Pioneering breakthrough made in Murcia: Pig farms with no bad odours or greenhouse gases
Asaja Murcia's pilot program has received an international award from 'World Finance'
Greenhouse gas emissions are one of the major battles of recent decades for all countries in the world. Emissions levels remain very high and solutions have been sought in practically all sectors, but livestock, which contributes nearly 10% of the CO2 emitted annually in the world.
With the aim of reducing pollution in the Mar Menor basin from farms, Asaja Murcia has launched a project that goes much further, since, in addition to eliminating nitrates, it fights odours, makes flies disappear and the waste does not emit greenhouse gases.
Neighbours who live near smelly farms are sure to glad at the developments in this field of eliminating bad odours. Pig farms are notoriously bad smelling and often offend those that live near by.
“This is about decarbonisation and we have been applying it for two years at Asaja with satisfactory results,” explains Félix Navarro, consultant for the agricultural organisation and co-founder of the Murcian biotechnology company Aurelian Biotech, which has developed the compound.
This development is based on zeolites, which are a material capable of stimulating the microbial flora of excrement and slurry, and generating beneficial bacteria that transform ammonia into ammonium, dissolving the slurry and eliminating odours immediately.
The treatment consists of sprinkling a kilo of Biaurelian in the pit where the animals’ excrement falls. The cost for an average farm of about 2,000 pigs is 150 euros per month. That’s about 40 cents per pig per year as the price to pay to eliminate the pollution from these farms.
The companies can even recover these costs, or at the very least mitigate them, since stopping CO2 emissions has an impact on obtaining carbon credits that the company can sell.
This innovative project, which aims to mitigate 33% of global emissions, or around 2.5 gigatons of CO2, has already received its first recognition. The London-based World Finance has awarded the project first prize in the category of best carbon reduction project in the livestock industry in 2024.
“The project is part of a broader strategy to reduce the impact of the agricultural sector in Murcia by implementing advanced technologies, improving farm processes and creating carbon credits specific to this industry,” says World Finance.
