At least a third of the food the world grows each year goes to waste, writes John Mandyck, most of it in fields, transport and storage. The result is poor farmers, hungry people, and a massive 3.3 billion tonnes of needless CO2 emissions. It should be a key topic for action at COP21 in Paris - but so far it's not even on the agenda.

The world produces over a billion tonnes a year of dangerously caustic wastes, write Helena Gomes, Mike Rogerson & Will Mayes. They are currently being dumped, although they could be used to sequester a gigatonne of CO2 from the atmosphere - while also yielding minerals essential for key renewable energy technologies.

Hugh Fearnley Whittingstall has a done a great job exposing the scandal of Britain's billions of non-recyclable coffee cups, writes Rhodri Jenkins. But what about the coffee itself?

First we heat up cold water for baths, showers and washing, write Jan Hofman & Laura Piccinini. Then we chuck all that precious heat down the plughole. So how about recycling our waste heat to warm up water on its way to the boiler or hot water tank, cutting bills and emissions? Or on a larger scale, use the sewage from entire communities as a free energy source for heat pumps?

The nuclear industry is forever reinventing itself with one brilliant 'new' idea after another, Amory Lovins wrote in this classic 2009 essay. But whether it's touting the wonders of future SMRs, IFRs or LFTRs, the reality never changes: the reactors they are building right now are over time, over budget and beset by serious, entirely unforeseen technical problems.

Last night's BBC Panorama programme did a good job at lifting the lid on Britain's ongoing nuclear disaster that is Sellafield, writes Ian Fairlie. But it failed to expose the full scandal of the UK's 'reprocessing' of spent fuel into 140 tonnes of plutonium, enough to build 20,000 nuclear bombs - while leaving £100s of billions of maintenance and cleanup costs to future generations.

NASA scientist James Hansen is heading to COP21 in Paris to berate climate campaigners for failing to support 'safe and environmentally-friendly nuclear power', writes Jim Green. But they would gladly support nuclear power if only it really was safe and environment friendly. In fact, it's a very dangerous and hugely expensive distraction from the real climate solutions.

Professor 'Jim' Al'Khalili's 'Inside Sellafield' programme was a tour de force of pro-nuclear propaganda, writes David Lowry - understating the severity of accidents, concealing the role of the UK's nuclear power stations in breeding military plutonium, and giving false reassurance over the unsolved problems of high level nuclear waste.

Don't believe the spurious claims of nuclear shills constantly doing down renewables, writes Mark Diesendorf. Clean, safe renewable energy technologies have the potential to supply 100% of the world's electricity needs - but the first hurdle is to refute the deliberately misleading myths designed to promote the politically powerful but ultimately doomed nuclear industry.

With the sixth anniversary of the Fukushima disaster falling tomorrow, nuclear lobbyists are arguing over solutions to the existential crisis facing nuclear power, writes Jim Green. Some favour a multinational consolidation of large conventional reactor designs, while others back technological innovation and 'small modular reactors'.
