Compost Vs Landfill: Why Composting Is A Better Option π±
Compost Vs Landfill π±: Composting is a more viable option than sending waste to landfill for a few, valid reasons. Find out those reasons by reading this blog.
Across Australia, we send millions of tonnes of food scraps, grass/garden clippings and other organic materials to landfill each year. In fact, we sent a staggering 6.2 million tonnes of organic waste to landfill last year. This accounts for more than 40 per cent of the total organic waste Australia produced.
At first glance, it might seem harmless β organic matter breaks down eventually, right? But when you compare food waste in landfill vs compost, the differences are dramatic.
Burying organics in landfill creates environmental and financial burdens. Composting, especially at commercial and municipal scales, transforms this waste into a valuable resource. Itβs the kind of shift that changes systems β not just habits.

Compost vs landfill: a critical choice
In landfills, organic waste breaks down without oxygen, producing methaneβa greenhouse gas over 25 times more potent than carbon dioxide. This process contributes significantly to climate change and creates leachate that can contaminate soil and waterways.
Composting, on the other hand, is an aerobic process (with oxygen). It avoids methane production and results in nutrient-rich compost that improves soil health.
The choice between composting vs landfill is really a choice between:
- Emissions and pollution vs regeneration and soil health
- A linear system vs a circular one
- Long-term costs vs long-term gains
Scaling up: why large-scale composting matters
Whilst household composting plays a role, the greatest impact happens at scale. Councils, food businesses, shopping centres and universities generate huge volumes of organic waste. Properly collected and processed, this material becomes a local assetβnot a landfill burden.
In this context, composting vs landfill isnβt just an environmental issue β itβs an economic and community one. Composting creates jobs, supports agriculture and reduces the cost of managing overflowing landfills. Plus, in drought-prone regions like many parts of Australia, compost-enriched soil helps retain water, reducing irrigation needs.
Understanding the food waste problem
When you talk about composting or organic waste, of course, food waste also comes to mind.
Food waste is one of the most avoidable and yet most damaging forms of waste we generate. In Australia, over 7 million tonnes of food are wasted each yearβmuch of it still perfectly edible. This isnβt just an issue of wasted meals; itβs also a waste of the resources used to produce that food β land, water, energy and labour.
When food is discarded, weβre not just losing the product β weβre throwing away everything that went into making it. And when it ends up in landfill, it doesnβt just disappear. It breaks down in a harmful way, releasing methane and contributing to climate change.
Solving the food waste problem starts with prevention, but once the food is no longer edible, composting offers a smart and sustainable alternative.
Food waste in landfill vs compost: two very different outcomes
Letβs break down what happens to food scraps depending on where they go.
In landfill, food waste is compacted under heaps of mixed garbage, where it decomposes without access to oxygen. This anaerobic breakdown process emits methane β a highly potent greenhouse gas that contributes more to global warming than carbon dioxide.
Additionally, landfills generate leachate, a toxic liquid that can seep into the ground and pollute nearby water systems. Whatβs more, all the nutrients, carbon and organic value in the food are wasted β locked away in a site designed to bury, not renew.
In compost, food waste is handled in a controlled, oxygen-rich environment where it decomposes aerobically. Instead of releasing methane, it breaks down into a rich compost that replenishes the soil, enhances its structure and boosts its water retention. This compost can then support farms, gardens and reforestation projectsβclosing the nutrient loop.
This is not just a technical difference β itβs a systemic one. Landfilling creates a dead end; composting gives food waste a second life. With every banana peel or coffee ground redirected from landfill, we reduce emissions and build a healthier foundation for future growth.
Itβs a simple shift with a big payoff. Instead of becoming part of the problem, food waste becomes part of the solution.
Compost vs landfill: councils and businesses have a key role
Across Australia, more local governments are rolling out FOGO (Food Organics, Garden Organics) collection services, making it easier for households to participate. But businesses β especially in hospitality, retail and events β can lead the way in volume and visibility.
Hereβs how they can help:
- Provide clear bin systems to separate organic waste from general rubbish
- Train staff and engage customers in proper sorting
- Partner with composting services to ensure collected organics are processed properly
Every food court tray or prep bench that diverts scraps from landfill contributes to a cleaner, more circular system.
Households can help, too
If your council offers green bins, use them. Learn what can and canβt go in β usually, fruit and vegetable scraps, coffee grounds, eggshells and garden cuttings are all fine. Keep contamination (like plastic or meat) out, and youβll be doing your bit.
Even without a backyard compost pile, households can:
- Reduce food waste through better planning and storage
- Encourage local leaders to support composting programs
- Help normalise organics recycling in apartments and shared living spaces
Composting with Waster
At Waster, weβre proud to support Australian businesses in diverting their food waste from landfill. Our organic food waste bin services make it easy for companies of all sizes to participate in commercial composting.
We collect food waste and transport it to local composting facilities, where itβs turned into a valuable soil product. This helps reduce methane emissions, lowers landfill costs and supports regenerative agriculture.
Whether you run a cafe, office kitchen or industrial site, Waster makes composting accessible and practical!
Wasterβs final thoughts: letβs move from waste to resource!
The facts are clear. When comparing compost vs landfill, composting wins β environmentally, economically and socially. Landfilling food waste means sealing off its potential. Composting releases it.
Whether youβre a local council, a business owner or a household, you can play a role in making that shift. Itβs not just about what we throw awayβitβs about what we choose to do with it.
