Fodd bynnag, mae’n bwysig nad cyfrifoldeb deiliaid cartrefi yn unig yw’r baich o leihau gwastraff bwyd a phecynnu. Ar y cyd, mae’r Sectorau Gweithgynhyrchu, Gweini a Manwerthu Bwyd yn gyfrifol am 40 y cant o’n gwastraff diwydiannol a masnachol. At hynny, gwastraff bwyd sydd â’r ôl-troed ecolegol mwyaf; ac mae’n gyfrifol am 30 y cant o ôl-troed ecolegol ein gwastraff diwydiannol a masnachol yn gyffredinol. Mae’r Sectorau Gweithgynhyrchu, Gweini a Manwerthu Bwyd, yn cynnig lleihau gwastraff o  1.2 y cant bob blwyddyn. Mae’n canolbwyntio hefyd ar y deunyddiau sy’n cael yr effaith fwyaf ar yr amgylchedd, neu’r rhai mwyaf hawdd eu hailgylchu; sef bwyd, papur a chardfwrdd, plastig, gwydr, metel a phren. Y nod yw ailgylchu gwastraff sych fel gwydr, papur a chardfwrdd a phlastigau, a thrin gwastraff bwyd drwy broses treulio anaerobig.
It is important though, that the burden of reducing food and packaging waste does not rest solely with householders. The food manufacture, service and retail sectors together generate 40 per cent of our industrial and commercial waste, while food waste has the largest ecological footprint; accounting for 30 per cent of the total ecological footprint for industrial and commercial waste. The Food Manufacture, Service and Retail Sector plan proposes a reduction of waste of 1.2 per cent every year. It also focuses on those materials which have the biggest environmental impact or are the easiest to recycle; food, paper & card, plastic, glass, metal and wood. The aim is to recycle dry wastes such as glass, paper and card and plastics, and for food waste to be treated by anaerobic digestion.
