An organic recycling business has accused the state government of being “in love with landfill” and believes stronger legislation could benefit WA farmers.
uncertain
legislation → accuse → farmers
C-Wise chief executive Greg Watts said the government is burying valuable nutrients that could be going back into local farms as growers continue to pay eye-watering prices for fertiliser.
uncertain
growers → say → fertiliser
It comes after WA Waste Authority figures released last month showed 2.7 million tonnes of waste was sent to landfill in 2024-25.
asserted
tonnes → come → 2024
In the Perth and Peel region, 27.5 per cent of waste went to landfill.
asserted
cent → go → landfill
“The figures are high because landfill is still the easy option in WA,” Watts said.
asserted
Watts → say → WA
“Instead of burying this waste, we should be recovering the nutrients in it and putting them back into our farms.”
asserted
we → bury → farms
“We’re throwing things into landfill that could be used again.”
uncertain
that → throw → landfill
C-Wise is an organic carbon recycling business based out of Nambeelup in Perth’s south.
asserted
Wise → base → south
“Basically, we identify organic waste streams coming out of other industries or sects of the community,” he said.
asserted
he → identify → community
“We aggregate them, process them through a fairly robust composting process, and that process spits out products like compost that you’ll see in saw yards, or as mulch.
asserted
you → aggregate → mulch
“What we’re aiming to do is to recover more of that from the community and then put it back out into our farmlands or into vegetables or other tree crops like grapes or avocados.
asserted
aiming → aim → grapes
”
Currently only two-thirds of metropolitan councils in Perth have introduced FOGO bins for organic waste.
asserted
thirds → introduce → waste
In August, the state government changed the rules over what could be put into green-lid bins.
uncertain
what → change → bins
Households are only allowed to place food scraps, garden waste and certified compostable caddy liners displaying the AS 4736 seedling logo in their FOGO bins.
asserted
Households → allow → bins
Items which were previously accepted such as tissues and paper towels, tea bags, and compostable takeaway packaging now have to go in the red-lidded general waste bins.
asserted
which → accept → bins
Watts said this is one of many instances where items could be salvaged for compost.
uncertain
items → say → compost
“In the city, we’re wasting a lot of our garden pruning and if you’ve only got two bins, they’re going to waste-to-energy,” he said.
asserted
he → waste → energy
“If you’ve got compostable cups, coffee grounds, food waste from kitchens, specific event waste where the food trucks rock up, they all have their own organic waste streams, but it all ends up into one bin that goes to landfill.
asserted
that → get → landfill
“There’s all these different events that we could capture these organic wastes a lot better.”
uncertain
we → ’ → wastes
Watts said recovering more nutrients locally could bring a circular economy to people like
He said the failure to look for another use for waste extends beyond what goes into landfill, with unsaleable commercial grain and dead chickens among the resources that are lost rather than recovered.
uncertain
that → say → resources
“That grain could be processed through a composting facility into a fertiliser replacement, but there’s no legislation to make that happen.
uncertain
that → process → replacement
Chicken mortalities just get buried on-farm.
asserted
mortalities → bury → farm
We need to do better, we’ve got all these resources we’re wasting,” he said.
asserted
he → need → resources
Narrogin farmer Ash Wiese trialled the compost from C-Wise and now uses it as part of his farm nutrition program.
“We did two or three years, just as a small trial basis, over 100 hectares of our farm, and after that, we were pretty convinced it was a good thing.
asserted
it → trialle → that
We’ve been doing our whole farm for the last three years,” Wiese told this masthead.
asserted
Wiese → do → masthead
“I really like the concept.
asserted
I → like → concept
I like the circular economy.
asserted
I → like → economy
We grow a lot of oats here for porridge for human consumption, and a lot of their compost is made from the waste when you de-hull an oat, and you’ve got this product left over.
asserted
you → grow → product
“They use a lot of that as the base of their compost.
asserted
They → use → compost
So I love the idea that they’re pulling nutrition from waste sources, and we’re burying it in the soil and growing food from it again.”
asserted
we → love → it
Wiese said the compost has the same effect on his crops as any other fertiliser he has used in the past and is equally cost-effective.
asserted
he → say → past
“From 50,000 houses worth of FOGO, we grow about 10,000 tons of oats, which is about 10 million bags of porridge, which is about 200 bags of porridge for every one of those households that would put the FOGO in,” he said.
asserted
he → grow → FOGO
“So it’s nice to think that if you’re putting a bag of FOGO out, you’re going to get more than a bag of porridge back.”
asserted
you → ’ → porridge
Wiese believed more farmers would be keen to use compost made from all types of nutrient filled waste.
asserted
farmers → believe → waste
“We’re all very conscious of building the nutrition in our soil and building the organic matter in our soil as well, and we’re definitely seeing that happen using the compost,” he said.
asserted
he → ’re → compost
Watts is now calling on the state government to draw a much harder line on landfill, to stop organic waste being buried when its nutrients could be recovered and put back into WA farms.
uncertain
nutrients → call → farms
Because if we make it more expensive to drop it in a hole, then people are going to invest in innovations to reduce that cost,” he said.
asserted
he → make → cost
“We know that money is the biggest driver in every community.
asserted
money → know → community
So you’ve got to follow the money.
asserted
you → get → money
“Now we’d like people to follow the carbon, but if they won’t follow the carbon, then they can follow the money, and we’ll be cheaper than landfill
asserted
we → like → landfill
