Critical parameters in the life cycle inventory of palm oil mill residues composting [PDF]

, 2019
Palm oil mill's co-products (empty fruit bunch – EFB and palm oil mill effluent – POME) management is a matter of concern in Indonesia. Co-composting is a promising waste management practice that would allow a reduction of environmental impact and a ...

Waterfalls enhance regional methane emissions by enabling dissolved methane to bypass microbial oxidation

Communications Earth & Environment
River waters are significant sources of atmospheric methane whose local emissions increase with river slope and turbulence. However, when integrated regionally, the amount of dissolved methane released to the atmosphere is uninfluenced by local changes ...

Wetlands’ Methane Emissions

This research aimed to enhance the accuracy of methane (CH₄) emissions estimates from natural wetlands by integrating satellite observations and advanced modeling techniques. Wetlands are among the largest natural sources of CH₄. However, current estimates carry large uncertainties due to the spatial and temporal variability of wetland characteristics.

Quantification of methane emissions from typical natural gas stations using on-site measurement technology

Journal of Pipeline Science and Engineering
Natural gas transmission systems are the main source of methane emissions in the oil and gas industry. Methane, as the second most potent greenhouse gas, makes a strong contribution to climate change.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Methane emission from the Western Siberia’s wetland ecosystems in 2000–2050

Acta Biologica Sibirica
The interannual variability of methane emissions from wetland ecosystems of Western Siberia in 2000–2050 has been investigated. Calculations of CH₄ emission were performed using the approach, in which the total daily methane flux is determined by the sum

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

How to Understand and Promote Sustainable Dairy Development?

Animal Research and One Health, EarlyView.
ABSTRACT Sustainable dairy development is crucial for global food security, as it converts feed resources into nutrient‐dense human food while supporting soil fertility through manure recycling. Milk provides high‐quality protein and essential micronutrients, yet rising production demands have intensified challenges related to animal welfare and ...
