Smart Low-Tech Designs: Improving harvest yield and storage
Posted in Models, Research by Kate Archdeacon on January 11th, 2012
This week Nourishing the Planet TV showcases some of the work that Compatible Technology International is doing to help farmers preserve or process their crops to reduce loss:
“In its effort to alleviate poverty and hunger in the developing world, Compatible Technology International (CTI) designs, builds, and distributes affordable post-harvest tools—such as a cool storage shed and food processing grinder—for rural farmers in the developing world. CTI’s devices can help farmers process, store, and sell their crops.
While many organizations are focused on improved seeds, access to fertilizers, and irrigation to improve crop yields, relatively few are focused on post-harvest improvements. But many poor farmers live on yields from a hectare or less of land and getting the maximum benefit from those yields can make up the difference between abject poverty and a livable income.
CTI’s technologies are scaled to fit the needs of small villages, families, coops, and micro-businesses. Extra attention is paid to developing safe, affordable, environmentally friendly, energy-efficient, and culturally compatible devices in the hope that they will be more widely adopted and facilitate lasting change in poor farming communities. CTI encourages craftsmen and entrepreneurs in and around these communities to build and sell their devices, reducing dependence on outside assistance once the technology has been adopted.” Matt Styslinger

Diverting waste to make durable products: Replas on Kangaroo Island
Posted in Movements by Kate Archdeacon on December 19th, 2011
From the Re-Plas blog:
Not only was Kangaroo Island, in South Australia, one of the first locations in Australia to ban the use of plastic bags, but now the KI Council has gone a step further in helping the planet by installing 27 outdoor settings, 900 bollards and a staircase, all made from recycled plastic.
Ian Woolard, Co-ordinator Civil Works, Kangaroo Island Council, said, ‘We were looking for a product that would stand up the elements experienced on the South coast of Kangaroo Island and one that would incur the minimum ongoing maintenance cost to Council’. As a result of choosing to use recycled plastic KI council has diverted approx. 22,000 kg of plastic waste from landfill in 2010-11 alone.
Six years ago Kangaroo Island started the trend by purchasing recycled plastic seats for their school. More recently the local Landcare Group built a staircase out of garden panels and the Kingscote Jetty was also refurbished with Enduroplank™ decking as part of a trail by the South Australian government to see if recycled plastic proves more durable and cost effective than timber. All of this adds up to an estimated 35 000 kg of plastic waste which has been diverted from landfill and made into Replas recycled-plastic products for use throughout Kangaroo Island. Not bad for an island with a population of 4500!

Food Waste & Blaming the Individual: Research Article

From “Attitudes to and behaviours around food waste“:
This paper is written by David Evans of the Sustainable Consumption Institute. It is based on observations of ‘ordinary’ people shopping for and preparing food (19 households in all). It argues that, contrary to the prevailing view, people do know how to cook and do care about throwing food away. However it argues that the pressure to ‘eat properly’, in part a consequence of the styles promoted by celebrity chefs, gives rise to food purchasing habits that are unrealistic and give rise to waste. It concludes by suggesting ways in which food waste can be reduced – by portion resizing and by moves to “normalise the provisioning of foodstuffs that are not susceptible to rapid decay” (ie. tins, dried foods, frozen foods etc).
Reference and abstract as follows:

DOI:10.1080/09581596.2011.608797
In public debates about the volume of food that is currently wasted by UK households, there exists a tendency to blame the consumer or individualise responsibilities for affecting change. Drawing on ethnographic examples, this article explores the dynamics of domestic food practices and considers their consequences in terms of waste. Discussions are structured around the following themes: (1) feeding the family; (2) eating ‘properly’; (3) the materiality of ‘proper’ food and its intersections with the socio-temporal demands of everyday life and (4) anxieties surrounding food safety and storage. Particular attention is paid to the role of public health interventions in shaping the contexts through which food is at risk of wastage. Taken together, I argue that household food waste cannot be conceptualised as a problem of individual consumer behaviour and suggest that policies and interventions might usefully be targeted at the social and material conditions in which food is provisioned.

Design for Repair: Teakettle Craft Project

From A Series Of Teakettles, Merges Craft and Mass Production by Belinda Lanks:
Like so many generic office towers, electric teakettles (standard in European households) soak up precious real estate without offering the slightest bit of aesthetic value. The Parisian designer Jean-Baptiste Fastrez wants to change that, by creating one-of-a-kind teakettles, with the help of artisans and a few mass-produced parts. For his “Variations Upon a Teakettle” project, Fastrez merged the industrial and handmade, combining standard-issue electric parts, which meet safety and heat regulations, with beautiful, artisan-crafted vessels. In his words: “In opposition to the industrial ideal (an object for all) is a more human and sustainable production: something for everyone.” The project is a touch profound — demonstrating how craftspeople can still add lasting value, despite all the trappings of modern production.
—
If an electric teakettle can be assembled from off-the-shelf (OEM) heating elements as well as handmade vessels, then these separate components can be repaired or replaced if they are damaged or when the owner’s taste changes. That would be an enormous improvement on the current system, where mass-manufactured kettles are very difficult to repair and are usually thrown away. Kate A

Eco-Ideation Tool: Re-Thinking Product Design
Posted in Research, Tools by Kate Archdeacon on August 3rd, 2011

Bocken N M P, Allwood J M, Willey A R and King J M H (2011). ‘Development of an eco-ideation tool to identify stepwise greenhouse gas emissions reduction options for consumer goods’ Journal of Cleaner Production 19 1279-1287
Abstract
Pressure on consumer goods manufacturers to develop new products with significantly less environmental impact is growing, through increased consumer awareness of environmental issues and governments setting ambitious emissions reductions targets. A strategic response to this pressure is to prepare a portfolio of innovative product ideas to meet a range of future emissions reductions targets.However, although extensive work exists on ideation (the generation of novel product ideas) and ecodesign (design for reduced environmental impact), eco-ideation (generation of ideas that particularly aim to reduce environmental impacts) has had little attention.
The challenge of eco-ideation is to release the creativity of a broad range of employees, only few of whom may be familiar with the drivers of environmental impact. This paper proposes a novel tool to facilitate the generation of radical product and process ideas giving step-change reductions in greenhouse gas emissions. The features of products and processes that drive greenhouse gas emissions across the product life cycle were characterized with a set of indicators. A simple visual tool was created to show these indicators on a sliding scale between best and worst imaginable performance. A leading question associated with each slider was designed to stimulate lower impact ideas.
The tool was iteratively refined and simplified through structured testing with individuals from across a range of roles and differing knowledge of environmental impacts. The final eco-ideation tool used 14 scales, with leading questions for each scale developed to stimulate idea generation. The tool’s effectiveness was evaluated through use in a series of 15 individual workshops and compared with the outcomes of an equal number of conventional 12-person group-brainstorming sessions.
The comparison suggests that using the simple tool generally leads to a wider range of more radical ideas than emerge from group brainstorming.

Pros and Cons of Re-Manufacturing: MIT Energy Analysis
Posted in Research by Kate Archdeacon on May 24th, 2011
Source: Environmental Research Web
From “When is it worth remanufacturing?“:
It seems like a no-brainer: Remanufacturing products rather than making new ones from scratch – widely done with everything from retread tires to refilled inkjet cartridges to remanufactured engines – should save a lot of energy, right? Not so fast, says a new study by researchers at MIT. In some cases, the conventional wisdom is indeed correct. But out of 25 case studies on products in eight categories done by a team led by Professor of Mechanical Engineering Timothy Gutowski, there were just as many cases where remanufacturing actually cost more energy as cases where it saved energy. And for the majority of the items, the savings were negligible or the energy balance was too close to call.
Why are the new results so different from what might have been assumed? The MIT team looked at the total energy used over the lifetime of a product – a life-cycle analysis – rather than just the energy used in the manufacturing process itself. In virtually all cases, it costs less money and less energy to make a product from the recycled “core” – the reusable part of the product – than to start from scratch. But the catch is that many of these remanufactured products are less energy efficient, or newer versions are more energy efficient, so the extra energy used over their lifetime cancels out the savings from the manufacturing stage.
[...]
Gutowski emphasizes that this research does not necessarily suggest a specific course of action. For any given product, there may be other reasons for preferring the remanufactured version even if it produces a net energy penalty. For example, remanufacturing may reduce the burden on landfills, reduce use and disposal of some toxic materials, or produce needed jobs in a particular area. And the expanded use of cell phones may have important social benefits, such as contributing to the recent wave of revolutions in North Africa and the Middle East. “We’re not saying you shouldn’t do it,” he says – just suggesting that it’s worth understanding the decision’s effects in their entirety. “You think you’re doing the right thing, it sounds so simple,” Gutowski says. But when it comes to understanding the true impact of purchasing decisions on energy use, “things are far more complicated than we expect.”

Brisbane to Construct Second Landfill Gas Plant

From “Willawong waste-to-power plan gets Green approval” by Karin Adams, Sarah McVeigh on QUT News:
The Greens have welcomed Brisbane City Council’s plan to turn rubbish into power, but say the council is years behind the rest of the world.
The landfill site at Willawong in the south of Brisbane will have its methane and carbon dioxide emissions turned into electricity and put into the grid. Methane gas is 21 times more environmentally damaging than carbon dioxide. Landfill Gas Industries managing director Adam Bloomer, the company building the plant, says this will tackle a huge problem for council. “Every council in Australia that owns a landfill,” she said. “Their landfill is their single biggest source of their carbon emissions.” “Generally they’re somewhere in the range of 60 to 70 per cent of their greenhouse gas emission.”
Queensland Greens spokesperson Libby Connors says Brisbane and Australia are behind the rest of the world. “Queensland and Brisbane in particular are a long way behind the (Organisation for Economic Co-operation and Development) where at least 20 OECD countries are already using this sort of technology,” she said. She says she has been calling for the Willawong landfill gas plan for 20 years. “Australia has been really smug for many years that the easiest solution for our waste disposal is landfill because we’ve supposedly got all this space,” she said. “You know that is just completely been the wrong attitude.”
Waste Management Association of Australia Queensland president Pravin Menon says Brisbane City Council is pushing forward with good sustainability policy. “What Brisbane City Council is doing is extremely responsible from an environmental perspective…in actually utilising a resource in the ground that would otherwise add to our environmental impact,” he said. He says future waste management strategies need to avoid, reuse and divert waste. “Councils should firstly look at reducing the amount of waste that they send to landfill,” he said.
Ms Connors says Queensland is missing landfill gas plant opportunities. “It’s interesting the only two plants are here in Brisbane but there are plenty of other opportunities to develop this around the state,” she said. Mr Bloomer says the benefits of the plant are environmental but won’t stem the rising electricity prices. “I don’t think it’s going to make a big difference to electricity prices,” he said. “Renewable energy is still a premium product as far as cost is concerned.” But he says what it will do is provide power to around 1400 homes annually. The plant will be operational by June 2012.

Learning from a Community Composting Setback
Posted in Movements, Opinion, Research by Kate Archdeacon on April 20th, 2011
From “Community composting – here one day, gone the next” by Russ Grayson:
“…A new technology or new approach to doing something had a greater chance of long-term success when it comes as a package containing the technology + a clear plan for its maintenance + the training of those who will take over and use it.”
What had started as an innovative idea of local people came to an end when, one warm Wednesday afternoon in late March 2011, the City of Sydney removed the community composting installation in Peace Park, Chippendale. The removal reminded me of something I had learned some time ago at a place not very far away.
Technology transfer: a three-legged construction
In those days I worked for an international development NGO operating in the South Pacific and what I learned still makes a lot of sense to me. We worked in village food security and small scale, sustainable farming systems using the LEISA (Low External Input Sustainable Agriculture) approach, however the NGO—then based only hundreds of metres away in the University of Technology, Sydney, though 14 years in the past—also did village micro-hydro electrification.
It would have been easy for the NGO to have come in to some Solomon Island village and install a micro-hydro system, turn on the lights and leave. That approach was not unknown when it came to development assistance work by government programs and even by small, community based NGOs. Instead, those in the NGO were savvy enough to know that technology transfer, to be done properly, comes as a three legged structure. That technology transfer structure is this: a new technology or new approach to doing something had a greater chance of long-term success when it comes as a package containing the technology + a clear plan for its maintenance + the training of those who will take over and use it. It’s a simple enough proposition but it’s all too often ignored. The lesson has stayed with me and it came to mind when I started working with the City of Sydney where I collaborate with the City’s waste projects co-ordinator on community composting trials.
[...]
Gone, but a reboot is coming
Community composting is a new idea both to communities and to local government. Neither have tried it before. Solutions are being developed and trialled as we go. There are no instruction manuals. The City and local people installed a community composting system consisting of seven Aerobin composters (one for each day of the week) in Peace Park in inner urban Chippendale that is within easy walking distance of Sydney’s busy Railway Square.
That day in late March, the City in agreement with the local people who had been maintaining the system removed the seven Aerobins of the community composting facility. The reason? Cockroaches. Multitudes of cockroaches. The community compost had gone from a good idea in local resource recovery to a public health issue. There had been the comment from locals about odour and flies, though these may have been not the common house fly but vinegar flies and other flying insects that appear during composting as part of the decomposition process.
