Germany is the sorting champion: yellow bin (packaging), blue (paper), brown (bio), black (residual), glass by color. The bio bin becomes compost and biogas. Home compost is free fertilizer: kitchen scraps (no meat/dairy) + garden cuttings + cardboard = black gold in 6–12 months.

• ●Into compost: peels, coffee grounds, eggshells, leaves
• ●Not into compost: meat, dairy, diseased plants — smell and rats
• ●Pfand is the bottle deposit: €0.08–0.25 — return and collect
