Kaucja
by Kaimo
Kaucja adds a bottle deposit system to Forge, with machines, shops, decorative blocks, tools, drinks and food that fit the Create-style base builds on 1.20.1 – 1.20.6.
What it does
Players return empty bottles to a Reverse Vending Machine, which accepts up to nine slots at once and pays a 5% bonus for bulk deposits. The mod centers on that loop, so bottles become a currency that feeds shops and machines.
The content covers a large set of blocks and items. Bottle Bricks come in eight color variants, and bottle-themed decorations include chandeliers, wind chimes, planters, a bottle tree and compost piles. Drinks and food carry hunger and saturation values, and the tools and weapons include a bottle cap tool set and bottle-firing turrets.
Kaucja runs on client and server, so the server and every player need it. It is published for Forge only, across six game versions 1.20.1 – 1.20.6, and the code is under All rights reserved, so it is not freely licensed. The latest file, 10.0.0, was released on 2026-09-05.
