Greenhouse Gas and Air Pollutant Emissions from Composting

open access: yesEnvironmental Science and Technology, 2023
Composting can divert organic waste from landfills, reduce landfill methane emissions, and recycle nutrients back to soils. However, the composting process is also a source of greenhouse gas and air pollutant emissions.

Greenhouse gas growth rates [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
We posit that feasible reversal of the growth of atmospheric CH 4 and other trace gases would provide a vital contribution toward averting dangerous anthropogenic interference with global climate. Such trace gas reductions may allow stabilization of atmospheric CO 2 at an achievable level of ...

Research on the Evaluation of Air Quality in Underground Coal Mines Based on a Generalized Contrastive Weighted Comprehensive Scale Index Method

open access: yesAtmosphere, 2023
In this study, an optimization model was established based on the generalized contrastive weighted comprehensive scale index method. This model gives the evaluation indicators of SO2, NOx, CO, and TSP.

The Characteristics of the After-Combustion in a Commercial CFBC Boiler Using the Solid Waste Fuel

open access: yesEnergies, 2022
A CFBC (Circulating Fluidized Bed Combustor) boiler for combusted SRF (Solid Refused Fuel) is designed for solid waste combustion and power generation. The boiler consumes about 200 tons/day of SRF and generates 60 ton/h of steam or 10 MWe in electricity.

Agricultural Greenhouses: Resource Management Technologies and Perspectives for Zero Greenhouse Gas Emissions

open access: yesAgriculture, 2023
Resource management in agriculture is considered a pivotal issue because greenhouse farming and agriculture-related activities generate about 10–29% of all global greenhouse gas emissions.

Hydrogen and formate production and utilisation in the rumen and the human colon

open access: yesAnimal Microbiome, 2022
Molecular hydrogen (H2) and formate (HCOO−) are metabolic end products of many primary fermenters in the mammalian gut. Both play a vital role in fermentation where they are electron sinks for individual microbes in an anaerobic environment that lacks ...

A review of trends and drivers of greenhouse gas emissions by sector from 1990 to 2018

open access: yesEnvironmental Research Letters, 2021
Global greenhouse gas (GHG) emissions can be traced to five economic sectors: energy, industry, buildings, transport and AFOLU (agriculture, forestry and other land uses).
