Regulated product stewardship driving transition to a circular economy

By Trevor Tutt – GM Innovation, 3R Group Something which will affect almost all New Zealand businesses has mostly flown under the radar since it was announced during the covid pandemic. A swath of products are set to fall under regulated product stewardship for the first time in New Zealand after they were announced as priority products in July 2020. This means, for the first time in Aotearoa New Zealand, regulated product stewardship schemes are being established for tyres, electronic waste, single-use plastic packaging, synthetic refrigerant gases, agricultural plastics, and agrichemicals. So, if you rely on refrigeration, transport, electronics, or plastic packaging for your goods, you may be affected. It’s a big range of products, with more likely to be announced following government consultation on ways to accelerate product stewardship in new waste legislation. What is regulated stewardship? Product stewardship sees scheme members contribute towards the collection of their products at the end of life so they can be reused, recycled or properly disposed of. This usually means a stewardship fee is charged at the point of manufacture or import and is used by a scheme to achieve better environmental outcomes. The pay-off is improved environmental performance and brand reputation, as well as reduced risk from environmental harm. New Zealand has several voluntary stewardship schemes where participation is just as the name suggests – voluntary. These can suffer from limitations due to insufficient data and resources, and free riders – those who don’t contribute but whose products are stewarded through the scheme. Regulated stewardship sees all of industry required to participate. This provides a level playing field with no free riders. Schemes are therefore better resourced financially and through industry support such as knowledge sharing and collaboration. Data capture is also greatly improved. Regulated schemes are better equipped to reduce […]

Where to for sustainability in an economic downturn?

-Dr. Barbara Nebel, CEO, thinkstep-anz Is sustainability a ‘fair weather friend’ in your manufacturing business? Do you see it as something to cut back when recession calls? If so, you’re missing a business opportunity. Building a more environmentally and socially sustainable business can make your business more efficient and resilient and help you weather the storms ahead. The New Zealand government is forecasting a recession in 2023. This is difficult news for manufacturers already challenged by creaky supply chains and a tight market for skills. Make the most of the many opportunities sustainability offers. Business benefit: reduce your costs Understand your environmental impacts – and reduce them Everything that goes into making your product has an environmental footprint – and a dollar cost. Start by understanding your footprint. A Product Carbon Footprint study measures the carbon your products generate. A Life Cycle Assessment (LCA) considers other impacts too, including the water you use and the waste you generate. Food manufacturer Comvita’s LCA NZ Manufacturer October 2022 by Media Hawkes Bay Limited – Issuu will help the business understand the environmental impacts of its ‘honey in a pot’, from growing the mānuka forests the bees feed on to disposing of the honey’s empty packaging. Armed with information about your environmental impacts, look at whether you can cut some costs. Can you reduce the amount of energy you use? Use raw materials more efficiently? Cut the waste you generate and the costs of disposing of it? The beauty of LCA is that it shows trade-offs. It will help you understand how tweaking one aspect of your product (e.g. the energy you use) affects other aspects (e.g the waste you generate). Buy responsibly Purchasing goods and services produced in environmentally and socially responsible ways can save you money. For example, buying from local […]

More sustainable and productive steel turning with new carbide inserts

A recent survey by OpenText found that 92% of manufacturers consider corporate social responsibility (CSR) to be important for their overall reputation in the markets. Even though steel turning is, by nature, a waste producing process, it is possible for manufacturers to improve their sustainability without compromising process security — even against the unprecedented challenges of COVID-19. Here is a different approach to steel turning. According to the 17 Global Goals for Sustainable Development set out by the United Nations (UN), manufacturers are expected to minimise their environmental impact while going further than just optimising energy use. Although CSR is important to companies,manufacturers waste between 10% to 30% of material in their machining processes, with a typical machining efficiency of below 50%, which includes at the design, planning and cutting phases. So, what can manufacturers do? The UN’s goals recommend two main avenues that take into account such factors as a growing population, finite resources and the linear economy. The first is to address these challenges with technology. Industry 4.0 concepts — like cyber physical systems, big data or the Internet of Things (IoT) — are frequently cited as being the way forward for manufacturers seeking to reduce waste. Yet, this does not allow for the fact that most manufacturers are yet to apply modern machines with digital capabilities to their steel turning operations. Most manufacturers are aware of how important the choice of insert grade is for making steel turning more efficient and productive; and how this affects overall performance and tool life. However, many are missing a trick by not considering the whole tooling concept; everything from advanced inserts, tool-holders and easy-to-adopt digital solutions. Each of these factors can help to make steel turning more sustainable by reducing energy consumption and minimising waste. Reduced cutting speeds Manufacturers face […]

Seven good news sustainability stories in manufacturing in 2022

-Dr Barbara Nebel, thinkstep-anz As 2022 draws to a close, it’s time to spread a little Christmas cheer. Here are seven good news stories that show the progress the manufacturing sector made this year to become more sustainable. We have a national Emissions Reduction Plan In June the government introduced New Zealand’s first Emissions Reduction Plan (ERP). The ERP sets the context for sustainability in New Zealand. It contains the strategies and policies that will make our Zero Carbon Act 2019 happen and move all industries, including manufacturing, to a low-emissions economy over the next three decades. ‘Carrots and sticks’ will encourage (and require) manufacturers to cut greenhouse gas emissions in the products they make, the heavy transport, freight, energy and buildings they use, and the waste they discard. Our June article provides more information. NZ Manufacturer June 2022 by Media Hawkes Bay Limited – Issuu Manufacturers are measuring their products’ environmental impacts We’re encouraged to see more manufacturers, in more industries, investing in Life Cycle Assessment (LCA) for their products and packaging. LCA measures a product’s environmental footprint: from sourcing (and maybe growing) the raw materials, to making the product, to using it and disposing of it at the end of its life. LCA can measure many impacts, including the energy and water used and the carbon released (the product’s ‘carbon footprint’). Food manufacturer Comvita has commissioned an LCA. The company wants to understand how to reduce the carbon footprint of its honey at all stages of the product’s life cycle. Manufacturers are communicating their products’ environmental impacts The list of registered Environmental Product Declarations (EPDs) for New Zealand-made products continues to grow strongly. An EPD is a verified, publicly available document that summarises a product’s environmental footprint. EPDs start life as LCAs. There are EPDs for many products […]

Winstone Wallboards uses circular economy to reduce carbon emissions in plasterboard

-thinkstep-anz Circular economy thinking is helping Winstone Wallboards (WWB) reduce carbon in Aotearoa New Zealand’s built environment. Around 15% of our country’s greenhouse gas (carbon) emissions relate to our buildings. Knowing that construction waste contributes heavily to these emissions, WWB set itself a challenge. WWB manufactures plasterboard under the GIB® brand. It is New Zealand’s only manufacturer of this product. The company wanted to reduce plasterboard wasted in construction across New Zealand by 30% without changing the design of its product. Its Designing out Waste programme (supported by the Ministry for the Environment, Canterbury Joint Waste Committee, Auckland Council, WasteMINZ, AUT and BRANZ) and circular economy practices have helped WWB reduce waste, emissions, costs and business risks and build relationships and the resilience in the industry. The circular economy The circular economy changes how we produce and consume goods. It designs out waste and pollution, keeps products and materials in use, and regenerates natural systems. In a circular economy, sending construction waste to landfill is a ‘leakage’ from the product’s ‘system’ (the processes involved in converting inputs to outputs). Identifying five carbon ‘hotspots’ in plasterboard Our thinkstep-anz team helped WWB identify five ‘hotspots’ of greenhouse gas emissions (GHGs) for construction waste across their product’s lifecycle. The diagram below shows the emissions created when the manufacturer makes and transports its product to its customers, and when its customers use and dispose of the plasterboard. The emissions these activities release are examples of ‘embodied carbon’ in building products. The link between all these sources of emissions? Waste. Circular economy: designing out waste on building sites On an average residential building site, around 23% of all materials, including 700kg of plasterboard waste, end up in a skip bound for landfill (source: Wastage Rate Report (Construction Resources and Waste Platform), REBRI – BRANZ). Much […]

NanoLayr’s sustainability roadmap charts the way

Article from Dr.Barbara Nebel,CEO, thinkstep-anz www.thinkstep-anz.com Want to make your manufacturing business more environmentally and socially sustainable? When you’re a busy manufacturer, investing in a sustainability roadmap can be the difference between talking about sustainability and making it happen. In this article we explain what a sustainability roadmap is and why your business needs one. We also talk with Auckland-based functional textile manufacturer NanoLayr about the benefits it’s seeing from theirs. What is a sustainability roadmap? A sustainability roadmap charts the course your business plans to take to become more environmentally and socially sustainable. Think of it like a Google map. Plug in your destination (a more sustainable manufacturing business) and Google offers up a host of ideas to help you with your journey. Street names and directions? These are the high-level sustainability actions you need to take to reach your destination. In a manufacturing business they may include sourcing renewable materials or tackling waste in your packaging. Alternative routes? Think of these as your options and trade-offs. There are many ways to become more sustainable. You’ll need to assess different projects and prioritise them. Distances and different modes of transport? These are the resources you’ll need to commit and the people you’ll need to involve: team members with clear responsibilities, external stakeholders such as suppliers, and (probably) some budget. Journey times? They’re the high-level timelines you’ll work to. Map your sustainability actions into blocks of time. You may be able to complete some within six months to a year. Other activities will take longer. Assign them over the medium term (say one to two years) and longer term (say two years plus). Bring this ‘journey’ information together and you have your sustainability roadmap: a summary of your sustainability goals and the projects, resources and timetable that will help […]

igus advances circular economy with e-chain made of recycled material

In the picture:More sustainability with consistent quality: The new world first cradle-chain made of recycled material conserves resources and drives the circular economy forward. Conserving resources and extending the product life cycle – this is the goal igus is pursuing with the new E2.1.CG cradle-chain from Treotham. Cradle-to-cradle: This is the principle of the circular economy, which is abased on nature. The aim: to return consumer goods to the biological or technical cycle in order to conserve valuable resources and raw materials. The motion plastics specialist igus is also pursuing this goal and has now developed the world’s first energy chain made from recycled material on the basis of its own “chainge” e-chain recycling program. From extreme weather and natural hazards to marine pollution, the climate crisis is getting worse and more and more people are becoming aware of it. “Even the purchasing decisions of our customers are increasingly being shaped by ecological considerations. That is why we have put a lot of effort into product development in order to be able to produce more resource-efficiently – without sacrificing product quality,” explains Jörg Ottersbach, Head of the igus e-chains Business Unit. The result: the E2.1.CG cradle-chain – a complete range of e-chains made from the new igumid CG material. Numerous laboratory tests show that the new e-chain has almost the same technical properties and load limits as an energy chain made from the standard igumid G material. The new range is available from Treotham in five series and 28 chain types. From discarded e-chain to recycled material The cradle-chain uses, among other things, recycled material from the “chainge” recycling program. As part of this program, igus has been collecting used energy chains from customers since 2019 so they do not end up in industrial waste. This service is offered […]

IoT helps glass manufacturer disrupt industry with four-day supply delivery

New Zealand glass manufacturer, Architectural Glass Products (AGP), has deployed Internet of Things (IoT) technology from Pollin8 and Thinxtra for around-the-clock tracking of its products and delivery trolleys, ensuring it avoids losing assets, and bolstering its industry leading customer service. AGP was founded in response to market demand for high quality glass that can be manufactured and delivered in short timeframes. Established in 2019, the company has become the nation’s largest manufacturer of insulated glass units (IGUs). It currently operates a four-hectare, highly automated factory in Hautapu on the North Island. AGP owns over 1,750 purpose-built delivery trolleys, worth NZ$3,000 each, to transport its fragile, high-value glass products. To reduce the risk of these assets going missing and ensure their efficient return to the facility, AGP installed low-cost IoT tracking devices from NZ’s Pollin8, which communicate over Thinxtra’s 0G Network. This allows the manufacturer to track assets in real-time so they can be retrieved efficiently to maintain its four-day order-to-delivery service. “Before AGP came to market, the time from ordering the glass to delivery was unpredictable, and customers never quite knew specifically when their products would arrive. We have completely disrupted the market by delivering in four days,” said Gene Sanford at AGP. “Having Pollin8 and Thinxtra’s joint IoT solution in place from the start has proved central to our ability to deliver this level of service. Rather than resorting to the time consuming task of counting assets on a map with a basic GPS solution, we have a dashboard and data that inform us which customer has the trolleys and how long they have had them, enabling us to quickly take action to maintain our high service levels. “Our customers’ cash flow can be improved significantly knowing their supply will be delivered on time; getting our assets back quickly […]

Power your future with clean, renewable energy

-Barbara Nebel, CEO thinkstep-anz Every manufacturer needs reliable, affordable energy. The electricity you use, the thermal energy or coal that powers your boilers, the liquid fuels that run your vehicles – energy is one of your business’ most important resources. So, let’s take your energy requirements a step further. Adding ‘clean, renewable energy’ to the list will make your manufacturing operations less dependent on fossil fuels and help avert climate catastrophe. Include a ‘resilient source of energy’ and you’ll help your business withstand potential energy shocks as geo-political tensions grow. Reliable. Affordable. Clean. Renewable. Resilient. That’s a lot to ask of an energy source! Or is it? In this article we show you how to get started – and where to look as you become more ambitious. 1. Start with the UN’s Sustainable Development Goals (SDGs) The 17 SDGs aim to end poverty, protect the planet, promote prosperity, and ensure peace for all. All 193 UN member states, including New Zealand, have adopted the goals. Based on our thinkstep-anz research, the Climate Change goal (SDG 13) is the top sustainability priority for companies in New Zealand and Australia – and maybe for your manufacturing business too. For many manufacturers, SDG 7 (Affordable and Clean Energy) will be another critical goal. SDG 7 and SDG 13 share some common targets: encouraging energy resilience, moving away from fossil fuels, and improving access to clean energy. Tackling either goal is a win for your business, our planet and its people. Operational efficiency + sustainable action together! Windmill on grass field during golden hour.

The share of renewables in New Zealand’s total primary energy supply is currently around 40% (MBIE, 2020). We’re not where we […]

Six tips for going circular (from manufacturers who are doing it)

-Jim Goddin, thinkstep-anz Every expert was once a beginner – and that includes the three New Zealand and Australian manufacturers who share their circular economy (CE) expertise here. Ged Finch, Jason Graham-Nye and David Bell run or work in manufacturing businesses based on CE principles. Ged is R&D Manager at XFrame, a business which designs and manufactures reusable prefabricated structural framing. Jason co-founded gDiapers which designs and makes compostable nappies. David is Manager Sustainability and Insight at steel recycler, manufacturer and distributor InfraBuild. Our three experts have learned a lot about CE since they started out. In a recent thinkstep-anz webinar, they shared their tips for taking a manufacturing business circular. Their advice is relevant for businesses that design and manufacture their own products and for contract manufacturers too. Before we hear from our experts, here’s a look at CE and how it can add value to your manufacturing business. Circular economy in a nutshell CE is often confused with recycling. It’s much (much!) more. CE is based on three principles. Here’s how they play out in the real world of product design and manufacturing at XFrame, gDiapers and InfraBuild. Principle 1: designing out waste and pollution XFrame estimates that their reusable framing can reduce construction waste from a single home by up to 5 tonnes. gDiapers’ products eliminate waste from disposable nappies. InfraBuild recycled 1.4 m tonnes of scrap metal in Australia in 2021. Principle 2: keeping products and materials in use More than 95% of the materials in an X-Frame building can be recovered and reused, many times. The materials in gDiapers’ nappies can be composted and put back into the soil. InfraBuild keep materials in use by feeding their electric arc furnaces with 100% scrap metal wherever possible. Principle 3: regenerating natural systems The timber XFrame use to manufacture […]
