WATER & WASTE TREATMENT
By transforming emissions from waste into resources, valorisation helps cut pollution while adding economic value. Scaling these solutions is key to reducing emissions and enabling a circular, climate-resilient economy
NO2, known as a precursor pollutant, plays a
key role in the formation of ground-level ozone, which harms humans. Exposure to NO2 increases inflammation of the airways and reduces lung function, particularly in vulnerable populations. Given its prevalence in urban and industrial environments, there is a growing need to mitigate its impact. A major NO2 source is nitric acid production
for fertilisers. Here, pollution can become a resource, converting airborne NOx into usable plant nutrients. One innovation is R-Leaf by Crop Intellect, a
and reducing GHG emissions, valorisation can be used to protect human health. Nitrogen oxides (NOx), which include nitrogen dioxide (NO2) and nitric oxide (NO), are by-products of agriculture, electricity generation, industrial activities and residential combustion. These gases pollute the air and have significant respiratory impacts.
photocatalyst that captures airborne NOx. When combined with nitrogen-fixing bacteria, these pollutants are converted to plant- available nitrates. Trials show potential to cut synthetic fertiliser use by 50 per cent while raising wheat yields by 5 per cent. A solution can also be found at the source
of the problem, through the use of zeolite technology. Zeolites, composed of aluminium, silicon and oxygen, have highly porous structures that make them effective in absorbing nitrogen oxides. Their large surface
area, intricate channels and high thermal and hydrothermal stability allow for the efficient capture of NOx, for repurposing. At Krajete, we are applying this concept by
using zeolite technology to capture nitrogen oxides and convert them into valuable resources such as fertiliser. This technology can reduce emissions to as low as 1 ppm. Power plants, another major NOx emitter,
can also use zeolite-based systems to remove NOx from flue gases and convert them into industrial-grade nitrates, while in the chemical manufacturing sector, captured nitrogen oxides can be repurposed into fertilisers or other useful chemical products. Through chemical, biological, or hybrid
methods, industries can repurpose greenhouse gases into useful products, reduce reliance on virgin materials, and promote sustainability. Learn more about Krajete’s innovative gas
