A recent study has found that improved management of phosphorus in the EU would reduce reliance on imported phosphorus, in addition to reducing damage from excess phosphorus in the environment. This could be achieved through the appropriate use of fertilisers and greater recovery and recycling of phosphorus from all waste sources.

End-of-life-vehicles are a major stream of waste in the EU. A new study investigates the costs of landfill, advanced thermal treatment and incineration of waste from vehicle recycling factories and suggests that the factories are profitable, even while operating under strict conditions designed to meet the requirements of the EU’s Directive on End-of-Life vehicles.

Vast resources are required to extract speciality and difficult-to-recycle metals that are often only used once before disposal. Researchers argue in a new analysis that more must be done to improve metal recycling rates in order to secure our material needs for the future.

Sustainable management of phosphorus requires better information on how it flows through the environment via consumption and waste. New research from Sweden has found that 40% of phosphorus released by Gothenburg to the environment is in sewage sludge and a further 40% is in incineration ash. This suggests that phosphorus could be recycled from solid waste as well as from wastewater.

A new tool to improve the measurement of waste management performance has been presented by a recent study. The researchers applied it to three high consuming cities aspiring to ‘zero waste’, finding San Francisco to be closer to achieving zero waste than Stockholm and Adelaide, due to its emphasis on reusing solid waste.

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.

Management of waste from construction and demolition sites is a major concern, particularly in urban areas where large volumes of materials are generated. A recent study on the construction and demolition waste (CDW) produced in Lisbon, Portugal, suggests that improved municipal collection systems are needed to reduce the amount of waste ending up in landfill or illegal disposal sites.

Eco-innovations which help prevent the production of waste are explored in a recent German study. It considers the drivers and barriers to the uptake of material efficiency measures in businesses, green procurement and product leasing schemes.

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 price of electrical and electronic equipment has risen by an average of 2.19% since the implementation of the Waste from Electrical and Electronic Equipment (WEEE) Directive, new research suggests. Researchers investigated products across 27 EU Member States, with the increases in price reflecting the fact that the consumer is bearing at least part of the cost of e-waste disposal.

To solve the problem of food waste we need to radically rethink how our food is produced and consumed, researchers argue in a recent study. They propose a new framework that considers how to reduce wastage throughout the supply chain. Preventing excess levels of food production and consumption in the first place is its most important step.

Littering on coasts could be reduced by providing environmental information to temporary residents, research suggests. The study found that temporary residents were just as likely to litter as permanent resident populations and other visitors, but tended to be the group least aware of local environmental programmes.

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.

Researchers have designed and proposed a new organic waste management plan for Catalonia, Spain, and presented it in a recent study. They say that the plan would reduce a number of environmental impacts that arise from landfilling biodegradable waste, including natural resource depletion, acidification, and eutrophication.

Mining metals from landfill sites can be economically viable, a recent project in the US has demonstrated. Approximately 34 352 tonnes of metals, conservatively valued at US$7.42 million (€6.67 million) were recovered from the 8 hectare ashfill site, according to researchers who analysed the project.

Sustainable urban waste management has progressed over recent decades, with recycling of waste becoming a routine activity across the EU. However, the increasing volume and complexity of waste poses ongoing challenges for policymakers and municipal administrators. New research suggests that a rethink around how household waste is sorted could lead to more resources being recovered from solid waste.

Oysters exposed to polystyrene microplastics produced fewer offspring, which were also smaller and slower growing than offspring from unexposed oysters, according to recent research. The researchers say their study adds to growing evidence of the harm caused by microplastic pollution and can help stakeholders to take action on plastic debris entering the oceans to limit its long-term impact on marine life.

A US-based study has confirmed the prominent position that recycling and personal waste management take in the public consciousness. Crucially, the researchers suggest that understanding the popularity of such waste- management activities could help policymakers promote other forms of pro-environmental behaviour.

Around 50% of gold in used mobile phones is not recovered for future use, a new study finds. The researchers suggest that a global circular economy in mobile phones could be created by improving recycling of precious metals in phones in developing countries, as well as increasing the lifespan of phones and improving collection after use. These changes will reduce pressures on non-renewable resources and close ‘metal flow loops’.

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. This study tested a toolkit, which uses stakeholder engagement to improve waste-management decision-making. Residents and other stakeholders supported the use of a technological innovation to develop biomass fuel from municipal waste.

Analysis of the operation of a novel, micro-scale anaerobic digester has shown that this technology could provide a useful means of processing food waste in urban areas. The study found that the digester, located in London and fed mainly with local food waste, avoided 3.9 tonnes of greenhouse gas emissions, while providing biogas for cooking, heat and power. Anaerobic digestion on this scale could play a part in reducing the amount of food waste that goes to landfill1 and contribute to the circular economy.

Scientists have tested the behaviour of biodegradable plastics in managed composting and anaerobic conditions, as well as under simulated environmental conditions, such as in seawater or soil. This study found that blending different types of biodegradable plastics may open up new opportunities in relation to their end-of-life treatment — notably the potential to make one of the world’s best-selling biodegradable plastics, polyactic acid (PLA), home-compostable by blending it with another polymer (polycaprolactone — PCL). However, the researchers were also concerned that most materials tested could still cause plastic pollution as they failed to biodegrade sufficiently — and, in some cases, not at all, in particular, in soil and the marine environment.

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.

Adding compost to compacted urban soils can provide a lasting effect that aids tree growth, new research indicates. Urban soils improved with added organic material are less compacted after five years compared with soils that have not been treated with organic composts, the study suggests.

How best to integrate the ecosystem services concept into regional planning? A recent study provides a practical example for an area in Germany that is faced with an increased risk of soil erosion under climate change. Researchers used a decision-support system incorporating ecosystem services to show that measures to reduce soil losses could also support a number of other services.

The decline of urban populations and abandonment of buildings and land could provide an opportunity to promote ecosystem services, a new study suggests. The researchers examined the relationships between the use of abandoned land and ecosystem services, providing insight into the pros and cons of different urban planning policies.

Green walls, designed so they are covered in vegetation, could help cut the amount of noise that enters buildings, a new study has found. In lab. tests, researchers found that a modular green wall system reduced sound levels by 15 decibels (dB). This leads them to believe that it is a promising sound reduction device that could improve quality-of-life for city residents.

City children who spend lots of time in green spaces, such as parks, and at the beach are less likely to have emotional and social difficulties, indicates new research from Barcelona. The study of over 2000 children supports theories that green and blue infrastructure have benefits for our health and wellbeing.

Doctors prescribe fewer antidepressants in urban areas with more trees on the street, according to recent UK research. The study examined the link between mental health and wellbeing and the presence of trees in London neighbourhoods. Its findings support the idea that maintaining a link to nature, even in an urban area, may help provide a healthy living environment.

Simple characteristics of plant species - such as height or leaf size - can be used to predict the ecosystem services provided by the green roofs they grow on, a new study suggests. The researchers suggest that their method could be used to screen the thousands of potential plant species in order to optimize green roof design.

Green roofs have been proposed to mitigate flooding in urban areas. This study combined field experiments and numerical simulations to investigate the ability of green roofs to absorb rainwater. The authors describe how green roofs can be most effective at mitigating flooding, providing findings which will be important for policy on green infrastructure.

India saw a 62 per cent decline in job hiring in the month of April, led by hotel/restaurant/travel/airlines industries that saw a massive -90 per cent less hiring activity that the same month last year.

NITES, said that this went against the government guidelines of not firing people or cutting salaries during the pandemic.

An EU project has developed a new crop spray system for orchards that is precise, efficient and safer for the environment. It sprays pesticides according to the needs of the crop and local environment, and can reduce spray drift by up to 80 per cent. Preliminary field tests conducted in Poland have demonstrated its effectiveness.

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.

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.

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.

Which types of buildings will require the least energy for heating and cooling under climate change? A study in Vienna, Austria, looked at the balance between heating and cooling demand in four different types of buildings. The research provides a method that could be useful for other European cities trying to adapt to climate change.

Using vegetable waste to produce bioplastics can provide sustainable alternatives to non-biodegradable plastic, new research has found. The biodegradable plastic developed for this study, produced using parsley and spinach stems, cocoa pod husks and rice hulls, have a range of mechanical properties comparable to conventional plastics which are used for products from carrier bags to kitchenware and computer components.

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.

Desktop three-dimensional (3D) printers, available for use in offices and homes, can release between 20 and 200 billion ultra-fine particles (UFPs) per minute, finds new research. UFPs may pose a risk to health, and the study’s authors recommend caution when operating 3D printers inside unventilated or unfiltered indoor environments.

A nanoscale 3D printing technique could be useful for nanomanufacturing processes with environmental applications. The authors of a new study have found a way to control their printing process by incorporating a simple pattern into the printing surface. They say their technique could reduce costs for nanoscale printing.

A new tool for flood simulation and visualisation is accessible for both experts and practitioners, allowing them to collaborate better on flood planning and relief. Among other features, the new system includes 3D simulations, rainfall simulation and water flow data.

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.

Satellite images can provide important evidence of environmental crime, according to a UK researcher. Satellites are now able to take near-photographic pictures of objects on Earth as small as 0.3 metres which means that individual trees, cars and industrial pipes, for example, can be monitored from space.
