Emission Control: Methods and Technologies for Agriculture (ECOMETA)

The project is aimed at development of technologies and methods for achieving an environmentally sustainable livestock production with strongly reduced impact on air quality in terms of odor, ammonia and bioaerosols. To achieve this, the project develops key abatement technologies with the highest reduction potential: end-of pipe air treatment and field application technology. Two types of air cleaning will be developed,

1) a hybrid biological-chemical technology and

2) a new chemical technology based on aqueous ozone. For slurry application, a new low-emission software technology is developed for shallow injection and pH control balanced to meet nutrient demand. To support the management and implementation of the technologies, the project includes development of on an optical sensor for NH3, a lab-on-a-chip NH3 detection device, and a software sensor for bio trickling filter control. Since the technologies are expected to be implemented in a new emission based regulation system, scientific gaps are also filled with respect to reference methods for this purpose.

These gaps include

1) a new odor assessment method based on analytical-chemical odorant measurements to provide reliable assessment of odor emission reduction, identification of a suitable reference method forassessing emissions from open area sources,

2) a new method for assessing nitrogen loss based on the N-to-K ratio aimed mainly at naturally ventilated livestock buildings (supplemented by an NMR sensor for measurement of N and K),

3) a methodology to test for bioaerosol risk and 4) a newly developed soil index for infiltration in relation to gas emissions. These reference methods will also be highly relevant in development of technologies and development/verification of sensor technologies.
