The construction firm is giving reusable 500ml aluminium drinks bottles to all of its 119 staff, as well as removing all plastic cups next to water coolers.
It will also be calling on subcontractors at its sites to signed up to the plastic waste campaign.
Ian Plowman, operations director, said: “Caddick Construction has always been committed to our sustainability targets, and we’re excited to take a big step toward eliminating plastic wastage.
“The construction industry made huge strides in recent years in tackling other forms of environmental damage, and with plastic waste in the public eye following Blue Planet II, it is a logical next frontier.”
This move comes as the government is weighing up several initiatives to cut use of single-use plastics as public awareness of the issue has increased. In January, the Environmental Audit Committee found that the UK throws away 2.5 billion plastic cups every year.
The country also uses over 3 billion plastic bottles a year, with 40% of those ending up in landfill.
