I'm very interested in learning more about plastic-alternatives, Ono.
Have you, from firsthand experience, frequented any specific online vendors that sell carriers/containers made from those types of food-waste you'd mentioned? Because, especially when you live in a rural town like mine, access to such packaging is rarely local.
Also, what are the best raw materials to use (in the manufacturing process) that create biodegradable and "compostable" bags/carriers/containers for either single-use or re-use? In order to create better consumer demand...we have to know what exactly we're demanding.
