Métier Mixed Concrete
Métier strives to responsibly steward its working environment and mitigate the negative environmental impact of operations.
Métier uses the cement manufactured by, among others, SepCem to manufacture mixed concrete, which harnesses downstream value for the group. The subsidiary sources its raw materials from different suppliers and secures strategic inputs from sustainable producers. Métier regularly engages independent experts on how to develop effective environmental programmes that comply with the regulatory framework and that mitigate its negative environmental impact. The subsidiary also regularly consults with the relevant authorities on environmental management matters, which include bunded fuel areas; plant storm water run-off and storage; water usage and recycling and dust emissions. All concrete returns are dried and disposed through quarry operators for crushing or to approved contractors for use in construction activities such as road layer works and fills.
Dust emissions management
Métier proactively monitors dust emissions and recycles wash water sediment, which are the only two material outputs that impact the environment. The bulk of the dust comes from natural sand and natural crushed stone. The dust emissions have been within the regulatory limit of 1 200 mg per m² per day achieved by using mist sprayers, sprinklers and dust curtains to control the emissions. Furthermore, the silos have dust filters at the top which limit emissions during the re-filling process.
Métier recycled approximately 37 million litres during the 2018 financial year that was used in washing out the concrete drums and cleaning of the trucks and plants.
SepCem continually minimises its operations’ environmental impacts through decisions that serve the interest of the business and society.
SepCem complies with all legislation and has the necessary environmental licences and permits. Its environmental management programme identifies and manages socio-environmental impacts, risks and liabilities during the environmental impact assessments. The associate’s environmental management strategy minimises water consumption, improves energy efficiency and mitigates against point and non-point source emissions. The Aganang and Delmas plants were designed to have limited environmental impact, and SepCem further reduces its impacts with mitigatory measures for any dust and/or noise pollution.
Limestone is the principal raw material for cement, and it is used to manufacture clinker at SepCem’s technologically advanced plants. The associate’s responsible mining practices minimise its environmental impacts and do not disrupt neighbouring communities. SepCem regularly engages different authorities to ensure compliance to licence conditions and to better steward the limited water resources whilst managing and monitoring several parameters including water balance. This, together with the closed-circuit water systems at the plants, maximises recycling and minimises discharge into the environment. SepCem is committed to a high standard of environmental performance and to sound principles of sustainable development. The associate’s management understand that robust environmental management systems and a proactive approach to addressing the challenges and harnessing opportunities of climate change, are fundamental to operational success.
