Green engineering to develop low-cost dam

The dam’s frame consists of gabion cages: wire mesh baskets filled with sturdy columns of recycled concrete cylinders or rocks. Designed by a team from the University of the Philippines Diliman (UPD), the “Gaia dam” could control or prevent flooding from torrential rains on farms, along rivers and in coastal areas by minimising and re-routing the flow of water through storm runoff pathways. Its main structural frame consists of gabion cages: wire mesh baskets filled with sturdy columns of recycled concrete cylinders or rocks, which provide stability against the hydrostatic forces pushing through the dam. Like a miniature hydroelectric power plant, the Gaia dam could divert water into the powerhouse where turbines are installed, yet do so less expensively than the concrete dams that are usually used for this purpose. In addition, the dam is designed to release proprietary proteins and enzymes when water passes through its specialised core. Its proteins are designed to help crops absorb soil nutrients and minerals, while its enzymes would gradually dissolve the exoskeletons of insects and other pests that attack the crops, thereby acting as natural fertilizers and pesticides. Thus the Gaia dam has the potential to help in the production of organic crops. The UPD research team is now exploring the possibility of creating a spin-off company to produce the Gaia dam and is seeking partners to license its technology. Meanwhile, the team plans to further develop the technology and build prototypes for Filipino farms.

Singapore's precision engineering sector PIC

Singapore’s precision engineering sector expanded by 4% in 2014

AMIC, MTA2015 exhibitor, says national education programmes and collaboration with industry has paid off and helped boost manufacturing industry One of the key drivers of the Singapore economy, the manufacturing industry, contributes about 20 to 25 per cent of its Gross Domestic Product (GDP). Precision Engineering (PE) – the backbone of the industry – is applied in sectors from aerospace to medical, equipment building to oil & gas. From simple contract manufacturing in the early days, the Singapore precision engineering sector now provides integrated solutions from design to prototyping to production and even supply chain management. The sector recorded a growth of about four per cent in 2014. To further boost the PE industry, the Singapore government has collaborated with industry and academic partners to develop fresh talent, as well as enhance the knowledge and deep skillsets of the current work force. The Additive Manufacturing Innovation Centre (AMIC) and Centre for Digital & Precision Engineering (CDPE) at Nanyang Polytechnic (NYP) are two such academic partnerships with the Singapore Economic Development Board (EDB). Through government support and funding in the Continuing Education and Training (CET) and Pre-Employment Training (PET) national programmes – cumulatively S$128 million – NYP offers the Precision Engineering Mastercraftsman (PeMC) and National Precision Engineering Scholarship (NPES) programmes for both students and working professionals. These programmes involve hands-on work at the AMIC and CDPE across every stage of the precision engineering process, from design to production. With the advent of new technologies, students now have the opportunity to enhance their skills and knowledge of the latest precision engineering and manufacturing technology such as additive manufacturing or 3D printing, robotics and Industrie 4.0 applications. The AMIC and CDPE unveiled these advanced manufacturing technologies at an exclusive media tour today. “Advanced manufacturing technologies such as 3D printing or even the Industrial […]

MTA2015: Robotics Market Set to Grow at 12% Annually Over Next Two Years

SINGAPORE, Mar 04, 2015 The International Federation of Robotics states that demand for industrial robots will continue at an average annual growth rate of 12 per cent between 2015 and 2017. In Asia/Australia, robot sales are expected to increase by around an average of 16 per cent per year. The automotive and electronics industries will continue to see increasing investment in robots. Mr. Lim Say Leong, Assistant Vice President, Marketing of ABB, thinks that in a new era of robotics, collaboration between humans and robots will become a reality. MTA2015 caught up with Mr. Lim to learn more about future trends in automation technologies and robotics for the Asian manufacturing sector. ABB, a global leader in power and automation technologies, will be showcasing its robotics solutions at MTA2015. Robotics made simple Small parts assembly is leading the charge in human-robot collaboration, where humans and machines are starting to work right next to each other, with no need for cages and other protective equipment or barriers. Automation will become simpler and more user-friendly, such as modular plug-and-produce components that will enable people without extensive experience in robotics to programme and integrate a robot in the process. At ABB we believe very strongly in a “what you see is what you get” (WYSIWYG) programming interface, so it is possible – perhaps even expected – that visual apps as well as programming by teaching (rather than coding) will greatly enhance the ease of programming for the next generation. The tools that allow robots to interact with the world around them are also in development, such as advanced sensing and advanced gripping. In order to allow robots to do all the jobs that they are well suited for, they will need to develop more “human-like” abilities to find, identify and manipulate objects. When combined […]

Why it pays to join the circular economy

We all know that the current linear economic model is not sustainable. Materials are extracted, manufactured into products and then discarded into landfill – it’s a system that wastes valuable resources, causes environmental damage and will make it near impossible to satisfy the demands of the 3 billion new consumers in developing nations, who are expected to join the middle class by 2030. The concept of the circular economy is about decoupling growth from resource consumption – and maximising the positive environmental, economic and social effects. It’s about designing products so that they are easier to reuse or recycle, like Timberland’s Earthkeeper shoes. It’s about making sure that every product ingredient is biodegradable or fully recyclable, like the chemicals company that has replaced fossil-fuel feedstocks in their production methods. It’s about maximising useful product life by repairing or remanufacturing, like Caterpillar’s parts-refurbishing programme. The circular economy is about new business models that have shifted from selling products to selling services, such as the tyre company that offers a per-km tyre-leasing service. It is about eliminating waste from production, and making sure any waste is recovered as a valuable resource, whether it’s heat, slurry, nutrients, organic material, metal, salt – whatever. It’s about engaging your customers throughout the life cycle of the product, instead of the few minutes during which they make a purchase; and, ultimately, it’s about gaining competitive advantage. The scale of the competitive advantage is startling. Against a backdrop of resource prices that have more than doubled over the past 10-12 years, erasing the commodity-price decline of the 20th century, our material-saving potential is expected to reach around $1 trillion per year by 2025. The opportunity presented by the circular economy in Europe and the US pales into insignificance compared with what is at stake in developing nations, […]

Let’s not follow the others

Picture: Doug Green, Publisher, Asia Manufacturing News www.asiamanufacturingnewstoday.com If Peter Thiel, co- founder of PayPal and Palantir has it right the future needs to change. It’s easier to copy a model than to make something new. Doing what we already know how to do keeps on adding more of something familiar. And it is easier to do. Peter Thiel has a book out with Blake Masters, Zero to One. How about we just don’t keep on being a computer manufacturer amongst lots of other computer manufacturers and make something new? Because if we keep on being moderate and doing what we know amongst other similar companies – our competition – then sooner or later we, the competition, may not be around much longer because competition amongst equals brings with it company takeovers. Three computer manufacturers become two. Why not make something brand new instead of copying what others are doing? Can we think of something that hasn’t been made before and not have to bother having competition. Get it? In golf, we talk about our own authentic swing. That may be a swing not based on our golfing buddies, not copying anyone else to drive the ball down the fairway. Because 2014 is rapidly coming to an end I think this is a good subject for all of us to look at for 2015. A great opportunity to dream and plan what might be next for our company that no one else is doing. Imagine that! Get your company geniuses together and ask the question “How can our company make something new and not take the easy way by continuing to do just what we know?” One upon a time someone invented the paper clip. Then someone else made another model, round, not silver, but in colours. It was still […]

Hankook Delcam holds world’s biggest meeting for CAM users

Delcam’s South Korean joint venture, Hankook Delcam, held its 25th User Group Conference at the Hyundai Hotel in Kyeong-Ju on 26th and 27th September. The theme for this year’s meeting was ‘Big Jump Up’, a reference to the large increases in productivity being seen by companies adopting software and services from Hankook Delcam.

Used cigarette butts offer energy solution

A group of scientists from South Korea have converted used-cigarette butts into a high-performing material that could be integrated into computers, handheld devices, electrical vehicles and wind turbines to store energy. The researchers have demonstrated the material’s superior performance compared to commercially available carbon, graphene and carbon nanotubes. It is hoped the material can be used to coat the electrodes of supercapacitors—electrochemical components that can store extremely large amounts of electrical energy—whilst also offering a solution to the growing environmental problem caused by used-cigarette filters. It is estimated that as many as 5.6 trillion used-cigarettes, or 766?571 metric tons, are deposited into the environment worldwide every year. Co-author of the study Professor Jongheop Yi, from Seoul National University, said: “Our study has shown that used-cigarette filters can be transformed into a high-performing carbon-based material using a simple one step process, which simultaneously offers a green solution to meeting the energy demands of society. “Numerous countries are developing strict regulations to avoid the trillions of toxic and non-biodegradable used-cigarette filters that are disposed of into the environment each year—our method is just one way of achieving this.” Carbon is the most popular material that supercapacitors are composed of, due to its low cost, high surface area, high electrical conductivity and long term stability. Scientists around the world are currently working towards improving the characteristics of supercapacitors—such as energy density, power density and cycle stability—whilst also trying to reduce production costs. In their study, the researchers demonstrated that the cellulose acetate fibres that cigarette filters are mostly composed of could be transformed into a carbon-based material using a simple, one-step burning technique called pyrolysis. As a result of this burning process, the resulting carbon-based material contained a number of tiny pores, increasing its performance as a supercapacitive material. “A high-performing supercapacitor material […]
