Energy efficiency: a bright way to power up your savings!

From NZ Manufacturer magazine March 2025 www.nzmanufacturer.co.nz NZ Manufacturer March 25 by Media Hawkes Bay Limited – Issuu -Insa Errey, Advisor to NZ Manufacturer, Genesis, Senior Manager Future Fuels. Energy efficiency is increasingly becoming a key factor to drive cost reductions, especially in the manufacturing sector. As manufacturers seek ways to remain competitive and reduce operational expenses, energy costs should become the primary target for cost-cutting measures. By improving how energy is used, it can reduce bills, boost productivity, and contribute to long-term sustainability. The Link Between Energy Efficiency and Costs In manufacturing energy cost can account for up to 20% of total operational expenses, these costs can vary depending on the industry and the energy intensity of the product. Energy costs, in many cases, are second only to labour in terms of operational spending. Leading to improving energy efficiency delivering substantial financial benefits. Energy efficiency involves the reduction of energy consumption without compromising output or quality. The savings generated from these measures can translate directly into reduced operational costs and higher profit margins. Significant savings can be realised with low to no cost process optimisation. While other opportunities may involve initial investment which can seem significant, the return on investment (ROI) is often reached quickly through reduced energy costs. Global insights from the International Energy Agency (IEA) show that in some industries, energy efficiency projects can pay for themselves in as little as 2-3 years. Beyond immediate savings, energy efficiency improvements can provide long-term financial benefits. Energy efficiency can help mitigate the impact of rising energy prices, making it easier for manufacturers to predict future costs and avoid unexpected increases in energy expenses. Even small reductions in energy costs can make a big difference to the bottom line. Another consideration is that energy efficiency can also provide […]

Matter: The Magnificent Illusion -1st Edition

by Guido Tonelli What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter – the matter that makes up the Earth and the matter that makes up the Sun and other stars? When Democritus stated, between the fifth and fourth centuries BCE, that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter. Everything around us – the matter that forms rocks and planets, flowers and stars, even us – has very particular properties.These properties, which seem quite normal to us, are in fact very special, because the universe, whose evolution began almost fourteen billion years ago, is today a very cold environment. In this book, Guido Tonelli explains how elementary particles, which make up matter, combine into bizarre shapes to form correlated quantum states, primordial soups of quarks and gluons, or massive neutron stars. New questions that have emerged from the most recent research are answered: in what sense is the vacuum a material state? Why can space-time also vibrate and oscillate? Can elementary grains of space and time exist? What forms does matter assume inside large black holes? In clear and lively prose, Tonelli takes readers on an exhilarating journey into the latest discoveries of contemporary science, enabling them to see the universe, and themselves, in a new light.

How your business can benefit from the circular economy

From September issue of NZ Manufacturer www.nzmanufacturer.co.nz Small Business and Manufacturing Minister Andrew Bayly, along with Climate Change Minister Simon Watts, introduced a new MBIE report showing circular opportunities for the manufacturing sector. “Manufacturing is a sleeping giant for New Zealand’s economy; with the right tools and support, manufacturing has the potential to supercharge our economic growth,” Bayly said. “The manufacturing sector accounts for 10 per cent of GDP, 60 per cent of our exports, and employs 230,000 people.” Increasing demand for low-carbon-manufactured goods “Globally there is increasing demand for low-carbon manufactured products. Our agile and innovative manufacturers with their strong green reputation and access to relatively low-carbon electricity are well positioned to take advantage of this demand,” he added. Watts emphasises that the manufacturing sector is already heading in the right direction and is supporting New Zealand in meeting its climate change targets. However, there is still more to be done. “That’s why we are providing manufacturers with information to support them to adapt their business to be less carbon-intensive, with the launch of a new online toolbox, report and dataset.” Circular economy critical for future of manufacturing The circular economy is critical component of modern manufacturing. Adopting circular economy principles can help you to significantly reduce costs while making your business more sustainable. The circular economy (CE) is a concept that changes how we produce and consume goods. It uses systems thinking to design out waste and pollution, keep products and materials in use and regenerate natural systems. CE moves us away from the current ‘linear’ model of producing and consuming goods and services: ‘take-make-dispose’. It has economic, environmental and social benefits. It is also closely linked to the Bioeconomy, which uses renewable biological resources to produce food, products, and energy. […]

Reducing manufacturing emissions

Hon Andrew Bayly, Minister of Manufacturing Manufacturing is a significant sector for New Zealand. It employs 230,000 people and accounts for nearly 10 per cent of GDP and 60 per cent of exports. I often describe it as a “sleeping giant” for New Zealand’s economy, because its significance is not well understood. When I travel around the country promoting the manufacturing sector, one of the things I often remind people is that a career in manufacturing is a career in a highly advanced, technical field. A lesser-known fact is that approximately a quarter of all New Zealand’s business-led research and development comes from the manufacturing sector, meaning manufacturing is a key driver of innovation. However, to support this innovation, manufacturers need the right tools and resources. I know from talking to manufacturers that access to information and expert guidance on how to upskill and improve productivity is challenging. Which is why I was delighted to recently launch a set of tools to help empower manufacturers to grow their business and reduce their emissions. Emissions and waste mapping The first is a report that identifies and maps the manufacturing sector’s emissions and waste patterns. Titled ‘Mapping Emissions and Waste Stream Profiles, and Opportunities for Achieving Net-Zero Circular Advanced Manufacturing’, the report is based on waste and emissions data from 2019 (the most recent data available). It provides a comprehensive picture of waste, emissions, and opportunities to improve sustainability across the seven main manufacturing subsectors: food and beverage, machinery and equipment, other manufacturing, metal and metal products, chemicals and refining, wood and paper, and plastics and rubber. The report details challenges and opportunities for the sector with a goal of helping manufacturers identify opportunities to adopt low-emissions technology and increase circular manufacturing practices which, in turn, will help us reduce our […]

Harnessing the Power of Biogas: A Sustainable Opportunity for Industrial Manufacturing

From February issue of NZ Manufacturer -By Insa Errey While renewable energy has been making strides in various sectors, the potential of biogas in revolutionising industrial manufacturing remains largely untapped in New Zealand. This article explores the opportunities and benefits of exploring the opportunities of biogas in industrial processes. Biogas production involves the anaerobic digestion of organic materials such as agricultural residues, food waste, and wastewater. This process utilises microorganisms to degrade the organic material into methane. A byproduct from anaerobic digestion is digestate which can be utilised as biofertilisers. Reduction of Greenhouse Gas Emissions: Biogas utilisation has multiple advantage in reducing a site’s greenhouse gas emission. First, anaerobic digestion prevents the release of methane—a potent greenhouse gas—into the atmosphere. By capturing and utilising methane as biogas, greenhouse gas emissions from waste decomposition can be reduced. Secondly, biogas can be cleaned, known as green gas or biomethane. It can be used directly in on-site as process heat, reducing the need to purchase the required gas for heating from external parties and offering a cleaner alternative with lower carbon emissions. Waste Valorisation: The industrial sector generates substantial amounts of organic waste from processing residues that can end up in landfills or council wastewater treatment facilities. Biogas production provides a valuable solution by converting these waste materials into valuable energy and fertiliser resources. This waste valorisation not only reduces the environmental impact but also promotes a circular economy approach within the manufacturing process. Producing certified biofertiliser can contribute to increasing food production. Cost-Effective Energy Source: Biogas can serve as a cost-effective energy source for industrial manufacturing. By harnessing locally available organic waste, sites can create a steady and reliable source of useable energy, reducing dependence on traditional fossil fuels. Energy Independence: Most manufacturing sites rely heavily on external energy sources, making them […]

Navigating energy intensity and energy efficiency in manufacturing

-By Insa Errey In advanced manufacturing, the concepts of energy intensity and energy efficiency play crucial roles in influencing both operational costs and emissions profile. While both terms are interconnected, they represent distinct parts of energy management. Understanding these dynamics is crucial as businesses seek to balance production demands with the imperative of sustainable energy use. Energy Intensity in Manufacturing: A Measure of Production Impact Energy intensity is a measure of the energy consumed per unit of output, such as the energy required to produce a certain quantity of goods. Typically expressed in terms of energy units per unit of physical output. Energy intensity provides insight into the overall energy consumption patterns within a manufacturing facility. High energy intensity in manufacturing suggests that significant energy resources are being used to manufacture a product. High energy intensive processes may use a disproportionate amount of energy to achieve their production goals, signalling inefficiencies that can impact both costs and emissions. On the other hand, low energy intensity indicates a more efficient use of energy resources. Trending this even monthly will enable visibility of process operations, signalling if processes are running differently and have shifted. Energy Efficiency: Improving Manufacturing Practices Energy efficiency, on the other hand, focuses on optimising the utilisation of energy inputs to maximise output. It is the ratio of useful energy out to the total energy in. In manufacturing, energy efficiency measures the effectiveness of processes in converting energy resources into final products, emphasizing the opportunities to reduce loss and waste. Energy efficiency in manufacturing involves optimising processes and technologies to minimise energy consumption while maintaining or enhancing productivity. Improving energy efficiency in this context includes adopting advanced machinery, implementing effective energy management systems, and embracing best practices. Often invest is required such as conducting energy audits, energy transition plans […]

Carbon emissions on the way down

Robert McLachlan, Professor in Applied Mathematics, Massey University. Ian Mason, Adjunct Senior Fellow in Renewable Energy Systems Engineering, University of Canterbury. It may have been largely overlooked in the election debates, but New Zealand’s greenhouse gas emissions are finally on the way down. Annual emissions of carbon dioxide from the burning of fossil fuels are the lowest since 1999 and the 12-month renewable share of electricity is back above 90% for the first time since 1981. The Ministry for the Environment has advised New Zealand is on track to meet the first (2022-2025) carbon budget. All this can be attributed to a range of factors, including fossil gas running low, full hydro lakes, high petrol prices and working from home. But climate policies such as the Emissions Trading Scheme (NZ ETS), the clean car discount and the Climate Emergency Response Fund (CERF) have made a significant contribution to the turnaround. Current decarbonisation policies have and will continue to deliver real emissions cuts, provided they remain in place. It is therefore disconcerting that the National Party plans to take $2.3 billion from the CERF (almost two-thirds of the fund’s mid-2022 balance) to pay for tax cuts. The argument that individual households will use tax cuts to make their own decarbonisation decisions is unsupported by evidence and lacks credibility. The Labour Party has also dipped into this fund, taking $236 million to pay for rebates for household installations of solar panels and batteries, and community energy schemes. These may produce some as yet unquantified emissions cuts. Government funding is working Allocations from the Government Investment in Decarbonising Industry (GIDI) fund to NZ Steel and Fonterra show direct and measurable avoidance of emissions. The installation of an electric furnace at NZ Steel to utilise scrap will save 1% (800,000 tonnes of CO₂-equivalent emissions, or tCO₂e) of New Zealand’s 2021 gross emissions. Support for Fonterra […]

Serious about reducing your carbon footprint? Read on!

Chances are you’re already talking about carbon – and climate change too. If not, you need to start! But when you’re a busy manufacturer, getting to grips with carbon can be daunting, we know. So in this first of two articles, Head of Carbon at thinkstep-anz Nicky Andrews explains how to get started and keep making progress. Nicky Andrews, thinkstep-anz Head of Carbon. Understanding carbon emissions What are carbon emissions? ‘Carbon emissions’ is shorthand for ‘greenhouse gas emissions’ (GHGs) – the gases that are trapping heat in Earth’s atmosphere and warming our planet. There are many types of GHGs. Common ones include carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Why do manufacturers need to reduce carbon emissions? You’ll be helping to keep global warming to below 1.5°C and meeting the goals of the Paris Agreement. There are many good business reasons, too, for manufacturers to tackle carbon. How does my business benefit from reducing emissions? First up, you’ll reduce your risks. For example, if the government introduces a carbon tax, you’ll be prepared. You’ll strengthen your brand. Customers may already be asking what you’re doing to reduce your emissions. That’s because they (and their customers) are increasingly seeking lower-carbon products. You’ll strengthen relationships. For example, you’ll keep your investors happy if you manage your emissions (and their money) carefully. Your team will value your efforts too. Many people want to work for a business that takes climate action seriously. Finally, because winkling out carbon involves delving into everything you do, you’ll spot opportunities to reduce your costs. What are the three Scopes (types) of emissions? The international Greenhouse Gas Protocol is one of the standards that govern how organisations measure and reduce their carbon emissions. The Protocol splits carbon into three groups (Scopes). Diagram of the Scopes: thinkstep-anz, […]
