From aquaculture to agriculture, waste recovery connects value chains

,
From sea to farmland, recovering value from by-products opens up new opportunities for agriculture and other industries. But circularity, an EU report stresses, requires collaboration throughout the value chain

Bulrush waste could help remove dyes from wastewater

,
Researchers at Doshisha University in Japan have developed a new product that puts plant waste to use and removes dyes from water. A new opportunity for the circular bioeconomy
Landfill emissions peak in winter and reach their lowest levels in summer. Occasional measurements may therefore underestimate annual releases. Photo: Eric Guinther, CC BY-SA 3.0Eric Guinther, CC BY-SA 3.0

Landfill methane emissions could be far higher than estimated

,
A study of two New Jersey landfills finds emissions five times higher than official figures. Cold weather and falling atmospheric pressure drive higher releases. Occasional measurements may miss emission peaks
Some viruses can help enhance the bioremediation of contaminated soil, which is one of the major global environmental challenges.

Uno studio australiano propone di sfruttare i virus batteriofagi per potenziare i batteri che degradano gli inquinanti, aprendo nuove prospettive per il biorisanamento del suolo

Compostable bioplastic residues do not accumulate in soil

,
An international study fills one of the major scientific knowledge gaps surrounding compostable bioplastics. Any microfragments that may remain after industrial composting do not persist in the soil but continue to biodegrade thanks to microbial activity

Through electrolysis we can neutralize (and enhance) soil contaminants

,
The Federal Institute of Technology in Zurich has developed an electrochemical method for breaking down contaminants, recovering harmless salt and other useful products for the chemical industry. This frees the soil from the presence of stable toxins

“The new Bioeconomy Strategy is a step forward for the EU’s economic future”

,
David Newman (European Bioeconomy Bureau): "The document acknowledges past mistakes and seeks to correct them, also to avoid missing the train of opportunities that bioeconomy offers". But some aspects are worrying, starting with the lack of market-pull mechanisms to stimulate industrial innovation

Bioeconomy: The EU Commission presents its new strategy

,
The document aims to increase the Union's competitiveness through the development of the various sectors of the bioeconomy, a meta-sector that is already worth 2,700 billion and employs over 17 million people (8% of total employment)

Microplastics and agricultural soils: a winter school in Rome

, ,
You can register until November 16 for the winter school organized in Rome by Università Cattolica — a two-day event (November 20–21) focused on understanding the impact of microplastics and exploring ways to address the issue.
