Lids4Kids is a charity registered with the Australian Charities and Not-for-profits Commission (ACNC) that has lids manufactured into benches, tables, splashbacks and roof tiles. Its site now states it has no drop-off or collection points; the replacement is the paid Zero Waste Warrior service (Swap and Go in the Australian Capital Territory (ACT), mail-in bags via Australia Post elsewhere), plus washed, colour-sorted lids accepted at its Canberra hub.
Honest caveat: paying to post lids is a lot of effort and freight for a few grams of polypropylene; container deposit schemes in most states now accept lids left on bottles, which is free.
