New composters for food waste management in Greater Vancouver Area

hungry city

Recently this Autumn, there are 2 new composters for food waste have been launching in Metro Vancouver, British Columbia. They arrive at the right time to support the Zero Waste program as Metro Vancouver will be banning on organic materials (including food scraps and compostable organics) in the garbage disposal starting in January 2015. Burnaby Red Wigglers has participated the discussion on the launching of the Hungry Bin across North America and of the Citypod at the Student Union, University of British Columbia, Vancouver Campus.

The first composter is Hungry Bin, a simple and easy composter method with the similar size as the green or black garbage plastic container that can be found in the neighborhood. Hungry Bin is designed and imported from New Zealand and has been told can process 2 kg of food waste per day. According to their instruction, in normal operation, the finish product compost will need to be harvested from the bin once every 2-6 months.

The second is Citypod, a well control composter with sophisticated technology, compact dimensions (447X109X125cm) combination of thermophilic, rotary drum and in vessel aerated systems. Citypod is made in Montreal and has been told can process 100 kg of food waste per day. According to their instruction, the finish product compost can be harvested after 2-3 months for the 10% of the volume of the daily feed, so it will be 10 kg of compost per day.

It has been discussed between the business owners of both companies with Burnaby Red Wigglers that both composter systems Hungry Bin and Citypod need compost worms or red wigglers to speed-up and stabilize the decomposition process of the food waste in order to produce a good compost or vermicompost.

As there is too much food waste around us, both composters may complement each other to support the Zero Waste program, sustainability, organic farming and bioremediation for a better local environment; furthermore, the 2 new systems need to be evaluated. The evaluation can be for the efficiency (e.g. time, energy, labour), homogeneity of the process (e.g. repeatable, on time), aesthetic (e.g. odour), costs and benefits, and the quality of the finish product compost.

Please contact www.burnabyredwigglers.com for the optimization of the worm composting or vermicomposting and to get the compost worms or red wigglers. Alternative technologies for food waste management related to vermiculture are also available such as automated continuous-flow vermicomposter and anaerobic digester. Bintoro Gunadi
