The problem?
Simple ignorance. Unfamiliarity. Fear. Laziness.  Aversion to working with 'wastes'.  Information assymetry. Myths, disinformation, risk aversion, a Zeitgeist of apathy, disbelief, defeatism, lack of trust, lack of experimentation, systemic patron-client discouragement, bad public policy, lack of incentives, withholding of key information motivated by a desire for profit and personal gain. All psychological, none technological or material.
