European industry maps  chemicals added to  Plastics

A list of chemicals and their uses will support risk assessments and circular economy plans

It has been a decade since Europe started a huge "no data, no market" program requiring the chemical industry to prove the safety of chemicals placed on the market in European Union countries.

The project has produced a treasure trove of information helping regulators to more effectively identify and control chemicals that cause concerns for human health or the environment as well as helping industry to build consumer confidence in the chemicals. But the European Chemicals Agency (ECHA) didn't stop there. The most recent project to make use of this wealth of new data targets the chemicals added to plastics.

Chemicals that were once dismissed as eternally trapped in a plastic matrix have raised concerns in recent years about whether they can migrate into our food or bodies, where they end up when plastic products reach the end of their often-too-short lives, as well as how they impact hopes for a circular economy. So the ECHAmined their new database to identify all of the chemicals which had been registered by industry as plastic additives.

The ECHA handed this list over to industry associations, which worked to ensure correct information on the uses of chemicals in plastics is available. Maggie Saykali of the European Chemical Industry Council reflects on how much was learned during this exercise: “It was clear from the start of the project that we needed all project partners to use the same terminology for uses of plastic additives." But in the end it proved worthwhile, again in the words of Ms. Saykali:

"This project clearly demonstrates the value of a collaborative approach. ECHA provided an overview of substances registered under REACH, industry provided the knowledge of their uses and behavior, and academic experts helped develop a model to estimate release potential."

The reinforcement of the communication channels between suppliers and users of plastic additives will also help as plans for a circular economy for plastics proceed. The additives pose one of the major obstacles to the up-cycling of plastics. An agile and responsive supply chain is a key asset for evaluating changes that can favor better recyclability of plastics back into high-value products.

An overview of the results of the mapping exercise for plastics additives has been made public by ECHA, offering consumers interesting insights to what chemicals are in which plastics. Even more data remains in the hands of the regulators of the EU Member States, who take the lead in identifying the chemicals of concern. The model for predicting potential release will also inform decisions about how to prioritize risk assessments for these chemicals.

This plastic additive mapping exercise offers another great example of the value of putting the burden on industry to share information about the chemicals they use in the interest of better protection of public health and the environment. And it is a further step in helping the industry to build trust for the chemicals that provide benefits while eliminating the use of chemicals that don't merit that trust.

7 eating habits that we know are good for us:

1. Eat plenty of vegetables and fruits – Some countries are very specific about the number of servings of fruits and vegetables that we should consume daily, for example Greece says six, Costa Rica and Iceland say five. Canada even specifies the colors of vegetables to consume (one dark green and one orange vegetable a day). Serving sizes can vary by country; however, all guidelines recommend eating plenty of fresh vegetables and fruits on a daily basis.

2. Watch your intake of fats– Said in different ways, most guidelines make mention of reducing solid, saturated fats and give recommendations for replacing animal fats with vegetable oils. In Greece, olive oil is recommended, in Viet Nam it is sesame or peanut oil – demonstrating the importance of availability and cultural preference in each country’s guidelines.3. Cut back on foods and beverages high in sugar – It is generally agreed upon that processed sugar is harmful to our health. The guidelines in every country recommend to maint…

Humans are a massive minority on Earth. Why don't we act like it?

Humans are a massive minority on Earth. Why don't we act like it?

Most of us, including scientists, are blind to the full scope of the living world. This was illustrated by an informal survey which asked biologists and ecologists from elite universities two questions. In terms of mass, is the living world mostly composed of animals, plants or bacteria? And is there more global biomass on land or in the oceans? The majority of them answered both questions incorrectly.In an age of unparalleled access to information, this is a glaring gap in our knowledge. We are now equipped to close it. I joined colleagues from the Weizmann Institute in Israel and the California Institute of Technology to estimate the biomass of all kingdoms of life on Earth. The results were published in the journal of the American National Academy of Sciences, and were widely (and more digestibly) covered by the popular press.It required years of work, collecting and integrating information from hundreds of previ…

Chart of the day: These countries create most of the world’s CO2 emissions

With CO2 levels on the rise, being able to track global emissions is crucial. Image: REUTERS/Regis Duvignau Just two countries, China and the US, are responsible for more than 40% of the world’s CO2 emissions. With CO2 levels still on the rise, being able to track the global emissions hotspots is becoming more important than ever. Before the industrial revolution, levels of atmospheric CO2 were around 280 parts per million (ppm). By 2013, that level had breached the 400ppm mark for the first time. On 3 June 2019 it stood at 414.40ppm. Fifteen countries are responsible for more than two thirds of global CO2 emissions. Image: Visual Capitalist There are huge disparities between the world’s top 15 CO2 emissions-generating countries. China creates almost double the emissions of second-placed US, which is in turn responsible for more than twice the level of third-placed India.
