In 2022, GreenChem has already more than 7000 contracted systems throughout Europe and this is growing by the day. With all the other products on top of that, many customers rely on GreenChem AdBlue® on a daily basis. Prista Oil Holding is one of the leading Bulgarian companies, operating in more than 40 countries in Central and Eastern Europe, Middle East, Central Asia and North Africa. A. 40% based on the Urea (Prill) fob Balticprice. This index is calculated based on the monthly CRU report Urea prilled bulk Baltic Average–FOB

Prista Oil has its own factories in Bulgaria, Turkey and Uzbekistan where the Company produces lubricants, greases and special fluids. The first clue that your car is running low on AdBlue is that you’ll see a warning light in the instrument cluster. Only very small amounts of AdBlue are used, so a refill is a rare occurrence. A diesel Volkswagen Passat, for instance, takes about 8,000 miles to empty its 13-litre AdBlue tank. And a diesel Peugeot’s tank is refilled when it’s serviced every 12,500 miles. At the end of the first week of the month, the index variation is calculated: this index variation equals the variation between the last known month index divided by the previous one. Flexible: because if demand would suddenly peaks, our production units can easily increase their capacity by simply doubling the shifts. Reliable: because if one production facility breaks down, GreenChem can easily switch to another one to uphold the reliable deliveries of AdBlue ®.AdBlue goes into a tank underneath your car and is injected into the exhaust system to remove NOx from the exhaust gases. You can buy AdBlue in containers and many fuel stations have pumps. How does AdBlue work? The company produces AdBlue ® locally in more than 50 production facilities around Europe and Brazil. This provides us with a very flexible and reliable asset for the production of AdBlue ®.
