“The aim is to recycle construction and demolition (C&D) waste for road construction wherever processing facilities exist. We are working with MoTC to use the processed waste for constructing internal roads. So it will become mandatory soon,” said Mohammed Sulaiman al Harthy, executive vice president - strategic development, Be’ah at Oman Environmental Forum recently.
In an emailed reply to Muscat Daily , he added, “Approximately 2 to 3mn m3 construction and demolition waste is generated every year. Wherever Be’ah’s C&D waste processing facilities exist, this waste is stored within our facilities (landfill and transfer stations) and then processed for aggregates and other fractions. In areas where there are no facilities, they are sent to dumpsites and in many cases illegally dumped in wadis and open areas.
“Be’ah is working with MoTC’s technical team to update the roads and bridges guide in order to incorporate the recycled C&D material in road construction. The revised guide is expected to be published late this year.” A study was conducted to understand the characterisation and chemical composition of the recycled C&D waste to ensure it meets the standards of materials required for construction of roads. It was suggested to utilise the material for building internal roads as they don’t take heavy loads unlike main roads, he said.
“We need to move towards sustainable approaches. We have a target to use 60 per cent of all types of waste by 2020 and 80 per cent by 2030 for recycling, generating energy and for biogas projects. We have several such projects lined up.” Regarding the management of end-of-life tyre waste, he said, “We get 48,000 tonnes of end-of-life tyres a year. Be’ah has awarded temporary contracts to clear the dumping sites and floated a tender on May 8, 2017 for processing end-of-life tyres. We will use the best technology to process them.”
Regarding electronic waste, he said, “We will float a tender soon for investment opportunities for e-waste processing. It is basically the waste generated from discarded televisions, refrigerators and other electronic equipment.
“You have so much waste that needs proper treatment. There are a number of scrap dealers processing this waste. However, the scrap dealers are not handling this waste in the best manner. Be’ah is currently working on setting up a WEEE (Waste Electrical and Electronic Equipment) dismantling facility in Sohar to manage this waste.”
