    Turn recycling focus on scrap metal

    Rokiah Mahmud

    In the past five years, iron and steel waste has made up around nine per cent or 45 kilo-tonnes per annum (kTpa) of waste generated in Brunei Darussalam. Additionally, there is a potential volume of decommissioning and restoration (D&R) activities in the local scrap metal market.

    “This is evident as there is an established ecosystem of iron and steel recyclers in the country that has been directly exporting around 90 per cent (40kTpa) of current steel waste being generated,” said Brunei Shell Petroleum Company Sdn Bhd (BSP) Manager Hajah Rosita binti Haji Hassan in her presentation at the Brunei Mid-Year Conference and Exhibition (MYCE) 2021 yesterday. “On this note, in the next 30 years, the accumulative waste generated from iron and steel is expected to increase as waste from BSP D&R activities could contribute about 120,000 tonnes (16,000 tonnes in the next 10 years).”

    She said, “At the same time, there are also unaddressed segments of ecosystem like white goods and end-of-life vehicles due to limited local infrastructures.

    “Over the past five years, Brunei has imported an average of 125,000 tonnes of steel annually. Nearly half of the total amount (around 58,000 tonnes) is in the form of less complex bar and rod products which are mainly used in the construction sector.

    She added, “Between 2015 and 2019, Brunei imported an average of 125 kTpa of steel in which 57 kTpa (47 per cent) is used for bars and rods, which have seen a consistent demand over the years driven in a large part by the construction industry.

    “Among the key customers in the construction industry are TSL, LSL and Swee. Meanwhile consumers of steel in other industries include oil and gas, as well as manufacturing, such as BSP, HLDS and Hengyi which utilise more hot-rolled coils, angles, shapes and sections.

    “Over the past 10 years, Brunei has generated around 37,000 tonnes of scrap steel annually. Between 2010 and 2019, Brunei’s scrap waste had been growing at 4.3 per cent. In addition, there are 18,000 tonnes of currently untapped steel in the form of white goods and vehicle imports.

    “Fourteen kTpa of steel can be recovered from 18 kTpa of cars imported annually with typical vehicles lifespans of 15 to 20 years. At the same time, there are already inactive vehicles in Brunei, totalling 170,000 kTpa (210,000 tonnes of steel).

    “Out of 450,850 registered vehicles, only 278, 033 are active vehicles. Furthermore, there is 4kTpa of steel that can be recovered from white goods, which are currently sent to landfills.”

    Meanwhile, D&R Petroleum Authority of Brunei Darussalam Project Engineer Alirupeman bin Haji Perudin’s presentation on ‘Repurposing & Restoration’ discussed the spin-off through a supply chain covering repurposing and its contribution to a circular economy.

    “The scope of decommissioning also includes post-removal waste management and site restoration,” he said.

    Alirupeman cited the Seria Energy Lab Park and Solar PV Plant as examples of site restoration, where both land areas were restored from well sites, facilities and residential housing.
