Post D- Alternative System

Taronga Zoo/ SITA have began an effective organics waste foundation partnership with the offsite sorting and production levels. But what if it was to be done onsite?

The process of taking the organics which is transported in trucks further add to fossil fuels and green house gasses in the environment. This could be reduced by having an organics management onsite. The use of the Victorian Zoo organics waste management is onsite creates an easy access for the composted matter usage around the zoo and has a more controlled environment. As the employees get to see and understand the process.

While Taronga is well established in the organics waste management area, it can be improved. Using a machine to create organic matter into biogas and compost, as spoke about in Paul Sewells TED Talk,  in a zoo would be more beneficial then having an off site plant. Having this machine it would create biogas and be reused in the zoo for electricity and potentially using the bio gas to run the trucks and machinery at the zoo. While also create compost that can be used for fertiliser.

The effectiveness of organic waste management is outstanding and has improved significantly in the past few years, but if the management would also consider the production in organic waste management and create a better solution thats more economical, that would be incredible.


Taronga zoo, powered by bio gas which is generated onsite by the organic matter created from the visitors, animals, employees and production.

Biogas fuelling the machines onsite and the electricity on site. Organic matter used as soil for the gardens and enclosures. Example: Below is a graph of a bio gas digester based on a farm. A zoo can be seen as a farm. Animals live there and are looked after, they also create wastage which can we turned into a gas to fuel the zoo.

If Taronga zoo implemented this design which is underground, having no space taken up onsite the proposal could be efficient and work well.

Having a system that is under ground, not effecting and taking up space in the zoo is ideal. It eliminates the factor of taking up more space. As the zoo is in the city, it doesn’t have  a lot of room. So why not have it underground?

Evidence of an effective use of bio gas is at Ruth Roby Glancy Animal Health Complex where they have saved thousands of dollars yearly due to bio gas. If this is only on one section of the zoo, a whole zoo could benefit even at a greater level. Not only will machines be fuelled by bio gas and save the zoo money, it saves the environment green house gases, which is also preventing the animals in close vicinity of breathing in the chemicals from machinery.w

One thought on “Post D- Alternative System”

  1. I like the ted talk you linked, it’s a good summary of the organic waste problem.

    On-site management and solutions are a good idea since they probably save time and space as well.
