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.

A successful circular economy for valuable metals needs more than just effective recycling technologies, as a new study shows. The research, which explored the governance of recovering vanadium from steel-industry waste, revealed that industry stakeholders feel the prospect of financial gain, or reduced costs, through recovery is too distant at present. This perception could hinder a circular economy for critical materials from industrial residue, the study warns.

The potential of recycling aluminium scrap in Austria has been modelled in a new study. A surplus of mixed aluminium scrap is expected by 2045 if no advanced sorting technologies are applied. Increased demand for wrought aluminium alloys could mean this surplus occurs sooner. New methods to intensively sort aluminium could prevent this excess and contribute towards REACH1 recycling and climate targets.

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.

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.

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).

Researchers have devised a blueprint to integrate the efficient use of waste wood throughout a bioeconomy system — part of the economy that uses renewable biological resources from land and sea. This study assessed the environmental sustainability of three scenarios for increasing targeted levels of industrial symbiosis within the wood-based bioeconomy of central Germany, and found that, in most cases, the three alternative future bioeconomy networks outperformed the selected fossil-based reference systems, mitigating environmental impacts by 25 to 130%.

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.

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.

As Indian firms realign their focus on revenue growth, they need to leverage customer and market behaviour to place their bets on long-term, sustainable growth, a new report said.

The headcount has now come down from more than 1,000 employees a year ago, with the majority of job cuts in the wake of Covid-19 outbreak that forced shutdowns in the February-April period. The headcount comprises staff on the company’s rolls as well as those on contract and outsourced manpower.

Researchers have found that natural materials, such as plant fibres or wool, can be used to construct sustainable sound absorbers that help prevent noise pollution, which are as effective as conventional absorbers made from combinations of minerals and plastics.

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.

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.

Monitored natural attenuation (MNA) is a long-term, ‘hands-off’ approach to cleaning up contaminated land. New research has surveyed the current development of MNA in Europe and demonstrates a clear need for practitioners to systematically collect and learn from each other’s experiences with this form of brownfield remediation.

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.

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 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 is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical recommendations.

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.

A new study lists 10 factors to help create a closed-loop supply chain for critical materials. However, interviews with key actors in supply chains for photovoltaic (PV) panels and wind turbines suggest that manufacturers and recyclers hold different perspectives on these factors. The research highlights the importance of cooperation between supply-chain actors, as well as investment in technologies and infrastructure for closed-loop supply chains.

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.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

Payments for ecosystem services (PES) are one of a number of policy options available to support the provision of ecosystem services. Based on the characteristics of ecosystem services, a recent study has developed a framework for deciding when payments are a suitable tool for delivering ecosystem services.

Soils play a vital role in the Earth's life-support system, yet their importance and value to society is not always recognised. A recent study suggests that incorporating soils into a National Capital and Ecosystem Services framework will raise the profile of soils and enable soils to be more easily integrated into policy decisions.

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.

The mobility solution brings till to the consumer in the store and enables closure of the entire billing and payment process where consumers are.

The mobility solution has enabled the enrolment and agreement process online, followed with the customer’s digital signature and the receipt along with a confirmation SMS.

As electronics manufacturers are set to resume operations in India, it is apparent that in the short term there is no alternative to sourcing from China, as urgent replenishment of inventories clearly implies continued dependence on it.

April was a month of heavy-lifting for Anand Natarajan, COO, DBS Bank India, but the company’s investments made towards building a robust tech infrastructure made pandemic substantially easier for him.

New research on a major UK airport (Heathrow) has estimated that a night-time ban on flights could produce up to £860 million (1 billion euros) in financial savings over a 20 year period. Economic costs caused by the ban could be outweighed by savings from reduced health costs of sleep disturbance and stress caused by the noise of night flights.

The promotion of diesel-fuelled cars in Europe may not have had the beneficial environmental effects that were expected, research suggests. It has been assumed that they help reduce greenhouse gas (GHG) emissions from the transport sector, but studies show that their fuel efficiency is lower than previously believed, while their black carbon and nitrogen oxides emissions are higher. The consequent reduction in global warming effects from diesel cars may therefore be negligible, perhaps even negative.

Different European regions have very different diets and environmental conditions, meaning their water consumption varies widely. Despite this, switching to vegetarian diets in keeping with regional variation would substantially reduce water consumption in all areas, a new study concludes. Where people choose to eat meat, adopting a healthy diet low in oils and sugar will also reduce water consumption, although to a lesser degree.

Transport policies that produce physically segregated cycle lanes on main roads, combined with low-speed local streets, will boost numbers of cyclists and provide the best financial return on investment, new research suggests. Using Auckland, New Zealand as a case study the researchers showed that the economic benefits of this policy can outweigh the costs by more than 20 times.

TEvery kilometre travelled by car incurs costs to the individual and society that are more than six times those of travelling by bicycle, a new study suggests. The researchers presented a cost-benefit analysis developed for Copenhagen, finding that cars resulted in costs of 0.50 €/km in comparison to 0.08 €/km for bikes.
