NZ-EU trade agreement is great news for sustainability

It’s been a long time coming! In July, New Zealand signed a free trade agreement (FTA) with the European Union. Good news for manufacturers too. New Zealand’s exports of goods to its fourth largest trading partner were worth NZD4.68b in 2022. These goods included many manufactured products – machinery, medical appliances, food products, plastics, aluminium and others. More than 91% of New Zealand’s trade into the EU will enter duty-free when the FTA comes into force (expected to be in the first half of 2024). Many goods, including some manufactured products, will have no tariffs at all from this date. This means many millions of dollars of tariff savings each year on exports to the EU. After seven years, when the agreement is fully in place, 97% of current trade will enter the EU duty-free. How the new FTA promotes sustainability The FTA will make trade more sustainable and create opportunities for businesses that deliver more sustainable products. The agreement is the first FTA built around the EU’s ’Together for Green and Just Growth’ approach to trade and sustainable development. It contains ambitious sustainable trade outcomes in many areas. Environmental outcomes include addressing climate change and subsidies on fossil fuel. Social outcomes include promoting labour rights and women’s economic empowerment. The upside for manufacturers – and some warnings The FTA will have a big impact on trade between New Zealand and the EU. The potential upside for local manufacturers is significant: easier access to one of the world’s most lucrative trading blocs; lower costs for materials imported from the EU. However, the FTA comes with warnings too. Firstly, local manufacturers will be competing with EU manufacturers who may have been making their products more sustainable for some years. As customers here and in the EU prioritise ‘responsible purchasing’, make sure […]

Using single-use packaging in your business – read on

– Natalie Martin, 3R Group Materials Innovation Manager Rightly or wrongly, single-use plastic packaging gets the lion’s share of attention in terms of sustainability and waste reduction. While much of this is focused on consumer goods, it’s far from a problem faced exclusively by retailers. Single-use plastic packaging is so pervasive throughout supply chains that just about all industry members deal with it in some way or form. As a result, they will all be affected by regulations aimed at reducing plastic waste, increasing recyclability and getting an industry-funded, regulated product stewardship scheme off the ground. In July 2020 single-use plastic packaging was declared a priority product under the Waste Minimisation Act 2008. This means it’s one of the six product categories that must have regulated product stewardship schemes established. 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. Why single-use plastic packaging? This product category is by far the widest ranging of those declared priority products, covering thousands of products. Plastic also isn’t simply ‘plastic’ but is split into seven different types depending on its chemical makeup. That makes recycling it, or even establishing collection systems much more complicated. Its negative environmental impacts when littered are well documented and are most frequently in the public eye. Despite this, single-use plastic packaging has an important role to play in reducing waste by keeping food fresh and safe and preventing goods from being damaged. It’s low weight and durability means it can also offer a lower carbon footprint than other materials when it comes to transport. In line with circular economy principles, the key is to ensure its use is minimised, that it’s used as effectively as possible and then recovered and recycled. […]

Circular economy: so much more than recycling!

Article: Part one The circle has been an important symbol since early times. To many ancient Eastern and Western civilisations, it represented unity, balance and stability. Fast forward to 2023 and the circle is the most talked about shape in sustainability. Why? Because it’s time to get serious about the circular economy and the business, environmental and social benefits it offers. What is ‘circular economy’? Circular economy (CE) is an economic system that can help your manufacturing business reduce risks and costs, become more resilient and build your brand. It can also help you identify new income streams. CE decouples using resources from economic growth. It recognises that the ‘linear’ economic system we use to produce and consume goods and services – ‘take-make-dispose’ – cannot go on forever. As manufacturers, you know that the resources you use are finite (‘take’). You may be facing shortages or skyrocketing prices, particularly with critical materials like lithium. Many of you will be looking for a more sustainable way to manufacture your product (‘make’). You may be concerned about what happens when consumers dispose of your product (‘dispose’). Are you contributing to landfilled waste? Could you be liable? Enter circular economy and solutions to these problems. Circular economy is based on three principles Principle 1: keep products and materials in use Circulating products and materials means keeping them in use at their highest value. It avoids the costs of extracting and creating materials, and of disposing of waste. A circular product is one that consumers can use for as long as possible (e.g. it is easy to repair). When the product wears out, its parts can be reused, or the product remanufactured (remade). At the end of the product’s life, its raw materials can be fully recycled. Principle 2: design out waste and pollution […]

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 […]
