What estimated 'saving'? Rubbish. Reduction, reuse, recycling and composting is ALWAYS cheaper for local authorities, than incineration. Incin contracts ALWAYS stipulate that recyclable and compostable materials ie 'calorific' and 'organic' are 'procured' for destruction, instead of the cheaper 3Rs (& composting) eg Derby/Derbyshire, Derby city council even admitted to DEFRA that recycling was cheaper than incineration! Councils now paying the cost of getting out of the high-carbon, wasteful, PWC/Deloitte et al contracts.

It will cost the earth and future generations, not to collect it and turn it into compost. Burning it, as biomethane etc, is high-carbon & the residual left over from bio-m etc is not as good as compost made from unburned foodwaste/organics etc. Derby/Derbyshire shot themselves in the foot by signing a contract to destroy such 'waste' resources, ending up possibly having to pay millions, because of a financially insecure contract & company; recycling figures plummeted & costs increased - https://derbyfoe.com/reduce-reuse-recycle-compost-cheaper-than-incineration/
Comment on: AD 'can cut UK greenhouse gas emissions by 5%'
Its still a burning process, causing CO2 and misery to nearby local communities. In Derbyshire, there is a campaign against AD from a massive proposed piggery, with resulting air pollution, bisphenol contamination etc. especially if mixed with household/other waste. Compost made from foodwaste etc instead is of a much better quality, than the leftovers from AD

Comment on: Large-scale EfW on the cards for Lancashire
Derby and Derbyshire councils made the same mistake and are bitterly regretting the Derbyshire high-carbon plastics/biomass/biowaste/resources incinerator and accompanying contract.
Mass balance reveals more energy wasted, than the tiny amount created. They are purely for disposal and the contracts set up, destroy reduction, reuse, recycling and composting, as they rely on increasing tonnages of 'calorific' and 'organic' materials, for destruction. That's not residual waste, so they 'procure' the recyclables instead, destroying 3Rs.
Should be renamed 'energy-to-waste'
Mass balance of such high-carbon 'energy-to-waste' plants reveals more energy wasted, than the tiny amount created. Reduction, resue, recycling and composting also end, wherever they are built, as they need resources, purely to destroy eg Renewi in Derbyshire
