GENEVA, Switzerland, October 9, 2018 ((Maximpact.com News) – Due to the growing volume of plastic waste now being produced and the plastic waste import ban imposed by China on December 31, 2017, plastic wastes, primarily from Europe, Japan, and North America, are now adrift on the global market. They have been arriving in the ports of countries such as Thailand, Malaysia, Vietnam, and Indonesia in alarming amounts.

The plastic scrap is often contaminated and mixed in ways that makes it difficult or impossible to recycle, so it ends up being dumped or burned openly in the recipient countries, creating toxic emissions and terrestrial and marine pollution.

In the first five months of 2018, Thailand had already seized 30,000 container loads of plastic scrap in their ports and was forced to impose an emergency import ban.

Governments worldwide are struggling with an avalanche of waste and coming up with solutions, large and small.

The most recent meeting of the world’s only international treaty on waste control ended with expressions of widespread and growing support for a proposal by Norway to add plastics to the list of wastes subject to the trade controls under the treaty, known as the Basel Convention.

The proposal, made at a September meeting in Geneva, is seen as a key mechanism to stem the tide of marine debris and plastic litter. It would add plastic waste to the list of wastes that require notification by exporting countries and consent by importing countries before export.

“Southeast Asia is already being hit hard by a tsunami of plastic waste,” said Von Hernandez, global coordinator of the Break Free from Plastic movement. “The Norwegian proposal to place plastic scrap under Basel controls will be a significant first step to protect Southeast Asia and developing countries everywhere from becoming the trash bins of the developed world.”

Many countries voiced their support for the Norwegian proposal on the floor of the meeting, including: China, Congo, Democratic Republic of Congo, El Salvador, Ghana, Indonesia, Kenya, Libya, Maldives, Malaysia, Namibia, Niger, Nigeria, Panama, Senegal, South Africa, State of Palestine, Switzerland, Togo, Tunisia, and Uruguay.

While there was broad support for the proposal, Canada, Japan, Australia and the European Union are seeking to block, delay or water down the proposal.

“The severity of the plastic pollution problem and its impacts on human health and the environment are undeniable and require urgent action. We cannot let a few countries or industry sectors prevent much-needed and in fact overdue action from the global community,” says David Azoulay, senior attorney for the Center for International Environmental Law.

The meeting also recommended the creation of a multi-stakeholder global partnership on the minimization of plastic waste. Both proposals – partnership and trade control – will go to the 14th Conference of the Parties of the Basel Convention for a decision in April 2019.

“The Basel Convention is uniquely positioned to take a leadership role in stemming the flood tide of plastic waste now engulfing the entire planet,” said Jim Puckett, director of the Basel Action Network, based in Seattle, Washington.

“They can do this not only by controlling unwanted trade, but by promoting steps to minimize the production of single-use and other unsustainable plastic products,” said Puckett. “We are thrilled that this week’s meeting has clearly signaled a turning of the tide.”

Cleaning the Oceans of Plastic Waste

To help cleanse the world’s oceans of the tons of plastic waste that have gathered in swirling gyres, the VTT Technical Research Centre of Finland has developed a mobile container unit called PlastBug. The unit acts to remove plastics from the water and treat them with microbes to turn them into useable chemicals.

“Our idea is to design a mobile container where microbes degrade plastic waste to valuable products like fuels or chemicals,” says Kari Koivuranta, principal scientist at VTT.

The small, container-based factories could be placed in areas where centralized plastic waste collecting or recycling is not possible. The container factories could be located on a beach or ship.

The factory units would get most of the energy needed for the process from solar energy and wind power.

The goal is for the pilot unit to operate on the Baltic Sea in 2021, but funding still needs to be secured for the realization of this plan.

Building With Waste Materials

A growing scarcity of resources, along with the desire to move away from today’s throwaway mentality, means that the building sector must give more thought to the multiple use and recyclability of materials, as well as to alternative methods of construction.

A residential module fully constructed from reusable, recyclable, and compostable materials is the premise for the newest unit in NEST, the modular research and innovation building run by the Swiss Federal Laboratories for Materials Science and Technology and the Swiss Federal Institute of Aquatic Science and Technology in Dübendorf.

On February 8, the NEST Urban Mining & Recycling unit opened its doors to house two students. At the same time, as an active lab, it is helping to advance the construction industry’s transition to a recycling economy.

The residence features structures and materials that can be fully reused, repurposed, recycled, or composted after deconstruction of the module.

The concept was designed by Werner Sobek with Dirk Hebel and Felix Heisel. Sobek is director of the Institute for Lightweight Structures and Conceptual Design at the University of Stuttgart.

Hebel is the director and Heisel is the head of research at the Chair of Sustainable Construction at Germany’s Karlsruhe Institute of Technology and the Future Cities Laboratory at the Singapore-ETH Center, established in 2010 by two Swiss government agencies that conduct high tech research.

“The ongoing, sustained growth of the global population as well as dwindling resources urgently require us to do some rethinking in the construction industry,” says Sobek. “In future, we must reduce our consumption of construction materials and build for many more people.”

So, the concept of cycles must play a central role on the path to more sustainable construction. “The materials that we utilize will not just be used and then disposed of; instead they will be extracted from their cycle and later returned to it,” Hebel explains.

Database for Urban Waste Miners

In one of the more sweeping solutions to the world’s waste problems, European organizations have united to create the world’s first database of valuable materials available for urban mining from scrap vehicles, spent batteries, waste electronic and electrical equipment, and mining wastes.

The Urban Mine Platform <urbanmineplatform.eu>, created by 17 partners in project ProSUM (Prospecting Secondary Raw Materials in the Urban Mine and Mining Wastes), presents the flows of precious and base metals and critical raw materials in products in use and throughout their journey to end of life.

The database reveals the amount of valuable materials recovered or lost in the EU’s scrap vehicles, batteries, computers, phones, devices, appliances and other high tech products discarded annually – roughly 18 million tonnes in all.

The ProSUM consortium says urban mining to recover valuable critical raw materials from wastes is vital for securing ongoing supplies for manufacturing and to limit dependence on non-EU suppliers.

This platform displays all readily available data on products put on the market, stocks, composition and waste flows for electrical and electronic equipment, vehicles and batteries for all EU 28 Member States plus Switzerland and Norway. Iceland is also included for vehicles.

The EU, Norway and Switzerland generated some 10.5 million tonnes of waste electrical and electronic equipment in 2016 – about 23 percent of the world total. In addition, two million tonnes of batteries and some seven to eight million tonnes of EU vehicles reach their end-of-life each year.

All represent a rich source of secondary critical raw materials.

The recently published Global e-Waste Monitor reported that the world’s 44.7 metric tonnes of e-waste alone in 2016 contained €55 billion worth of precious metals and other high value materials.

The Urban Mine Platform contains data for elements and materials in high abundance in these waste products, mainly base metals, precious metals, and critical raw materials.

Dynamic charts on the Urban Mine Platform offer detailed data and market intelligence on The number and type of products placed on the market, in-stock, and generated as waste. The compositions of key components, materials and elements, such as aluminum, copper, gold or neodymium are given, in batteries, electronic and electrical equipment (EEE), and vehicles.

Pascal Leroy, secretary general of the WEEE Forum, a Brussels-based not-for-profit association and ProSUM project coordinator says, “Three years in the making, this consolidated database is the world’s first ‘one stop shop’ knowledge data platform on CRMs in waste products – easy to access, structured, comprehensive, peer-reviewed, up-to-date, impartial, broad in scope, standardized and harmonized, and verifiable.”
