I’ve been a refuse collector for 12 years these were the days when it was so much better I would of loved to of worked on a revopak shredding up bulky waste and bags .In France in 1968 Semat invented the superpac and in 1971 U.K. S&D invented the revopak under license from Semat in France revopaks started phasing out in the mid to late 1980s .
