Plastics are generally made from fossil gas or petroleum; thus, the production of plastics creates further fugitive emissions of methane when the fossil gas or petroleum is produced. Additionally, much of the energy used in plastic production is not sustainable energy ; for example, high temperature from burning fossil gas.
Oat milk, like most plant-based milks, is made of disintegrated and hydrolyzed plant materials, resulting in non-uniform particle sizes in comparison to bovine milk.
