C. Kniveton Ltd was formed in 1931 originally operating from
Snugborough where it was involved in the production of concrete
product. In 1941 they moved to the Turkeyland site where they
became active in the extraction of stone originally to provide

Colas (IOM) Ltd can trace its roots back to 1962 when the
business was formed as Tony Wilding Ltd. The initial activities of
the company were the sale of drummed bitumen together with minor
contracting work and the supply of ancillary equipment such as
traffic cones, lamps etc. Soon the company had expanded into
surface dressing, macadam contracting, road lining and the
manufacture of road signs.
Shell Ventures had acquired Tony Wilding Ltd in 1974 and
appointed Tony Broom, who had been with surfacing company R.S Clare
Ltd of Liverpool, as the Managing Director and he moved to the
Island to head up the newly acquired company and changed its name
The company went on to acquire Billown and Knivetons in quick
succession, Billown Lime Quarries Ltd in 1977 and C. Kniveton
Ltd in 1978.
Turkeyland Recycling and Waste Management Ltd (TRWM) was founded
in 2005 to provide disposal facilities for the Incinerator Bottom
Ash (IBA) from the recently built Energy from Waste Plant (EfW) and
also to provide recycling and waste disposal facilities for inert
waste. TRWM have now entered into a 10 year agreement with the Isle
of Man Government to now maturate and dispose/store the IBA in
their former coastal quarry at Turkeyland.
On the 1st of January 2015 the four trading companies of Billown
Lime Quarries, Colas IOM, C. Knifeton and Turkeyland Recycling all
became one company, Colas (IOM) Limited.
Our more recent installment to the group is the addition of

another positive step for Colas. Audlyn has an enviable reputation
for producing a quality product and its addition to the Colas Group
reflects our commitment to these ideals.
