From this month, the agency’s Blue Horizons magazine is being packaged in a 100% compostable polybag wrapper made from material derived from potato starch.

The wrapping can be disposed of along with kitchen food waste, placed on compost heaps or in garden waste bins where it will decompose.

Blue Horizons will also be created using paper from sustainably managed forests, where trees are replanted as they are felled.

"While the production cost for the new wrapping is higher than the traditional plastic bags, ROL Cruise is committed to taking steps to reduce its single-use plastic usage," the agency said in a statement.

At its Colchester head office ROL has also committed to a range of recycling procedures.

This includes collecting, shredding and recycling all paper waste; recycling printer toner cartridges and ensuring all cardboard and general waste is collected by a collection management firm with its own sorting and recycling facility.

All computer equipment which can no longer be used is also being recycled.
