Vast majority of Hong Kong’s food waste is disposed at landfills along with other municipal solid waste. Approximately 10,000 tonnes of municipal solid waste are disposed on a daily basis and food waste are accounted for around 30% of all MSW.
This current solution is simply unsustainable. Not only does it occupy more of Hong Kong’s limited landfills, organic substances in food waste are wasted and food waste at landfill will potentially cause further pollution.
As it is unrealistic to focus all efforts on reducing food waste from the source, more resources should be dedicated to a more sophisticated solution to food waste processing.
Hong Kong Environment Protection Dept (EPD) has demonstrated the food waste disposal since 2008 to manage 500 tons annually collecting from food waste to 50 tons composting residues. That facility has completed the mission of demonstration for over 10 years and shut down in 2018 October. The composting residue could be modified to be Fertilizer or improving soil to use in planting, gardening and cord.
Although the problem of food waste is aggravating in Hong Kong, it’s been proven that the private sector simply can’t provide a profitable solution to food waste without some sorts of government intervention.
Currently O-Park 1 is disposing approximate 200 tons food waste per day that mostly collect from recycling private cleaning company. However, it is just a small portion from the daily food waste 3200 tons in HK.
: zero waste, zero pollution and a complete ecosystem
Improve the efficiency of the nutritional value of organic fertilizers
We introduce American biochemical technology, adding the live lactic acid bacteria method and the amine creatine method to make the nutrients of the original nutrient-rich organic fertilizers more powerful and controlled.
Promote the use of local organic fertilizers in local agriculture
By providing our organic fertilizers to the local farms we work with, we in turn receive pre-appointed seasonal vegetables and fruits. When the agricultural products are produced, we will also provide them to customers purchasing our service so that local crops can be enjoyed locally. When local users adopt local agricultural products, the second round of ecological cycle will be carried out again, and so on. The local ecological cycle will continue to be carried out, creating an integrated and sustainable system, our mechanism for the local food waste treatment in Hong Kong.
