Since the industrial revolution, the ocean has absorbed increased levels of carbon dioxide, leading to the ocean’s pH becoming more acidic. Effects of these pH changes on marine and estuarine biota is the focus of much research effort worldwide and the authors of this study focus on the larval habitat-choice process of a commercially important tropical marine fish species, Lates calcarifer, barramundi.

New research has identified major drivers of food waste around the world. For example, in developing countries a lack of refrigeration technology is a major driver of food waste, and in the developed world low prices and increased choice encourage wasteful behaviour from consumers. Experts predict that drivers such as these will continue to increase food waste.

Europe produces around 450 million tonnes of construction and demolition waste every year, representing a quarter of all waste materials. A recent study of construction and demolition waste suggests that, with the right policies in place, there are good opportunities to ensure sustainable practices through re-use and recycling.

The challenge of measuring the ‘absence of waste’ makes it particularly difficult to monitor and evaluate waste prevention policies. Researchers have examined the strengths and weaknesses of nine methods of assessing waste prevention, and recommend a hybrid approach, which combines the best of many methods, as particularly valuable.

Over a third of all food waste in Sweden is avoidable, according to new research. If such waste minimisation were achieved, there would be less potential for biogas production, but the researchers suggest that this does not represent a compromise because it is currently performed on only a very small amount of waste food.

Increases in global energy requirements could lead to a rise in the energy sector's water footprint of up to 66% in the next 20 years, new research suggests. As part of a sustainable future, any energy mix must enable a reduction in greenhouse gas (GHG) emissions. However, some renewable sources, such as biofuels and large-scale hydropower, have large water footprints, a factor which must also be considered in energy policies, the researchers say.

The carbon footprint of food waste should be taken into account alongside the the weight of food wasted, says a new study. The research examined three years of food waste data from six branches of a Swedish supermarket and calculated the waste’s carbon footprint. On the basis of their footprint, key products that could be targeted for waste reduction include beef mince, meatballs and cream, the results suggest.

A new method of processing food waste into fertiliser has been outlined in a recent study. The process uses a digester system with microorganisms to break down organic waste into fertiliser. The resultant fertiliser was used in a low-energy greenhouse to produce a range of food crops. The method is a potential way to utilise food waste and reduce the energy consumption of food production as part of a circular economy.

The development of future recycling technologies must be informed by data about products and materials that will enter the waste stream, but such forecasts are subject to a high level of uncertainty. In this study, researchers have proposed a methodology for predicting emerging waste materials, applying it to silicon-based photovoltaic (PV) panels. The findings show that closed-loop recycling — when post-consumer waste is recycled to make new products — of PV panel materials could mitigate up to 0.2% of the annual environmental impact of Flanders1, Belgium, if suitable technology was developed.

Between 13% and 16% of waste electric and electronic equipment (WEEE), furniture and leisure goods disposed of at household waste collection centres are in excellent working condition and could be easily be prepared for re-use, finds a new study from Bavaria, Germany. Improvements to waste collection, storage and treatment practices to prevent damage to disposed items could free up a further 13%-29% of these waste streams for re-use. Notably, weatherproof storage for WEEE at collection points could have prevented up to 86% of the damage endured by the studied items.

Food packaging waste is currently under scrutiny. In the context of its Circular Economy Action Plan, the EU is addressing this through, among others, its Product Environmental Footprint (PEF) initiative , which aims to enhance the reliability of environmental claims — both in a business-to-consumer and in a business-to-business context. The initiative aims, therefore, to boost the market of green and circular products. However, a review of the methods available for assessing the environmental sustainability of packaging now highlights the difficulty of clearly characterising packaging's environmental impact. The study suggests a new, fully quantifiable framework that could help to standardise assessment methods and bring 'environmental footprint labelling' to fruition.

The EU-27 have committed to a strategic goal of developing an innovative economy based on biotechnology and renewable resources — a so-called ‘bioeconomy’. To achieve this, however, the EU must successfully mobilise resources such as residual biomass — or waste products from organic matter resources. A new study1 has quantified the potential of key residual biomass streams in the EU-27. The results show that residual biomass has a theoretical energy potential equivalent to the annual energy consumption of Italy and Belgium combined, with straw and forestry residues comprising the two most productive potential sources. The findings also reveal specific opportunities for regions including Paris (France) and Jaen (south-central Spain).

Sixty-four per cent of organizations in India and Europe invested in cloud technologies in the last two years, followed by IoT, where 51% firms made investments.

Traditional services also have some very strong propositions, like digital workplace, engineering services. Some of the demand for that is intact and it is only getting accelerated.

A thin layer of lighter coloured asphalt applied to road surfaces could significantly lower surface temperatures in hot urban areas, according to a recent study. This could make living conditions more comfortable and reduce the amount of energy needed to cool buildings.

Scientists have reviewed the potential for worldwide development of geothermal energy systems in old, unused mines. The technology is proven in many sites and could therefore help increase the share of renewable energy sources in the energy mix, offering sustainability and job creation, which may make mining operations more appealing to investors, communities and policymakers.

Researchers have shown that graphene paper can be used to construct flexible and rechargeable batteries, which may even perform better than non-flexible batteries. These might be used in a range of portable, bendable and rollable devices and could also help develop new energy generation technology, such as flexible solar cells.

Most modern societies depend on fossil fuels (oil, gas and coal) as sources of energy for development and growth. Switching to renewable energy sources, such as photovoltaic (PV) systems, is necessary for sustainable development in the future. A new study suggests that it is currently much more efficient to use fossil fuels to develop PV power plants than to combust the same amount of fossil fuels in conventional thermal power plants: thus the sooner PV systems are developed, the sooner society will reduce its reliance on fossil fuels.

Aeration technologies designed to help landfill waste break down faster need to be refined in order to reduce pollution, greenhouse gas emissions and the long-term costs associated with landfill. This is according to a recent review of landfill aeration, which outlines some of the different systems currently available and highlights the need for better monitoring and sharing of data.

Compared with traditional remediation techniques used to remediate brownfield sites, supporters of phytoremediation argue that it is cheaper and more environmentally-friendly. A new analysis has reviewed its strengths, weaknesses, opportunities and threats, and suggests it is well suited to cleaning up sites with low to medium levels of contamination.

A smartphone app has been designed to help shoppers choose more environmentally-friendly protein-rich products, namely meat, vegetarian alternatives, eggs and dairy products. The methods and data used to measure these products' lifecycle environmental impacts are presented in a recent study.

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.

‘Dye-sensitised solar cells’ (DSSCs) are an alternative to traditional silicon photovoltaic (PV) cells. They have a number of advantages over traditional PV solar cells, including greater flexibility and lower manufacturing cost, but they are less efficient at turning sunlight into electricity. Taking inspiration from nature, new research has doubled their efficiency using pine tree-shaped nanotubes.

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.

A new review examines the potential uses and scientific, technical and manufacturing problems facing ‘van der Waals heterostructures’ - an emerging science which uses building block-like nanomaterials. Van der Waals heterostructures are nanomaterials built by layering different materials, each one atom thick, on top of each other, to create materials with unique properties and uses.

A new study has found evidence for lung toxicity of different forms of ‘cellulose nanocrystals’ (CNCs) in mice. The study suggests that physical characteristics, such as length, of the CNC relates to the type of effect it has on the lung. These nanosized crystals, made from plant-derived materials, are increasingly being used in novel applications, such as cleaning up oil spills in water and flexible electronic displays, and consumer products, which raises concerns about their potential health impacts.

Wind energy will likely continue to play a leading role in reaching the EU’s renewable energy targets. However, in some areas wind turbines face social opposition based in large part on the visual impact of wind turbines in the landscape. A new study outlines a novel methodology to measure emotional response to wind turbine visuals, which may assist wind farm planners in gauging public acceptance.

A new screening tool to assess the potential seismic risks (earthquake activity) from deep geothermal energy projects has been outlined in a recent study. The tool provides categories of seismicity risk for projects, which are dependent on factors including geological aspects, as well as social concern and location in relation to urban areas.

Researchers have examined two cases of managed realignment in the UK, whereby coastal areas are deliberately flooded to recreate protective salt marshes. They demonstrated that a sequential decision support system (DSS) can be combined with an ecosystem services approach to provide a robust economic valuation of managed realignment’s benefits. For the case studies analysed, the benefits of managed realignment were found to outweigh costs in the long-term.

A new study has developed a system to assess the potential of ecosystems to supply ecosystem services in the EU-25 plus Switzerland and Norway. It is one of the first to use historical and projected data on land use change at a continental scale to estimate the provision of ecosystem services and to assess possible trade-offs between them.

Ecosystem services, such as coastal protection or water supply, form an integral part of ecosystem-based adaptation to climate change. However, preserving and restoring ecosystems and their services relies on the economic system that supports these efforts. Ecosystem services will not be best protected by the classic market framework, new research suggests.

Climate change will lead to an increased risk of flooding and huge economic losses if countries do not invest in appropriate adaptation measures, according to a new study. The research estimates the risks posed by flooding to cities around the world and the associated economic losses in 2005 and 2050, and suggests that flood protection must be increased to maintain the same level of risk to coastal cities.

In addition to reducing carbon emissions, policies promoting efficient energy use can encourage innovation in the manufacturing sector. This study evaluated the innovation effect of household energy policies using a comprehensive dataset of 21 European countries. The results show that policies such as financial subsidies and product labels can promote the development of sustainable-energy technologies.
