GoodTextiles Foundation: Improving drinking water supply in Uganda

Together with Cotton made in Africa (CmiA) and the cotton company MMP Agro, the GoodTextiles Foundation is realising a project to improve the drinking water supply in Uganda, Africa. Bio-sand-waterfilters are being installed to gently purify the water from existing sources. In addition, the partners are training the community's farmers and craftsmen in how to operate the water filters. They then learn how to build new water filters.

In 2016, the textile company Dibella established the GoodTextiles Foundation with the aim of making textile value chains more sustainable. It raises donations and implements its own funding projects to benefit people at all stages of the textile industry.

As part of a joint project between the GoodTextiles Foundation, the Aid by Trade Foundation (AbTF) (owner of the CmiA standard) and MMP Agro, farmers who grow CmiA cotton in the districts of Abim, Kaplebyong, Dokolo and Kaberamaido in north-east Uganda are now receiving a total of around 1,000 bio-sand-waterfilters. Around 1,000 CmiA farmers, mainly women and the members of their households (an estimated 10,000 community members) benefit from this.

Artificial intelligence to help remove PFAS

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

PURE LOOP: High-strength synthetic nonwoven made with a recycled content of 10 percent

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.

EREMA Group acquires stake in start-up company plasticpreneur®

As of 30 May 2022, EREMA Group GmbH acquired 19.8 percent of plasticpreneur® gmbh. plasticpreneur® is an Austrian start-up company founded two years ago that manufactures at its production site in Klagenfurt recycling solutions for plastic waste that are mobile and can be operated without prior knowledge. The machine portfolio covers the recycling process and the production of new end-products. Due to it´s wide range of applications, it is in demand both in the Global South and in industrialised countries.

In the two years since the company was founded, plasticpreneur® has already sold 330 machines to customers in over 70 countries on all continents. In addition, they have made over 750 application-specific moulds, many of them custom-built to comply with individual customer specifications.

While plastics recycling has gained enormous momentum in the industrialised countries, more remote and poorer regions of the world have hardly benefited from high-tech solutions for industrial recycling processes so far. They are held back by a lack of infrastructure and know-how. That is why waste is often incinerated or disposed of in landfills, rivers and the surrounding environment. "Our mission - Another life for plastic, because we care - is also aimed at supporting these regions with solutions for plastic recycling, and with plasticpreneur® we have found the ideal partner for this," says Manfred Hackl, CEO EREMA Group.

The start-up company's machines can process HDPE, PP, PS, LDPE, PLA, AB and TPU separately. Their product range includes a shredder, injection moulding unit, extruder unit for the production of end products, air filters as well as custom-built moulds. "For our machines to be used in regions with little infrastructure, they must be easy to operate without prior knowledge. The fact that we also develop end-product solutions needed locally makes our range of services particularly attractive here," explains Sören Lex, CEO and co-founder of plasticpreneur®. As soon as recycling also becomes a source of income for the operators, they become entrepreneurs. That explains the name of the start-up, a word created from "plastic" and "entrepreneur". plasticpreneur® customers in these countries include e.g. social enterprises and operators of refugee camps, where everyday consumer goods - from clothes pegs and school supplies to toys and fence posts - are produced and sold using plastic waste. This means that the added value stays local.

The demand for plasticpreneur® machines is also increasing in industrialised countries. On the one hand by educational institutions and organisations that use them to raise awareness of the need for a circular economy in workshops and to give pupils as well as adults a better understanding of plastic recycling. On the other hand by customers who are developing new end-products for plastic waste together with plasticpreneur®. Because the machines are so easy to operate they enable a low-theshold use of recycled plastics in product development processes, starting from generating prototypes to launchin small series production. Small companies, product designers and developers therefore are another steadily growing customer segment.
