Disposable plates and bowls can be made from materials like paper, plastic, plant fibres, sugarcane, bamboo or wood. Paper plates and bowls use virgin or recycled paper pulp. They may have a thin waterproof coating because raw paper absorbs liquids and grease. Plates and bowls made from plant fibres like bagasse or bamboo are rigid, leak-resistant and can be placed in a compost bin. Plastic plates and bowls are made from polymers like polystyrene or polypropylene.

Not all disposable plates and bowls are safe to use in a microwave. Check the packaging or the bottom of the dish to see if there is a “microwave-safe” label or symbol. Disposable plates and bowls with plastic or wax linings can melt or warp when heated in a microwave. Plain paper plates and bowls are safe for short-term reheating. Sugarcane and bamboo plates and bowls are also microwave-safe for short intervals. Avoid plates and bowls with printed designs because the ink or dye can transfer when heated. Do not microwave plastic or foam plates and bowls because they can also melt and warp from the heat.

Disposable plates and bowls can hold hot foods and liquids. Look for options that are specifically labelled for high temperatures. Bagasse and bamboo plates and bowls are naturally heat-resistant, sturdy and less likely to get soggy quickly. They can handle hot and greasy food. Paper plates and bowls with plastic or wax linings can hold hot foods without leaking. Try to avoid thinner paper plates because heat and moisture can weaken untreated paper fibres.

How you dispose of disposable plates and bowls depends on the materials they’re made from. Uncoated paper plates and bowls without heavy food stains can go in the green bin or recycling bin depending on local municipal rules. Plastic or wax-coated plates and bowls cannot be composted and must be thrown out in a garbage bin. Rigid plastic plates and bowls can be recycled if they’re completely emptied and rinsed of food residue. Styrofoam plates and bowls belong in the garbage. Bagasse or plant-based bowls can go into a compost bin or green bin if your municipality processes them. Biodegradable plastics are usually not accepted in green bins and must go in the garbage. Be sure to check your local guidelines if you’re not sure what’s allowed.
