Abstract
This application relates to the use of a wire comprising a coating of a bio plastics material as a bookbinding wire or paperclip. The coating is a closed coating offering the wire a good corrosion protection when exposed at normal ambient conditions during use as bookbinding wire or as paperclip and the coating is degradable, biodegradable or compostable once said wire is exposed to an environment suitable for decomposition of said coating. More particularly, the application relates to the use of and to a bookbinding wire and paperclip with a PLA coating. The application further relates to a method for recycling said bookbinding wires and paperclips.
Claims17
Use of a wire comprising a coating of a bio plastics material as a bookbinding wire or paperclip, said coating being a closed coating offering said wire corrosion protection when exposed at normal ambient conditions during use as bookbinding wire or as paperclip and said coating being degradable, biodegradable or compostable coating once said wire is exposed to an environment suitable for decomposition of said coating.
A method for environmentally safe decomposing of bookbinding wires or paperclips comprising a wire covered with a coating of a bio plastic material, said coating being a closed coating offering said wire a corrosion protection during its use as bookbinding wire or as paperclip and said coating being degradable, biodegradable or compostable once said wire is exposed to an environment suitable for decomposition of said coating, said method comprising the steps of
- a) placing said wires or paperclips in an environment suitable for decomposition of the coating in order to form holes in said coating,
- b) allowing said environment to form rust on the steel through said holes, and
- c) waiting until the coating and the steel wire have completely decomposed.
