TNT GROUP designs removable recycled-zamak collar for Bottega Veneta refills

TNT GROUP has developed a removable collar in 75%-recycled zamak for the ten refillable bottles in Bottega Veneta's Alta fragrance collection, pairing a polypropylene insert with a gold-tone finish designed to withstand fragrance exposure. The design targets a common conflict in refillable luxury packaging: collars must stay mechanically stable through repeated use yet separate cleanly for recycling at end of life.

Why this mattersThe design shows how metal-component makers can raise recycled content on visible, load-bearing parts of refillable luxury packaging without compromising durability.

• TNT GROUP moulded the collar from 75%-recycled zamak with a polypropylene insert
• The collar is used across ten refillable bottles in Bottega Veneta's Alta fragrance collection
• The design must allow removal for material separation at end of life while withstanding repeated refill use
• A gold-tone metallic finish and lacquer were developed to resist fragrance exposure
• TNT GROUP was founded in 2013 and operates from Hong Kong, New York and Paris
