BusTech Group electric bus producer

BusTech Group is already running a number of its hybrid buses on the public transport network in Adelaide. Co-located with sister company Brabham Automotive in Adelaide, South Australia, BusTech Group is gearing up to produce at least 60 electric buses for the NSW Government over the next 18 months after its recent inclusion on a list of approved electric bus suppliers. It also has orders for electric buses in Queensland, which it aims to start delivering in the second half of this year. BusTech says it is the only Australian bus company locally manufacturing zero-emission buses for the NSW market. Its 12.5-metre ZDi electric bus has been designed, engineered and will be built in Australia. The all-electric buses aimed at the NSW market will use a Proterra battery pack and drivetrain following a partnership with the US company. Owned by South Australia-based Fusion Capital, which also owns Brabham Automotive, the company rebranded as BusTech Group in December following the purchase of Queensland-based Bustech by its Edinburgh-based Precision Buses in 2019. BusTech Group executive chairman Christian Reynolds said the two bus manufacturers first collaborated under a licensing agreement back in 2017. “We could see the opportunity to take more of a leading position within the bus space so we worked through a transaction to acquire Queensland-based business Bustech to look at more of a national manufacturing and supplier footprint,” he said. “Fusion Capital saw the opportunity from the closure of Holden to bring together Tier 1 supply capability to basically look at how we could create a business from the stalled capacity within the vehicle space and that’s what has allowed us to move quite quickly. “We went from four vehicles built in 2016 to a run rate now where we are building between 250 and 300 a year.” The company […]

Aqueous water heater ends hot water wait

With the average mains supply tap spitting out 10-15 litres of water a minute, it doesn’t take long to become a water waster. And if you are running cold water down the sink while waiting for the hot water to come down the pipe, it is not only wasteful but frustrating. This problem has become larger as pipe runs in households and businesses have become longer, as many premises get larger. Now, the water often has to run a lot further than before from the main water heater, before it comes out hot at the tap. And when you turn off the hot tap again, the hot water sucked into those long pipes cools down again. “It can become a double whammy – you waste more cold water running it down the sink while you spend more money heating it up to travel longer distances to get to you,” says Jay King, who has engineered a solution to the problem in the shape of Aus J’s ruggedly engineered Aqueous MK2 6-litre compact water heater. The Aqueous MK2 6-litre water heater from Aus J Hot Water Solutions is the most compact model yet, designed to provide domestic, commercial, hospitality, food and beverage, and industrial users with near-instant hot water while saving time, energy, water and frustration. With dimensions of just 305 by 305 by 304 mm, it is designed to sit snugly in cupboards near the tap, or under the floor just below them. It is so compact that it is also used in portable catering vehicles and boats, where space is precious, to ensure immediate hot water for washing, hygiene and convenience. Aqueous 6L and 10L models are available in 240v and 12v models, while the complementary Aus J Duoetto 10L water heater incorporates automatically switched 12v/240v operation. The compact […]

Students and SMEs hold key to ending waste

Robots that can sort e-waste ready for recycling and 100 per cent biodegradable food storage inspired by bananas are just two of the award-winning ideas from the inaugural India-Australia Circular Economy (I-ACE) Hackathon held this month, hosted by Australia’s national science agency, CSIRO, and NITI Aayog Atal Innovation Mission (AIM). Almost 80 teams of students and small and medium businesses from India and Australia turned their collective minds to solving the world’s global challenges with a focus on stopping waste and creating sustainable business practices. The concept of the I-ACE Hackathon originated last year at a virtual summit where the Prime Ministers of both countries committed to working together on circular economy innovation initiatives. Honourable Prime Minister of India Shri. Narendra Modi expressed his words of appreciation to the young innovators. “All participants of this circular economy hackathon are winners and commend your spirit to innovate in this time of COVID 19. We are not the owners of all that mother earth has to offer, but merely its trustees for all the future generations to come,” Prime Minister Shri. Narendra Modi stated. “We [India and Australia] must explore ways to scale up innovative ideas and must look at consumption patterns and reduce ecological impact, not only in two countries but for the whole world. “Recycling, reusing, eliminating waste and improving resource efficiency should become part of our lifestyle. “The Power of youth comes from openness to new ideas, innovation and ability to take risk. “The strong India and Australia relationship will play an important role in shaping the post covid world.” Teams of Australia and India’s brightest students and most innovative start-ups targeted problems such as reducing packaging waste, avoiding waste in food supply chains, reducing plastics waste, and recycling critical energy metals and e-waste. CSIRO Chief Executive Dr […]

Cleaning up renewable energy

Researchers at the University of South Australia are leading a national push to ensure the dream of renewable energy doesn’t become a nightmare of waste management. Australia has the highest proportion of household photovoltaic (PV) systems in the world, with more than 21 per cent of homes – or around 2.59 million – now possessing a solar energy system. With most PV systems paying themselves off in three to five years, the average 25-year life span of solar panels makes them an excellent investment, delivering a good return for decades after their cost is recovered. Eventually, however, all good things come to an end, and increasingly, industry experts are starting to ask what we’re going to do with all these solar panels when they are due to be replaced. In Australia alone it is estimated more than 100,000 tonnes of solar panels will enter the national waste stream by 2035. Solar energy expert, Professor Peter Majewski, is leading research at UniSA’s Future Industries Institute (FII) to help establish a lifetime stewardship scheme for Australia’s PV industry, ensuring end-of-life strategies are in place long before solar waste peaks. “We have time to plan for this and ensure the processes are in place, but we have to start acting now, as the right practices may take some time to implement,” Prof Majewski says. “There are good stewardship programs in place for products such as paint and tyres in Australia, and we would like to see a similar system in place for solar, where the disposal process is pre-planned as an integral part of the product lifecycle.” While retired solar panels are relatively safe and stable, they are classified as e-waste, meaning they cannot be put into landfill in Victoria. With similar bans likely to follow in other states, the need for alternative […]

Rio Tinto connects the Pilbara to Asia with new direct freight shipping service

Rio Tinto has secured a new commercial freight shipping service connecting Western Australia’s Pilbara region to the major international shipping hub of Singapore. The service will provide the company with a quicker, cheaper and cleaner alternative to the existing freight delivery route via Perth, helping to drive regional economic development and local job creation. The regular freight service commenced with the arrival of the MCP Graz at the Port of Dampier from Singapore. The vessel delivered essential maintenance supplies for Rio Tinto Iron Ore’s operations in the Pilbara, including rail wagon wheels, wagon parts, oil and lubricants. Future shipments are expected to include tyres for heavy earth moving equipment, conveyor belts, rail wagon and locomotive parts and mining consumables. The service is also open for use by local businesses in the north-west of Australia, providing companies operating in the region with better access to international markets and more efficient movement of freight. Rio Tinto Iron Ore managing director of Port, Rail and Core Services, Richard Cohen, said, “This is an important new service that connects the Pilbara to the rest of the world via the major international shipping hub of Singapore. It will provide a number of benefits by delivering cheaper, cleaner and faster freight to the region. “It is an important breakthrough not only for our business, but it will also provide a great opportunity for the local Pilbara economy by helping to unlock small business growth and supporting job creation.” Rio Tinto expects the service to reduce the lead-time for goods in to the Pilbara by six to 10 days compared with freight via Fremantle. Additionally, it’s expected to provide an annual saving of around three million litres of diesel fuel by reducing road train travel from Perth by more than 3.8 million kilometres. Over time, Rio Tinto […]

Time for change

Australia is the world’s largest producer of bauxite — the ore that is chemically processed to produce alumina — and has numerous aluminium refineries and smelters across the country. Australia’s dependence on aluminium is evident in all areas of infrastructure — even windows and doors. However, the high energy costs of aluminium smelters are driving the market towards new materials.. Since the first aluminium smelter opened in Tasmania in 1955, the aluminium industry has been a key contributor to the Australian economy. As of 2018, the industry produced 96 million tons of aluminium bauxite. While the volume of aluminium offers opportunities for a range of sectors and products, its production is carbon emitting. Reducing emissions from aluminium production is a challenge of its own but replacing some of its uses with composites can help create more sustainable buildings. Composites such as fibreglass are already used in building applications such as roof, wall and floor insulation — though composite windows and doors are still a rare sight in Australia. Thermal insulation Summer temperatures frequently reach 40 degrees Celsius, so air conditioning is a vital system to help keep buildings cool. In fact, it’s thought that 49 per cent of Australians have some form of air conditioning unit in their homes. However, air conditioning requires a lot of power to run. The average central air conditioning unit uses 3,000 to 5,000 watts of power for nine hours of cooling a day. According to Australian electricity provider Blue NRG, ten per cent of the world’s energy use is spent on air conditioning. A typical home loses around 40 per cent of its energy through windows and doors. If a building’s entry and exit points are not thermally efficient, all that cool air risks — quite literally — going out the door. Aluminium is a […]

Digilin celebrates 40 years

The Australian lighting and controls manufacturer is celebrating four decades since its founding with a refresh to its brand image and new website. Digilin has manufactured LED, lighting control and fibre optic products for some of the country’s most iconic landmarks, such as the Melbourne Arts Centre Spire, the Adelaide Convention Centre and Brisbane’s Kingsford Smith Drive. “As an engineering and technology focused company, we’ve generally let our product’s performance do the talking for us, however, moving forward we feel it’s also important that our image reflects well on our work and supports our partners”, said Tremaine Wrigley, Digilin’s GM, in a statement. Tremaine says that by stating that “despite the visual changes to our brand, our core values and commitment to manufacturing world-class lighting and control technologies right here in Australia remains the same.” Digilin has always embraced the benefits and challenges of onshore manufacturing, opting to support its client base with Australian made innovations and local support. Digilin expresses confidence in its approach and continues to invest in the latest engineering and production equipment for the new facility it moved to in 2019.

Coal is passé in much of China

Australian coal exports to China plummeted last year. While this is due in part to recent trade tensions between Australia and China, our research suggests coal plant closures are a bigger threat to Australia’s export coal in the long term. China unofficially banned Australian coal in mid-2020. Some 70 ships carrying Australian coal have reportedly been unable to unload in China since October. This is obviously bad news for Australia’s coal exporters. But even if the ban is lifted, there’s no guarantee China will start buying Australian coal again – at least not in huge volumes. China is changing. It’s announced a firm date to reach net-zero emissions, and governments in eastern provinces don’t want polluting coal plants taking up prime real estate. It’s time Australia faced reality, and reconsidered its coal export future. First, the coal ban In May last year, China’s government effectively banned the import of Australian coal, by applying stringent import quotas. As of last month coal exports to China from Newcastle, Australia’s busiest coal exporting port, had ceased. In 2019, Australia exported A$13.7 billion worth of coal to China. This comprised A$9.7 billion in metallurgical coal for steel making and A$4 billion in thermal coal for electricity generation. The latest official Australian data shows these export levels fell dramatically between November 2019 and November 2020. Comparing the two months, metallurgical and thermal coal exports to China were down 85% and 83% respectively. Several Chinese provinces experienced power blackouts in late 2020. China’s state-backed media said the shortages were unrelated to the ban on Australian coal. Instead, they blamed cold weather and the recovery in industrial activity after the pandemic. We dispute this claim. While Australian coal accounts for only about 2% of coal consumption in China, it helps maintain reliable supply for many power stations in China’s southeast coastal provinces. Coal mining in China mostly occurs in the western […]

Achieving carbon neutrality: One company’s lessons learned

– Eric Rondolat, CEO, Signify Committing to carbon neutrality can trigger wide-ranging changes in how any company operates. Lessons learned from Signify can help any company understand the challenges and opportunities ahead when tackling emissions. Signify, formerly the lighting business of Philips, achieved carbon neutrality last September, delivering on a promise forged at COP21 in 2015. During the decade, the company also reduced its CO2 emissions by 70%. Achieving carbon neutrality is not for the faint of heart and it’s all the more taxing if you have a multi-national presence, with a global manufacturing footprint and supply chain. We benefited from an early start, having recognized the need to check our emissions earlier in the decade. Still, we learned a lot on our path to carbon neutrality that can help others and speed their efforts. What follows are some nuggets of advice, hard-earned through experience. 1. Embrace systems change First off, success on emissions reductions is dependent on making it core to your strategy. This means drafting business goals that align with and can be accomplished through efforts to reduce emissions. Other steps are also key, including establishing science-based targets, dissecting every aspect of your operations to save energy and emissions, and investing in measurable, worthy projects that offset unavoidable carbon emissions. From the outset it’s important to involve teams from supply chain management, manufacturing, business travel, human resources, energy procurement and real estate, as decisions made by them will directly impact your carbon footprint. Leave no stone unturned. We broke down and reviewed energy use across all our operations. Then we set about transitioning to energy efficient technologies in our offices, manufacturing, and logistical sites. Naturally, installing our own energy efficient LED lighting was a no-brainer. But significant investment was made in energy efficient manufacturing technologies and more efficient HVAC […]
