Huge Difference between amount of food waste produced and amount recycled:

% of recycled food waste: <1%

From the view of restaurant and Property management company of housing estate: * High Cost of handling food waste
Extra operational costs to hire company for classification of waste, and transportation of waste to waste management company * Difficulties in handling the waste
Storage problem: Bad and stinky smell due to decay of food. Special container and good ventilation system can solve this problem, but those items are self financed which increases the restaurants' operational costs.
Timing for collection: Food waste is only collected by recycling company in specific dates and time, implying that restaurant bear the responsibility to for storage of the food waste. It occupies space, hinder normal business operations and create hygienic problem.
Transportation problem: Special Container and bad odor problem mentioned above, besides, if trucks are rented, it may involve hygienic problem and clean-up fee because of the bad odor remained in the trucks. Also, as water occupies about 80%1 of food waste, heavy weight becomes a booster for transportation cost. * Economies of Scale
The cost for waste management company follows the economies of scale, which greater recycling amount implies a cheaper handling cost per unit. Under the circumstances of insufficient amount of food waste supplied, operation cost increase which leads to lower of profitability.
