The Instituto Nacional de Seguros says that every month it obtains enough bashed vehicle bumpers to stack them three stories high. These are the damaged auto parts that insurance customers have had replaced, said the company.
So the state firm was faced with the question of what to do with the bumpers.
In conjunction with the Laboratorio Nacional de Materiales y Modelos Estructurales at the Universidad de Costa Rica the insurance firm developed a way to pulverize the composite bumpers for use as an additive for asphalt. The additive makes the asphalt stronger, said the company.
The insurance firm says it is paying for the process.
