We as a community believe that every thing has its own value, and that is why we are encouraged to develop sustainable resource recovery. However, some unreasonable treatments of organic waste have damaged our environment. When organic matter decomposes in landfill it generates methane, a potent greenhouse gas. But if the organics are used in the right way such as replenishing our soils and gardens via compost and mulch, this will contribute positively to our lives. Some organic waste management organizations currently help us live sustainably.
In the document National Waste Reporting in 2013, 3/4 of organic wastes were recycled and 1/6 were used in energy recovery (National waste reporting 2013). The chart below reflected total waste generation through material categories and resource recovery management that was produced by the Australian Government.
(National waste reporting 2013)
Besides this, under the guidance and management of the Australian Government, New South Wales and Victoria achieved resource recovery rates above the national average in 2010-2011(National waste reporting 2013).
Not only do world governments have a responsibility to manage their national organic waste systems, there are also some organizations within the countries that apply real action to manage their own waste systems. Zoos Victoria is working to achieve zero waste to landfill across their three zoos by 2019 through separating all recyclable materials, creating compost, and as a result, renewable energy. From worm farming to in-vessel composting, they have done a wonderful management plan at this moment. There are four main methods they are working on to manage organic waste. First, they have public place recycling, which is set up with a bin system; waste, green waste recycling and comingled recycling. Secondly, worm farming is used to deal with animal waste. Around 400 kilograms of organic waste that is produced by their animal husbandry and catering is returned back to make soil conditioners and fertilisers (Zoos Victoria). Likewise, some exhibits are designed with recycled materials from previous collections. In addition, the ‘Zoo Gro Compost’ produces high quality soil that can kill off any weeds and seeds, and will help improve water and nutrient retention (Zoos Victoria).
These organizations manage their organic waste not only locally, but also internationally. Bir Hospital is a model of responsible recycling of hospital waste, and has influenced not only other hospitals in Nepal but around the world. Before their current systems, approximately 365 tons of medical waste was discarded into the municipal dumps per day; which led to 323 kg of infectious waste going into the public garbage system and being distributed into the environment, which was infecting patients and staff (Bhrikuti 2011). Therefore, they started to manage medical waste. Methane produced by organic waste in the underground methane tank is used for cooking. Non biodegradable waste is recycled and sold to a vendor or used to make handicrafts(Bhrikuti 2011). Due to this effective manage system, the environment is becoming better and patients are recovering faster.
In order to create a green future, every one needs focus more attention on managing their own organic waste and applying this into real action.
