Sealed countertop or under-sink appliance that grinds and either dehydrates or aerobically digests food waste, including cooked food, meat, and dairy that an open compost pile can't handle without attracting pests and odor. Dehydration-type units produce a dried, volume-reduced material needing further composting; sealed aerobic digester types can fully break it down. Odor-contained, fast (hours, not weeks), and low-effort, at the cost of continuous power draw, a proprietary sealed mechanism, and an ongoing filter/consumable cost.
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
