A recent study led by the University of Copenhagen (UCPH) atmospheric chemistry professor, Matthew Stanley Johnson brought to the spotlight, a new method devised by researchers to eradicate low-concentration methane from air

A new Methane Eradication Photochemical System (MEPS) reaction chamber, comprising an elongated metal box with heaps of hoses and measuring instruments, was built. Using chlorine and energy from light, researchers were successful in removing methane from air at a greater speed and efficiency compared to its natural decomposition rate in the atmosphere. Inside the box, a chain reaction of chemical compounds takes place, which breaks down the methane and removes a large portion of the gas from air.

"Methane decomposes at a snail's pace because the gas isn’t especially happy about reacting with other things in the atmosphere," explained Johnson. "However, we have discovered that, with the help of light and chlorine, we can trigger a reaction and break down the methane roughly 100 million times faster than in nature."

The Intergovernmental Panel on Climate Change (IPCC) has determined that reducing methane gas emissions—which are considered to be 85 times more potent of a greenhouse gas than CO2—will immediately reduce the rise in global temperatures. 

With the development of their new MEPS reaction chamber, the researchers plan to connect the device to the ventilation system in a livestock barn, where it will behave as a methane cleaner. A 40 ft shipping container will soon arrive at the Department of Chemistry and will become a larger prototype of the reaction chamber that the researchers built in the laboratory. The UCPH spin-out company Ambient Carbon, started and now headed by Johnson is currently developing the MEPS technology and plans to make it available to society in the near future.

As part of its innovative strategy to safeguard poultry production, Thailand-based Charoen Pokphand Foods (CP Foods) recently adopted the compartment scheme, thereby assuring disease-free poultry operations

The compartment system involves implementing strict biosafety and disease surviellance standards to maintain a closed-farm environment. To minimise the risk of diseases like Avian Influenza (AI) and Newcastle Disease (ND), veterinary specialists carry out regular pathogen tests for bird flu, Salmonella and the Newcastle virus. Through this initiative, the company highlights the importance of food safety both for raw and cooked products.

The disease control strategy of the compartment system is based on four pillars including, rigorous biosecurity measures, proactive bird flu surveillance, specific disease control within farms and surrounding areas, and a traceability system to monitor the food chain. By employing advanced closed house facilities comprising an evaporative cooling system, CP Foods leverages artificial intelligence (AI) and IoT for week-long animal health monitoring, thus significantly reducing disease risk through minimal human contact.

The implementation of this system across its poultry farms has greatly helped in raising Thai poultry standards through knowledge transfer, contract farming, and standardised disease prevention measures. Besides improving the overall resilence of the Thai poultry sector and economy, the implementation of the compartment system also enhances farm yields and income stability for farmers.
