| By 1 July 2030 all councils in New South Wales – the country’s most populous state – will be required to provide household Fogo collection. More than 40 councils across Sydney and the regions have already done so. The aim is to halve the amount of organics going to landfill by 2030. | By 1 July 2030 all councils in New South Wales – the country’s most populous state – will be required to provide household Fogo collection.

| It currently processes mostly red bin waste and a small amount of Fogo (30,000 tonnes a year) – but over the next few years the plan is that Fogo will become the main, and then the sole, waste treated at the plant. That would mean taking in 300,000 tonnes of Fogo a year. | It currently processes mostly red bin waste and a small amount of Fogo (30,000 tonnes a year) – but over the next few years the plan is that Fogo will become the main, and then the sole, waste treated at the plant.

| The Fogo travels through a machine called the Terminator that splits open bin bags, then past four men in a “sorting cabin” who pull “incompatibles” off the line and into a pile destined for landfill – the tree stump will come off the conveyor belt here, Turner says. | The Fogo travels through a machine called the Terminator that splits open bin bags, then past four men in a “sorting cabin” who pull “incompatibles” off the line and into a pile destined for landfill – the tree stump will come off the conveyor belt here, Turner says. |
| The rest moves through different machines, including a shredder, various screens to separate larger pieces, and a wind system, which separates waste by weight. The “alchemy section” uses magnets to remove any metal, before the waste makes its way to a giant compost hall, 50 metres wide and 209 metres long. | The rest moves through different machines, including a shredder, various screens to separate larger pieces, and a wind system, which separates waste by weight.

| There, the waste will sit and cook for two weeks, kept at a temperature of 55-60C and regularly sprayed with water to keep it at 50% moisture. It will be turned by giant augers, until the result is a rich, brown compost, that undergoes one more round of sorting (into a machine called the “refinery” that screens out objects bigger than 10mm) before it becomes compost for agriculture. | |
| Currently Cleanaway compost is shipped to farms in Oberon and Molong, 180km and 290km west of Sydney respectively, though Turner says the cost of transport is one of the big sticking points in the process. | Currently Cleanaway compost is shipped to farms in Oberon and Molong, 180km and 290km west of Sydney respectively, though Turner says the cost of transport is one of the big sticking points in the process. |
| “Apart from getting a significant yield increase, we’re also getting organic material back in the ground,” he says. “Ideally we’d get to farmland that’s somewhat denuded and then … we’ll also start the process of rebuilding the stability and the organic base of the soil, which would be very idealistic, but it would be a pretty fantastic story.” | “Apart from getting a significant yield increase, we’re also getting organic material back in the ground,” he says. “Ideally we’d get to farmland that’s somewhat denuded and then … we’ll also start the process of rebuilding the stability and the organic base of the soil, which would be very idealistic, but it would be a pretty fantastic story.” |

| Because fruit and vegetable stickers are often smaller than the fine sieve used on the compost (10mm) they make it through the refinery. Because they are soft plastics, and the compost these facilities produce is allowed to contain only 0.05% of soft plastics to be compliant, the stickers add up. | Because fruit and vegetable stickers are often smaller than the fine sieve used on the compost (10mm) they make it through the refinery.

| Turner is also exercised by the green bags used for food waste, which are required by many councils. Some councils supply bags, which he says are fine. But he says that some of the ones sold at the supermarket are not compostable and will break down into microplastics that are then ploughed into the soil along with the compost. | Turner is also exercised by the green bags used for food waste, which are required by many councils.

| The dramatic collapse of RedCycle revealed that many Australians had been sorting and returning soft plastics only to discover the recycling pathway had broken down and they were instead being warehoused. Understandably that left many sceptical about recycling, as did multiple investigations into where recycling waste is shipped and what becomes of it. | The dramatic collapse of RedCycle revealed that many Australians had been sorting and returning soft plastics only to discover the recycling pathway had broken down and they were instead being warehoused.
