Westfalia Fruit has committed to using all parts of the avocado across the supply chain, including the skins and seeds, to make new, sustainable products.
Avocados imported for retail, food service and wholesale customers are carefully inspected and any unsuitable avocados are processed at Westfalia’s facility into products like avocado pulp, smashed avocado and guacamole.
However, the avocado skins and seeds from the process, previously typically used in low-value applications such as anaerobic digesters, are now finding new, higher-value alternative uses.
Having partnered with Efficiency Technologies, the value of the entire by-product channel of avocado skins and stones is assessed to optimise use, with the most recent development being a technology extracting a natural, sustainable dye from avocado stones, with SAGES London.
The process extracts perseorangin (a rare and sought-after natural pigment) from avocado stones collected at Westfalia’s UK facility. The pigment offers eight distinct shades ranging from light yellow to rich reddish-brown, creating new opportunities for sustainable colouring solutions across multiple industries.

The specialised extraction method isolates perseorangin, which constitutes approximately 3% of the avocado stone, and processes it into a dried powder form, providing extended shelf life.
“This breakthrough represents a significant step in our journey toward our total crop use strategy,” said Andrew Mitchell, Head of Group Innovation at Westfalia Fruit.
“By transforming what was once considered by-product into a valuable resource, we’re creating sustainable solutions that benefit multiple industries. The ability to produce eight distinct natural shades while maintaining our commitment to use the entire fruit demonstrates the potential of innovative thinking in sustainable agriculture.”
Besides the dye extraction, remaining materials from the avocado skins and stones are also processed into additional products — for example, starches are directed to paper manufacture as a precursor to packaging production, while ground materials find applications in cosmetics as natural exfoliants, as alternatives to micro-plastics.
The natural dye extraction process represents an advancement in sustainable practices, particularly as industries increasingly seek alternatives to synthetic dyes.
The powder format enables stability and ease of use across various applications, while the range of the eight distinct natural shades provide versatility for different product requirements.
This innovation comes at a time when consumer demand for natural, sustainable products continues to rise across fashion, beauty and packaging sectors. The pigment’s successful showcase at London Fashion Week highlighted its viability in sustainable fashion, while ongoing collaborations with industry leaders in cosmetics and packaging demonstrate its cross-sector appeal.
Plans are underway to understand how the technology could be expanded to additional Westfalia facilities in Europe, where more avocado by-product can be processed using the same techniques.
The company’s integrated operations enable efficient collection and processing of avocado stones and skins from multiple production sites, which will help to maximise the sustainable impact of the initiative and builds upon Westfalia’s commitment to sustainability and circular economy principles.

Siemens technology has helped Ashbridge Capital’s Riverside Centre in Adelaide reduce its energy consumption and emissions.
Controlled and monitored through Siemens’ leading Desigo CC Building Management System (BMS), Riverside has now become one of the few buildings of its age in Australia to achieve carbon neutrality. Originally built in 1987, the 22,000 m2 building is claimed to be the only office tower in South Australia fully certified carbon neutral.
By using Siemens technology, the Riverside Centre has reduced its electricity costs by 50%, energy consumption by 40% and emissions by 67.5%. It has also earned a 5.5 Star NABERS Energy rating.
Australian investment manager Ashbridge Capital, on behalf of German investor Atlantic Funds, planned to increase the building’s sustainability in 2020 with a $24 million investment, aiming to reduce the building’s carbon footprint through energy efficiency upgrades.
The investment manager partnered with Siemens on an Energy Performance Contract, which included modernising mechanical services including lift motors, smart metering, LED lighting upgrades and the installation of a solar panel system.
“The Riverside Centre, almost 40 years old, has been transformed into a carbon-neutral building with a 5.5 Star NABERS rating — an impressive achievement. We are exceptionally proud of these achievements, which validate that the Riverside Centre remains as relevant and competitive as any premium office building in Australia,” said Vishant Narayan, Founder and Managing Director of Ashbridge Capital. “Climate change is one of the most significant challenges of our time. The built environment produces around 40% of carbon emissions globally. As building owners, we have a duty of care not just to provide healthy and productive spaces for tenants, but to use the latest energy efficiency technology there is to help reduce our collective carbon emissions.
“Siemens has been a great technology partner on our sustainability journey. From the feasibility studies at the start through to supporting us in bringing some of the best-in-class building management technology, it has been a collaborative effort to get to where we are now. We basically hit every goal we wanted to and outperformed on energy performance by 250%.”
Part of the Siemens Xcelerator portfolio, Desigo CC is an open building management platform which is designed to manage high-performance buildings and adapt to future requirements.
Additionally, Siemens’ remote digital service centre in Melbourne provides real-time monitoring of the Riverside Centre, enabling the building to continue to operate at peak performance with a data-driven maintenance model.
Peter Halliday, CEO of Siemens Australia and New Zealand said, “Australia is responsible for 1% of the global greenhouse gas emissions — but by accelerating digitalisation across industry and infrastructure, we can achieve our greenhouse gas reduction targets faster, ease the burden on ambitious renewables targets and contribute more to decarbonising the world beyond 1%.
“The Riverside Centre is a great example. Technology upgrades have delivered energy savings that will pay for the upgrades over time. This is true sustainability and demonstrates that no matter a building’s age, we can use technologies available today to digitalise, become more sustainable and reduce operating costs.”
