Minimal Synthetic Inputs
Synthetic products leach into waterways, contaminate soils, impact biodiversity, and have high GHG footprints in scopes 1 and 3.
At Rustica, sustainability isn't just a goal, it's our foundation. From locally sourced organic ingredients to eco-conscious packaging and zero-waste practices, every step we take is driven by a commitment to a better future.
We take pride in celebrating the farmers who cultivate our grains and the mill that transforms them into our essential ingredient — flour.
With complete traceability, every stage of production adheres to the highest standards of sustainability. All information has been independently verified by Certified Sustainable Ltd, ensuring accuracy and accountability every step of the way.
This page summarises our Sustainable Impact Report. Inside the full document, you'll find an in-depth overview of our GHG Emissions data and a detailed ESG scorecard offering transparent insights into our Environmental, Social and Governance initiatives.
Our certification is independently audited and renewable. All data on this page is verified.

Certified Sustainable grain at 71.9 kg CO₂-eq per tonne, against the Australian conventional baseline of 315 kg CO₂-eq per tonne. Source: GRDC + CSIRO, Feb 2022.
Wholegrain Milling Co. Certified Sustainable Premium White Bakers Flour at 235 kg CO₂-eq per tonne, against conventional flour at 495 kg CO₂-eq per tonne.
Our 900g White Sourdough at 1.50 kg CO₂-eq per kg, versus conventional artisan bread at 1.93 kg CO₂-eq per kg. This loaf is 24% of our production.
Lower emissions is the headline. But the most important difference is what's actually in the loaf — and what isn't.
Every Certified Sustainable grain crop is rigorously tested for Maximum Residue Limits (MRLs), under NRS Program 49 and glyphosate analysis across more than 270 analytes. All grains are certified non-GMO, adhering to the highest food safety requirements.
Certified Sustainable Wheat surpasses conventional wheat in 9 of 11 key minerals tested. And Wholegrain Milling's Sustainable Bakers Flour outperforms Australia's leading conventional bakers' flour with 112% the protein content — enhancing dough strength and consistency for superior baking, and supporting muscle and bone health for the consumer.
Founded in 1978 by Wendy and Harry Neale in Gunnedah, NSW. Their story began with a small bench-mounted stone mill on their kitchen table.
Over time, they have grown into Australia's leading producer of sustainable, high-quality, organic flours. Sourcing premium, sustainably grown Australian grains is their priority. Through the Certified Sustainable program, they ensure transparency, traceability, and accountability, working with farmers to secure the finest grains while supporting regenerative practices that reduce carbon emissions and promote soil health.
Wholegrain Milling Co.'s commitment to sustainability includes collaborating with farmers who prioritise ecosystem health. Their dedication to sustainable, high-quality flour production aligns perfectly with our values, ensuring every loaf we bake is not only delicious but also a step toward a healthier and more prosperous future.
Certified Sustainable farms implement at least ten sustainable land management practices to enhance soil stability, water cycles, and climate outcomes. The farms supplying Wholegrain Milling Co. have provided evidence of the following:
Synthetic products leach into waterways, contaminate soils, impact biodiversity, and have high GHG footprints in scopes 1 and 3.
Routine soil tillage has detrimental effects on soil structure, soil biology and soil organic carbon, emitting CO₂.
Keeping optimum cover on the soil helps reduce evaporation, keeps the soil cool and provides food and habitat for microorganisms.
Strong crop rotations benefit soil structure, break disease cycles, and can provide valuable natural nutrients.
Water-use strategies optimise for efficient and effective rainfall infiltration and reduced evaporation. Safe runoff for streams and waterways.
Cover crops provide soil cover, living roots in soil, biomass for biological breakdown, and increase biodiversity.
Evaluation of resources used (plant, equipment, energy inputs), their scope 1, 2 and 3 emissions and useful lifespan to enact responsible resource use.
Soil biology plays an important role in cycling carbon and nutrients as well as providing the "glue" that forms good soil structure.
Technology assisted application of inputs to reduce resource use and potential environmental harms.
Keeping cover on the soil helps reduce evaporation, keeps the soil cool, and provides food and habitat for microorganisms.
