In some examples, one or more metal-containing catalysts and one or more waxes can be mixed or otherwise combined to produce an encapsulated catalyst composition. The wax can be at least partially coated on the metal-containing catalyst. A mixture of water and the wax can be agitated or otherwise mixed, and the metal-containing catalyst can be added to or otherwise combined with the water and wax mixture to produce a wax emulsified catalyst. A plurality of lignocellulose substrates, one or more oxidants, and the encapsulated catalyst composition can be mixed or otherwise combined to produce a lignocellulose binder mixture. The lignocellulose binder mixture can be heated to produce a composite product.
