Researchers in Berlin have demonstrated that urban wasteland areas can be used as suitable habitats for a range of grassland species. Using simple and cost-effective measures to sow grassland seed mixtures, they found that such areas flourished despite poor soil conditions and high levels of impact from people.

Sustainable food production in developing countries can be achieved through ‘agroecology’ – where farming practices mimic nature rather than relying on external products, such as fertilisers and pesticides. This is according to a recent report, which claims that conventional farming does little to alleviate rural poverty and ecosystem degradation.

Producing and consuming food has a significant environmental impact. In the search for a sustainable diet, researchers in Sweden explored a method of food production that does not exceed the level of globally available arable land per capita, and involves raising livestock on pasture or by-products not suitable for humans (the ‘ecological leftovers’ principle). The researchers developed three diets based on this method and evaluated their environmental impact compared with current diets.

Risk analysis and technology assessment (RATA) involves assessing the possible human, environmental and societal risks of a novel technology at various stages of the development process. However, best practices for RATA’s successful incorporation into large-scale research programmes are still in development. In a recent study, researchers present a case study of their efforts to bring RATA into practice within a large Dutch nanotechnology consortium. By outlining the procedures and products they developed and reflecting on their experiences, the researchers provide valuable insights for the future integration of RATA in technology development projects. The findings are relevant to stakeholders with an interest in supporting the design of key enabling technologies, including governmental agencies and industrial partners.

Researchers have developed a methodology that allows the analysis of how an existing product design meets design guidelines required for the circular-economy perspective, and which guidelines would need to be incorporated to create a better circular-design product. The results, based on a case study of small electrical equipment in Spain, indicate that the most urgent priority is to incorporate circular-design guidelines related to extending life span and to product/components re-use, while there is a moderate need to include guidelines related to the use of simple removable connections or a modular product structure.

New research has investigated the many ways in which technological transfer occurs for wind power projects in developing countries. These range from trading with developed countries, to local innovation. In India and China, successful transfer was found to depend more on existing capabilities in these countries than international projects, such as the Clean Development Mechanism (CDM).

The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ecological considerations of micro-turbines.

The available and emerging renewable technologies suitable for urban environments have been assessed in a recent study. Wind and solar technology can now be integrated into building design, and smart grids and metering can more efficiently manage energy production and demand at a local level. Investing in community-level renewable-energy projects can, therefore, help meet the future energy needs of towns and cities.

A participatory approach to waste management has been tested in Naples, Italy, a city which has experienced ongoing problems with the collection of municipal waste.

A recent study has assessed some of the environmental impacts of the production of batteries used with low carbon systems, such as photovoltaic cells and wind turbines. The results indicate that lithium-based batteries have the most significant impact, in terms of metal depletion and greenhouse gas (GHG) emissions, but more complete data are needed on possible toxic impacts to conduct a full comparison between batteries.

Networks of wireless sensors could be used to monitor traffic noise. A new study shows that the wifi sensor systems, although slightly less accurate than precision noise monitoring systems, can provide detailed information, with dense coverage, about traffic noise over a longer period. Their low cost and low energy requirements make them particularly suitable and attractive for use by local authorities or even community groups.

A major environmental challenge for wastewater treatment is the disposal of excess sludge produced during the process. The LIFE Perbiof project has been developing and testing a technology that will help to overcome this challenge. Results demonstrate it can perform highly effective treatment of municipal wastewater (removing 80% of the organic content) while producing low levels of sludge.

Polarised light forms the basis of many technologies, such as computer monitors. However, current approaches for making polarised light are inefficient, as they produce more than is ultimately used or needed. Researchers may now have found a way to directly produce polarised light using tiny nanostructures, called quantum dots, opening the way for more energy-efficient technologies.

Researchers have summarised the most effective ways that nanostructures can improve the efficiency and lower costs of photovoltaic (PV) solar cells in a recent analysis. Sculpting ultra-thin solar cell surfaces at the nano-scale has been found to effectively boost their efficiency.

Power plants are a major source of CO2 emissions and contributor to global warming. This study reports on a portable technology to remove CO2 from their combustion exhaust gases. Pilot testing on a coal burning plant in Poland captured thousands of kilograms of CO2 per day. This could be a viable future means of mitigating CO2 emissions from the power generation sector.

Cool pavements, which can be used to reduce the Urban Heat Island (UHI) effect, where towns and cities are warmer than surrounding rural areas, have been reviewed in new research. The review found that reflective pavements can reduce temperatures by up to 20°C and are more durable than evaporative pavements, which are less effective at temperature reduction but may have other benefits, such as reducing runoff.

Priorities for future environmental technology research and development were outlined by a study that surveyed experts in the field in 2010-11. The global environmental problems and potential solutions that new technologies could provide were identified and discussed in questionnaires and workshops. One of the main recommendations of the study was for a greater focus on flexible and cost-effective innovations that could alleviate potential environmental issues in countries with developing and emerging economies.

‘Climate-smart agriculture’ aims to sustainably increase agricultural production and increase resilience to climate change. One aspect focuses on climate-smart technologies. This study interviewed users and producers of these technologies, highlighting barriers to adoption and possible means of overcoming them, including increasing awareness, user-focused design and changes to policy.

Environmental impacts for a wave energy device, tidal stream and tidal range plants are potentially eight, 20 and 115 times lower respectively than for coal-generated power, averaged over five impact categories. An assessment of the amount of metal used by these technologies, however, shows an impact respectively 11 and 17 times higher than for coal- and gas-based power generators. These are the findings of a recent study, which compared the life-cycle environmental impacts of various wave and tidal energy devices with other forms of energy generation. The researchers conclude that wave and tidal energy plants qualify as ‘green’ technologies according to their definition, but that their impacts on marine ecosystems need further research.

A new study provides clues as to which innovative low-carbon technologies will successfully get onto the market quickly. The historical analysis of 16 energy technologies — from steam engines to wind power — found that the average length of a product’s ‘formative phase’ is 22 years. This important period of innovation in a technology’s development is shorter for products which do not need extensive new infrastructure or changes to user behaviour. The findings could help policymakers identify new technologies that can be deployed more rapidly to meet short-term environmental targets.

Indium, a unique metal, is in short supply worldwide and is not recycled at the end of its life (EoL). Indium is used in a wide range of technologies, causing regions across the world that are reliant on its import — such as Europe — to be concerned about security of supply. Primary sources of indium are thought to be sufficient for medium-term needs, but with growing demand comes growing concern over long-term supply. A new study has conducted a material flow analysis and examined secondary sources of indium within European ‘urban mines’ and in-use stocks (IUS) of indium products, identifying these as potential sources of 500 tonnes of indium — if it were recycled at EoL.

A new study explores how to weigh up the costs and benefits of technologies that extract phosphorus from livestock waste for re-use as fertiliser. Findings from a US case study suggest that recycling phosphorus in this way can cut both water pollution levels and the costs of cleaning up the mineral. However, the technologies’ long-term economic feasibility depends on the yield, quality, and market value of the recovered phosphorus.

Researchers use life-cycle assessment (LCA) as a tool to evaluate the environmental impact of products and technologies across their entire lifetime — from extraction of raw material to end-of-life (disposal or recycling). It is challenging to apply the conventional LCA method to new or emerging technologies, however, due to the sheer quantity of data needed for such studies. This study proposes a screening-to-LCA method that uses available data to systematically evaluate the performance of such technologies, and support the uptake of those that are most environmentally sustainable.

The economic costs of replacing energy inefficient high-pressure mercury (HPM) lamps, used in outdoor lighting, with more efficient alternatives have been explored in a recent study. High-pressure sodium (HPS) lamps would be more cost effective than light-emitting-diode (LED) technology, although the researchers say LEDs could become more economical in the future.

A tax of €0.05–0.27 per kilogram (kg) of fertiliser could help to limit French farmers’ use of fertiliser, which is driven by the high rapeseed prices resulting from biofuels policy, according to new economics research. This, in turn, may limit fertilisers’ environmental impacts, such as water pollution, the study’s authors suggest.
