Greece orders 8 Airbus H215 helicopters to combat forest fires

Airbus Helicopters has signed a contract with the Hellenic Ministry of Climate Crisis and Civil Protection for the purchase of 8 H215 helicopters (with an option for 2 additional aircraft) to support the combat of wildfires in the country following a tender conducted by the Project Preparation Facility of Growthfund (the National Fund of Greece) on behalf of the Ministry. This contract is supported by 2 European funds and aligns with the Ministry’s Aegis Programme aimed at enhancing the capabilities of the Civil Protection forces. The contract will be based on a “government owned contractor operated” (GO-CO) model for which Airbus Helicopters will be partnering with experienced H215 firefighting operators, Airtelis and SAF Hélicoptères, for the technical and operational support. 

“The signing of the contract for the purchase of new H215 helicopters represents an important step in our efforts to mitigate the devastating consequences of the climate crisis in our country,” said Panagiotis Stampoulidis, Deputy CEO of Growthfund, about the significance of the project. “This is the largest contract signed under the ‘Aegis’ National Programme to bolster the Civil Protection mechanism in Greece with modern equipment, and we are delighted that the Project Preparation Facility of Growthfund swiftly concluded this tender with transparency and efficiency.”

“Wildfires have burned on average 3 to 5 million square kilometres globally in recent years with significant environmental consequences. It is an honour to have been selected to support the combat, with our H215 helicopters, that Greek communities face every year,” said Bruno Even, CEO of Airbus Helicopters. “The H215 is used around the world for firefighting missions with its ability to drop more than 4 tonnes of water at a time. Relying on experienced operators, such as Airtelis and SAF Aerogroup, is exactly what the French Securité Civile does. Airbus Helicopters has been a long-standing provider of helicopters for essential missions in the country and together with our GO-CO partners, we are sure that the H215 will be a vital and reliable asset,” he added.

SAF Aerogroup specialises in complex helicopter operations like mountain rescue, air medical services, firefighting and humanitarian/logistic missions, demonstrated by their 2024 H215 RescEU deployment to Greece. The group also manages high-precision lifting, maintenance and pilot/technician training, offering comprehensive high-value air services to governmental and international organisations. Similarly, Airtelis, a French operator based in the South of France with over 60 years of experience stemming from its parent company RTE, has broadened its focus beyond power grid support to include emergency response, notably firefighting, for a wider range of national and international clients.  

Airbus Helicopters has been a long-standing partner in Greece since the early 2000s in both the civil and parapublic and military sectors. The Hellenic Fire Brigade operates 2 Super Pumas and the Hellenic Air Force operates 12 Super Pumas. The Super Puma ecosystem in the country will benefit from the support activities and training of technicians and pilots foreseen by the contract.

Mitsui Chemicals, Hagihara Industries Jointly Develop Technology for Homogenizing Viscosity of Heterogeneous Recycled Plastics

Mitsui Chemicals, Inc and Hagihara Industries Inc. today announced that they have carried out joint development for technology to homogenize the viscosity of recycled plastics, resulting in the successful demonstration of this technology.

Background to the joint development 

Due to inconsistent quality among plastic waste, recycled plastics made using that waste can exhibit heterogeneous viscosity, leading to issues such as lower yields and an inability to use the recycled plastics outside of low-quality applications. In an effort to resolve these issues, Hagihara Industries and Mitsui Chemicals decided to take in-line viscosity measurement technology jointly developed by Mitsui Chemicals and the Nagaoka University of Technology and fit it to recycled pellet extruders to pursue the joint development of technology for homogenizing viscosity.

 

Mitsui Chemicals is aiming to achieve ongoing growth driven by solutions to social issues – and with this goal in mind, the company is working to make both society and the environment more sustainable via a transition to a circular economy. These efforts have previously seen Mitsui Chemicals work with the Nagaoka University of Technology on developing viscosity homogenization technology that leverages tandem extrusion to control viscosity in recycled plastic, with the aid of in-line viscometers capable of measuring plastic waste viscosity in real time.

 

Meanwhile, Japan’s largest manufacturer of blue tarps, Hagihara Industries is aiming to help bring about a sustainable society. As part of this pursuit, 2021 saw the company launch a Japan-first project called ReVALUE+™, which uses discarded blue tarps as a raw material to produce new blue tarps through horizontal recycling. However, the fact that discarded tarps are mixed with contaminants and other companies’ products upon recovery has caused issues with the quality of the recycled goods, requiring limits on the proportion of recycled material used in horizontally recycled products.

 

Hagihara Industries is therefore aiming to improve the quality of recycled materials, which would in turn allow it to further increase the proportion of these materials in its products. To achieve this, the company is leveraging its production technology for industrial machinery to develop advanced cleaning technology and equipment, as well as granulation equipment with highly effective contaminant removal (i.e. advanced filtration) and technology for refining and improving resin viscosity.

 

Now, #MitsuiChemicals and #HagiharaIndustries have further developed this technology to create a method wherein viscosity can be homogenized using only a single extruder. The companies hope that this will lead to the popularization of high-quality material recycling and, in turn, progress toward a circular economy.

Study shows okra and fenugreek extracts can remove microplastics from water

The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer. Previously, researchers proposed using these sticky natural polymers to clean up water.

Now, they report in ACS Omega that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics in ocean water, freshwater & groundwater.

Rajani Srinivasan and colleagues have been exploring nontoxic, plant-based approaches to attract and remove contaminants from water. In one set of lab experiments, they found that polymers from okra, fenugreek & tamarind stick to microplastics, clumping together,sinking for easy separation from water.

Also spoke about successful demonstrations of the plant extracts in freshwater and ocean water at ACS Spring 2022, a meeting of the American Chemical Society. In this next stage of the research, they have optimized the process for okra and fenugreek extracts in various types of water. 

To extract the sticky plant polymers, the team soaked sliced okra pods and blended fenugreek seeds in separate containers of water overnight. Then, researchers removed the dissolved extracts from each solution & dried them into powders. Analyses showed that the powdered extracts contained polysaccharides, which are natural polymers. Initial tests in pure water spiked with microplastics showed that:

One gram of either powder in a quart (1 liter) of water trapped microplastics the most effectively. 

Dried okra and fenugreek extracts removed 67% and 93%, respectively, of the plastic in an hour. 

A mixture of equal parts okra & fenugreek powder reached maximum removal efficiency (70%) within 30 minutes. 

The natural polymers performed significantly better than the synthetic, commercially available polyacrylamide polymer used in wastewater treatment.  

Okra works best in ocean water whereas fenugreek in groundwater

Then the researchers tested the plant extracts on real microplastic-polluted water. They collected samples from waterbodies around Texas and brought them to the lab. The plant extract removal efficiency changed depending on the original water source: Okra worked best in ocean water (80%), fenugreek in groundwater (80-90%), and the 1:1 combination of okra & fenugreek in freshwater (77%). The researchers hypothesize that the natural polymers had different efficiencies because each water sample had different types, sizes and shapes of microplastics.

Polyacrylamide is currently used to remove contaminants during wastewater treatment, but the researchers say that okra and fenugreek extracts could serve as biodegradable & nontoxic alternatives.  

Utilizing these plant-based extracts in water treatment will remove microplastics & other pollutants without introducing additional toxic substances to the treated water.

A shift to a circular economy presents a viable solution, and the EU has been increasingly prioritizing efforts in this direction to enhance strategic autonomy and competitiveness.

Bio-based solutions and biomanufacturing are key to the transition, as they enable converting agricultural and industrial waste streams into valuable products like proteins, #biopolymers, and organic fertilizers. Companies that successfully implement these solutions reduce waste and related costs, improve resource efficiency, and create new revenue streams.

Valorization assessment

Tapping into the opportunity requires know-how and infrastructure to develop and scale bio-based solutions. Avecom specializes in this domain by using biomass fermentation.

"We bring to the table 30 years of experience in microbial resource management, a skilled team of technical and engineering experts, and fully equipped labs and pilot or scale-up facilities. With our support, our customers are able to convert an otherwise lost flow into a new product, bringing additional profit to their businesses”, said Stijn Boeren, director of Avecom.

"But the first step in turning waste into a value is the waste-stream valorization assessment. At #Avecom, we conduct technical and economic feasibility studies to help our customers identify the most profitable options for their waste streams”.

While mapping out the technical and economic potential is crucial, the resulting different scenarios must also be evaluated from a regulatory standpoint. This is where Green Alchemy's expertise plays a vital role.

At #GreenAlchemy, we guide companies through complex policies and compliance requirements and make sure that regulatory considerations are addressed from the start. This is how we help our customers make informed investment decisions and avoid costly missteps”, said Claudia Herrmann, co-founder of Green Alchemy ApS. "Our focus is on the bio-based solutions, and we are working with startups and investors in the sector to bring these innovations to the market”.
