Colex Holdings Limited ("Colex"), a 40-year veteran of waste management in Singapore that has pioneered many innovative value-added services which include the fully mechanised waste disposal vehicles and portable waste compactors used in the industry today, was listed on the SESDAQ (now known as Catalist of Singapore Exchange Securities Trading Limited) in April 1999.

Colex attained its ISO 9001:2000 Quality Management System certification in February 2003, which was converted to ISO 9001:2008 in March 2010. The ISO 14001:2004 Environmental Management System certification was attained in May 2010.

Colex specialises in waste disposal for a wide portfolio of clients including commercial offices, shopping complexes, food courts, cineplexes, residential buildings and warehouses.

Colex's unwavering focus on quality and service has resulted in it being awarded by the National Environment Agency ("NEA"), the 5-year Bedok sector municipal waste collection contract in 1999. This was followed by the 7-year Jurong sector municipal waste collection contract which commenced on 1 April 2006.

On 23 November 2012, Colex was awarded a second term 7-year contract for the Jurong sector by the NEA which commenced on 1 April 2013.

In 1999, Colex acquired Integrated Property Management Pte Ltd ("IPM") and with this acquisition, Colex's activities were extended to include contract cleaning of commercial, industrial and residential buildings.

On 1 April 2013, the waste disposal segment has been reorganised under Colex Environmental Pte Ltd ("CEPL"), a wholly owned subsidiary of Colex. CEPL's principal activity is to provide waste management and recycling services to the industrial and commercial segments and disposal and recycling of public waste licensed by NEA. Colex has become the investment and holding company.

Providing customers with quality and value-added services remains Colex's key guiding principle and strategy in maintaining competitiveness. Where new market opportunities arise, the Group will forge strategic alliances and business relationships with other members of the industry and NEA for greater growth.
