Reduce your carbon footprint with Big Hanna commercial composters

Composting onsite with Big Hanna Composter can reduce the carbon footprint of your business. If food waste is dumped into landfill the food waste rots and produces the hydrocarbon methane, a potent greenhouse gas and source of climate change. Methane has 25 times more impact on climate change than carbon dioxide itself.

If you want to make meaningful carbon emission reductions under certified carbon footprinting or eco-labelling schemes like CarboNZero, CEMARS or Qualmark Enviro, Big Hanna Composter will help you take action. Big Hanna Composter does this because landfilling food waste can contribute to your carbon footprint, whereas the Big Hanna Composter uses the aerobic composting process. This results in a smaller carbon footprint compared to landfill. If your sustainable value chain partners are asking what your business is doing about your carbon footprint, show them a Big Hanna Composter working at your business!

If you’re an architect, urban designer or property developer looking for Green Star points and food waste recycling or carbon footprint reduction is an opportunity, consider onsite composting with Big Hanna Composter.

Calculating your carbon footprint can be a valuable step in reducing your carbon footprint – the old saying, ‘what gets measured, gets done’ still holds true. Below is the potential reduction in your annual carbon footprint in metric tonnes of carbon dioxide equivalents (MTCO2e) every year compared to landfill1 .
