In my previous post I looked at two organisations waste management plans, one was Mallow Farm which is run by Mallow Sustainability and the other Zoos Victoria, which has three zoos throughout the Melbourne area. In this post I will be reviewing and assessing the processes followed by Mallow Farm and working out what could be improved.
Mallow Farm runs a small scale organic waste collection and management system for a handful of business in the area west of Brisbane. The waste collected is then composted and used to grow organic vegetables that are then made available for sale to local restaurants and the community. The only source for information on their processes and systems was Facebook, which they update regularly with pictures and information. The farms only current process is that of composting in large piles, which can be quite laborious and slow, but due to the size of their scale this may be the most cost effective method for the time being.

If their scope widens and more business come on board then there are several processes Mallow Farms could take from Zoos Victoria, that will expedite and industrialise their systems to allow for a reduction in time, both man and relative, and an increase in yield, both produce and waste product. For instance, by creating a bio-pod composting dome, like that mentioned in Zoos Victoria prospectus (Zoos Victoria, p28), the speed at which the organic matter breaks down would increase over that of a pile of waste on the ground (current method). Though the zoos prospectus quotes 10 thousand dollars for a handful of domes, much smaller and cheaper ones could be built with waste materials or palettes. Being smaller in size and enclosed less effort and time would be required to turn the waste and for it to breakdown. Another option would be that of a worm farm, Zoos Victoria use these primarily at their Healesville site to process animal waste., this method can break down up to 400kg of organic matter per week ready to be added straight into the gardens. The final method would be to acquire an in-vessel composter like the Hot Rot which quickly and thoroughly composts the organic waste and breaks down any seeds and weeds to prevent the introduction of any unwanted plants or weeds to Mallow Farms garden beds. As the farm is a grass roots organisation with only a handful of people, its scope and outlay needs to remain small. Once it gains momentum then bigger and better things can be added and a system introduced that will allow for things to be done on a larger scale in a faster amount of time.
