LCA method, this study evaluated the syngas electricity produced via a distributed-scale biomass pyrolysis system called the Tucker Renewable Natural Gas (RNG) system (pyrolysis system developed by Tucker Engineering Associates, Locust, NC).

Using the LCA method, this study evaluated the synthesis gas (syngas) electricity produced via a distributed-scale biomass thermochemical conversion system called the Tucker renewable natural gas (RNG) system.

and connections for RNG production, detailed cost estimates for integration of the RNG producing equipment, capital expenses (CAPEX)(± 30%), operating expenses (OPEX), and life- cycle analysis (LCA) quantifying the carbon intensity of the product.
