Never
A food waste disposer, also known as a garbage disposal, grinds scraps right in the sink: here is what happens with walnut, hazelnut, almond, pistachio shells.
No, not with any model.
Hard and woody: they go in the food waste bin.
suitablecrossed out: not suitable
Cold water, a little at a time, mixed loads.Food scraps only. Never fats or oils, never anything that isn't food.
Walnut, hazelnut, almond, pistachio shells are too solid for the chamber: they bounce around and come out whole. The grind would never be fine enough to flow: it would stop at the first bend of the drain. Walnuts, hazelnuts and almonds have woody shells, pistachios very hard ones: they do not break down into fine particles. Hard and woody: they go in the food waste bin. The place for this is the organic waste bin, not the sink.
