“Greening the Desert” was the vision of the founding President of the United Arab Emirates, His Highness the late Sheikh Zayed bin Sultan Al Nahyan. Today this vision is a reality because Abu Dhabi has planted 14 million trees in 250,000 hectares of forest, which are irrigated from 5,651 wells by a network of 55,000 km of irrigation pipes. These forests provide an effective screen against sand storms and dune invasion of roads, agricultural holdings and populated areas. They also provide shelter and fodder for the large numbers of wild animal species and help cool the environment especially in the hot summer months. One of the companies managing these forested areas is Barari Forest Management who used to purchase their pipes locally but on many occasions these laterals failed prematurely, sometimes after being in operation for less than a year. Due to the vast spread of these forests as well as their remote location and inaccessibility, maintenance cannot be easily carried out when there was a failure. Shutting down the irrigation networks temporarily was not a viable option because the plants need to be constantly watered in the extremely arid environment. With support from Borouge, Barari have been able to set up their own production of high quality irrigation pipes using pre-compounded material. Thanks to a joint study they have also been able to fulfil their mandate to minimize waste and maximizing recycling efforts by using their recycled material without significantly reducing product performance. This paper describes the detailed programme where controlled amounts of recycled material are added during the pipe production process and the results of evaluation to determine its durability in the field.
