Moreland Council intends rolling out synthetic turf when evidence points to it being a highly problematic environmental and climate issue and at a substantially greater lifecycle cost even when factoring in a higher usage ratio.
So it seems the ratepayers of Moreland are going to be hit with expensive replacement costs of synthetic fields every 7-10 years, an increase in urban heat island which will result in health impacts to residents especially during extreme heat events which are becoming more common, an increase in microplastics pollution to local waterways and Port Philip Bay, 274 tonnes of landfill every 7-10 years, reduced abundance of birdlife, and extra greenhouse gas emissions (lifecycle emissions range from 500-1505 tonnes CO2e for synthetic turf) that will need mitigation. (See the Literature Review: Synthetic Turf carbon footprint, environmental, health, microplastics and biodiversity impacts)
So what is the alternative to Plastic Grass?
Well constructed natural turf field with a carefully chosen grass cultivar to suit the usage and climate.
I have just read a study that was presented at Australian Water Assocation conference last June - Ozwater20 - by Dr Mick Battam (a soil scientist) and Dr Paul Lambie (an irrigation specialist). The study was on building natural turf fields using industrial grade compost. This improves player carrying capacity to about 35-37 hours per week with minimal wear. Their study is titled: Creating Sustainable Open Spaces - Using Compost to Deliver Liveability, Sustainability, Recreation and Economic Outcomes, and is available from Australian Water Assocation website.
The study paper concludes:
"Using compost to amend the soils on sports fields has been shown to improve soil fertility. The amendment of soils also reduces irrigation demand, with benefits to the water industry from water savings and increased resilience to drought. A natural turf field built with a wear tolerant turf cultivar and compost amended soil provides for more liveable cities and gives a superior economic outcome to synthetic turf alternatives."
Use of compost for sporting fields to increase their fertility, usage capacity and drought resilience is part of the circular economy. It could provide an outlet for Moreland's green bin food and organic waste collection after it has been through the industrial scale composting process. This is a no-brainer. Moreland Council should embrace this possible reuse of green waste for improving municipal sporting fields.
