A benevolent army of small robots with the ability to dig up a landfill site and recycle the contents. Each robot would be programmed to collect a particular type of material. They would also be able to make repairs to themselves and on each other with materials found. They would be able to compact their type of material into cube blocks for collection. They would be self sustaining, requiring no input from humans once their task had been set. Naturally they would be extensively programmed with ethical and command subroutines so they would know what to recycle and what not to (ie you wouldnt want them starting on a parked car !!)

Flying jetpacks. Also what really irritates me is that I can't put my contacts and glasses in one case, without the contacts leaking fluids all over my felt lining and causing my glasses to stink.
