Alumex, Sri Lanka’s leading fully integrated aluminium profiles manufacturer and member of the
Hayleys Group, joined the Aluminium Stewardship Initiative (ASI) as the new member of the
Production and Transformation Division.
ASI is a not-for-profit standard-setting and certification organization, bringing together producers,
users and stakeholders in the value chain with a commitment to maximising the contribution of
aluminium to a sustainable society. As the first Sri Lankan manufacturer to have committed to the
standards, Alumex will work with members to foster responsible production, sourcing and
“As Sri Lanka’s largest manufacturer and exporter of aluminium, we are well aware of the
importance of integrating sustainability in our business and manufacturing process. ASI is backed by
an assurance program which will enable us to strengthen our commitment to transparency and
credibility. We believe this is fundamentally important for our people and customers in Sri Lanka and
our rapidly expanding export markets,” Alumex Managing Director Pramuk Dediwela said.
The ASI certification programme provides assurance for two voluntary standards: the ASI
Performance Standard and the ASI Chain of Custody Standard. While the former defines
environmental, social and governance principles and criteria addressing sustainability, the latter sets
out the requirements for the maintenance of materials.
Notably, Alumex strengthened its commitment to sustainability by setting up an aluminium waste-
collection points in selected areas. The manufacturer also upgraded its recycling facility with state-of-
the-art machinery to significantly reduce its environmental footprint. Alumex’s latest facility in
Sapugaskanda is capable of recycling more than 1200 metric tons of Aluminium scrap per month
which can be upgraded by another 1200 metric tons, with an annual recycling capacity of 28,800
metric tons. With the commencement of its commercial operation by July 2022, this would become
the largest Aluminium recycling plant in Sri Lanka with the state-of-the-art technology.
Most recently, Alumex was recognised for its strong commitment to transparency and governance
at the Asia Integrated Reporting Awards. The manufacturer was honoured with the Bronze in
Integrated Report (SME) category for its disclosures on value creation to stakeholders.
Since its inception in 2012, ASI has become the recognised authority in Aluminium stewardship,
enabling the industry to demonstrate responsibility and provide independent, credible, and verifiable
information regarding practices and improvements in ethical, social and environmental performance.
ASI currently has 232 members globally and has issued 128 certifications against the ASI
performance standard and 51 against the CoC standard. ASI members are operating in 47 countries
throughout the world.
