What happened

Plastic contamination should be a central concern in efforts to deal with food waste, which campaigners call one of the most overlooked problems of the climate crisis, researchers have said.

Why it matters

This is despite the fact that, as the chef, author and activist Max La Manna puts it, food waste management is “one of the few climate problems where everyone wins”.

Common ground

About one-third of all food produced worldwide is wasted each year, according to UN data.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 1: “even if plastic separation technologies were 99% efficient, diverting food waste from landfill could still increase microplastic pollution in soil by an order of magnitude.”
INSUFFICIENT EVIDENCE
No evidence was found in the search results to support or refute the claim regarding the 99% efficiency of plastic separation and the order of magnitude increase in soil microplastics.

Claim 2: “A new study, published in Nature Food, used life-cycle analysis modelling to compare the impacts – in terms of climate, nutrient pollution and plastic contamination – of different food-waste management scenarios.”
VERIFIED
The existence of the journal 'Nature Food' is verified by Wikipedia, and a web source (Briefly) explicitly describes a Nature Food life-cycle analysis comparing landfilling with recycling across climate, nutrient pollution, and plastic contamination.

Claim 3: “In the US, 40% of food waste goes to landfill”
SINGLE SOURCE
While one source explicitly states '40% of food waste goes to landfill', other sources provide different ranges (30-40% of food is wasted overall) or discuss methane emissions without confirming the specific 40% landfill destination statistic. The evidence is not sufficiently independent to be 'corroborated'.
