DSM is a global science-based company with subsidiaries in health, nutrition and materials sciences. Stamicarbon, a subsidiary of DSM, is the global market leader in urea technology licensing. EU regulations forced Stamicarbon to reduce ammonia emissions from urea manufacturing by at least 90%. In 2008, Stamicarbon developed a breakthrough process using activated zeolites to adsorb ammonia and reduce emissions by 95% while also reducing urea dust by 99% and lowering ammonia consumption, for which they received a global patent.

1. Company Profile
 DSM is a global science-based company active in health, nutrition and materials. By
connecting its unique competencies in Life Sciences and Materials Sciences, DSM is driving
economic prosperity, environmental progress and social advances to create sustainable value
for all stakeholders. Stamicarbon is the global market leader in the development and licensing
of urea technology. Stamicarbon is the licensing subsidiary of DSM.
Innovation Challenge
 EU regulation forced Stamicarbon, hence DSM, to reduce their ammonia emission from their
urea manufacturing process with at least 90%.
Outcome (2008) – Breakthrough in Ammonia Emission Abatement
 A breakthrough process able to reduce the ammonia emission by 95% and urea dust by 99%
was developed. The process removes the ammonia through adsorption using activated
zeolites. Adsorbents are injected into the airstream and separated using a baghouse filter,
which also separates urea dust from the airstream. Emissions are reduced by at least 95%
while the consumption of ammonia is significantly reduced as well. Global patent awarded.
