Material Waste

Material waste from riveting arises in several forms. Direct scrap includes defective rivets, trimmed tails from solid rivets, and shavings from hole preparation (drilling or punching). In aerospace applications, where holes must be precision-drilled before riveting, metal chips are generated from both the workpiece and the fastener. Even in self-piercing riveting (SPR) systems that eliminate pre-drilling, the rivet itself becomes part of the waste stream if the joint fails quality inspection. Rejected assemblies can result in complete scrapping of expensive components, multiplying waste significantly.

Packaging waste frem rivet supple - cardboard boxes, plastic trays, and protectiva coatings - adds to te landfill burden.
