The short answer is that while waste units are capable of grinding certain types of bones, it is generally not recommended. Waste units are not specifically designed to crush bones, and doing so may cause damage to the appliance. However, they may be able to handle small, soft bones like those found in fish or chicken. But even then, caution should be exercised.
Risks and Issues:
Attempting to grind bones in a waste unit can lead to a number of risks and issues. Firstly, the blades may become dull or damaged when grinding hard materials like bones, reducing the effectiveness of the waste unit. This can result in frequent breakdowns and the need for costly repairs or replacements.
Furthermore, bones can stick to the grinding chamber or components of the waste unit, leading to clogs. This can cause the unit to become jammed or produce unpleasant odors. It may also require disassembly and clean-up, which can be time-consuming and inconvenient.
Alternatives to Grinding Bones:
Instead of using a waste unit to dispose of bones, there are alternative methods that can be employed. One option is to wrap the bones in a plastic bag and dispose of them in the regular trash. Alternatively, bones can be used to make broths or stocks, providing additional flavor to soups or sauces. Bones can also be composted, as long as the compost pile is able to reach high enough temperatures to break them down.
While waste units are generally not designed to crush bones, they may be able to handle small, soft bones to some extent. However, it is important to proceed with caution as attempting to grind bones in a waste unit can damage the appliance and lead to clogs. It is advisable to explore alternative methods for bone disposal, such as wrapping them in plastic bags, using them for stock, or composting them.
