-Exploring the Potential of Foamed Starch for Sustainable Packaging

A groundbreaking endeavor, led by multiple partners in Germany, is set to examine the viability of utilizing foamed starch as a means to create environmentally friendly packaging materials. The initiators of this ambitious project have expressed optimism regarding its initial progress. Their ultimate objective is to provide the packaging and construction industries with an alternative to the commonly used fossil-based foams found in flexible, foamed film applications, which are typically underutilized in recycling efforts, even when properly disposed of in recycling bins.  Chemical recycling platic waste

Currently available foam films, such as foamed polystyrene (PS), polyethylene (LDPE), or polyurethane (PU), often end up being discarded after a single use and subsequently incinerated, resulting in a significant waste of valuable resources. Developing a foamed film using renewable resources like starch would enable these films to be composted at the end of their lifecycle. Sustainable Packaging – automotive

The five project partners involved—Fraunhofer UMSICHT, Loick Biowertstoff GmbH, the Institute for Plastics Processing at RWTH Aachen University (IKV), SHS plus GmbH, and Gefinex GmbH—highlight the potential of foamed starch film packaging in addressing the current disposal predicament within the packaging sector.

The project partners have recently announced the successful creation of initial compounds composed of starch, additives, and biopolymers. Furthermore, the project encompasses the development of economically and efficiently scalable processes for producing these novel films. The partners anticipate that by the end of 2025, they will have generated an industrially viable and marketable product derived from renewable raw materials, offering a sustainable alternative to conventional fossil-based plastics.

Overseen by the Fachagentur Nachwachsende Rohstoffe e. V. (FNR), the joint project, titled “Starch foam films,” is scheduled to span three years. It falls under the funding area of “Development of a potentially marketable, bio-based product” within the “Renewable Resources” funding program. Chemical recycling platic waste

Through this initiative, the project consortium aims to contribute significantly to the advancement of sustainable packaging solutions, paving the way for a greener and more eco-conscious future. Sustainable Packaging – automotive

-The issue of recycling polypropylene (PP) poses several challenges due to the long polymer chains present in the material

When PP is derived from mechanical pre-sorting of various material streams, the resulting melt flow index is often too low for further processing through injection molding or extrusion. To address this problem, the use of peroxide can be beneficial as it shortens the long polymer chains, thereby increasing the melt flow index.

However, working with peroxide comes with its own set of considerations. Peroxide is a flammable, highly reactive, and sometimes explosive chemical, requiring strict adherence to safety regulations during transport and handling. Special protective equipment and dosing technology are necessary for safe handling, and peroxides have limited shelf life even under proper storage conditions. To overcome these challenges, Polyvel Europe, a compounder based in Jork, Germany, has developed the P-Series range of peroxide masterbatches specifically designed to enhance the flow properties of recycled polypropylene. Sustainable Packaging – automotive

Polyvel’s peroxide masterbatches are formulated with additive concentrations of 5%, 10%, and 20% peroxide. They are available in granulate form, which ensures safe handling and facilitates easy dosing. Moreover, these masterbatches have a shelf life of over five years since the peroxide is encapsulated within a polymeric carrier material, preventing volatilization until the time of processing. Chemical recycling platic waste

By incorporating peroxide masterbatches into the recycled polypropylene, the viscosity can be modified in a targeted manner, leading to an increase in the melt flow index. This modification enables the successful processing of recycled polypropylene through injection molding. Furthermore, the peroxide masterbatch can be directly dosed during the injection molding process to further improve the material’s flowability. This enhancement is particularly advantageous when producing thin-walled components with long flow paths, ensuring greater process reliability.

The increased flowability of the polypropylene also allows for lower processing temperatures, resulting in shorter cooling times. This reduction in overall cycle time improves productivity and ultimately lowers production costs. Moreover, the precise and cost-effective adjustment of polypropylene’s melt flow index through the use of masterbatches ensures consistent and reproducible results.

This capability enables the processing of recyclates as a higher-quality starting material, reducing the reliance on primary raw materials in the production of plastic components and products. Sustainable Packaging – automotive

Additionally, the masterbatch granules facilitate the homogeneous distribution of the additive within the polypropylene during compounding. This uniform distribution ensures that the peroxide’s effects are evenly dispersed, leading to reliable and predictable outcomes. Chemical recycling platic waste

With varying peroxide contents available, both small and large melt flow index adjustments can be precisely tailored to meet specific requirements.

While peroxide increases the melt flow index in polypropylene, it has the opposite effect on polyethylene (PE), causing the viscosity to rise. This characteristic offers advantages in recycled film extrusion and blow molding processes where increased viscosity can be beneficial.

In summary, the utilization of peroxide masterbatches in the recycling of polypropylene presents a solution to the challenges posed by long polymer chains. By enhancing the melt flow index, these masterbatches enable the successful processing of recycled polypropylene, resulting in improved productivity, cost savings, and the conservation of primary raw materials. The development of granulated masterbatches ensures safe handling, precise dosing, and uniform distribution, guaranteeing reliable and reproducible outcomes. Chemical recycling platic waste

Furthermore, the versatility of peroxides extends beyond polypropylene, as they can also be advantageous in polyethylene-based processes such as film extrusion and blow molding.

-Traditional Production crude oil Versus shale oil 

The cost of traditional production crude oil and shale oil can vary based on several factors. Here are some key points to consider when comparing their costs:

  1. Extraction Process: Traditional production crude oil is typically extracted from conventional oil reservoirs through drilling wells. Shale oil, on the other hand, is extracted through hydraulic fracturing (fracking) of shale rock formations. Fracking requires advanced technology and additional infrastructure, which can contribute to higher costs compared to conventional drilling.
  2. Reservoir Characteristics: Traditional oil reservoirs are often easier to access and have higher permeability, allowing oil to flow more freely. Shale oil reservoirs, however, have lower permeability and require fracking to extract oil from the tight rock formations. The complexity of accessing and extracting oil from shale formations can add to the cost. Sustainable Packaging – automotive
  3. Production Scale: Traditional oil fields are often large and well-established, allowing for economies of scale in production. Shale oil operations, on the other hand, tend to be smaller and require more frequent drilling of wells to maintain production levels. This can increase costs as additional wells need to be drilled and maintained. Chemical recycling platic waste
  4. Environmental Considerations: Shale oil extraction, particularly hydraulic fracturing, requires significant amounts of water, chemicals, and energy. Implementing proper environmental safeguards and managing waste can add to the overall cost of shale oil production. Traditional oil production also has its own environmental challenges, such as the potential for spills or leaks during drilling and transportation.
  5. Market Conditions: The cost of both traditional and shale oil production is influenced by market conditions, including oil prices, supply and demand dynamics, geopolitical factors, and regulatory policies. Fluctuations in oil prices can impact the profitability and viability of both types of production.

It is important to note that the cost of crude oil production can vary widely depending on specific circumstances, such as the location of the operation, technological advancements, efficiency of operations, and access to infrastructure.  Chemical recycling platic waste

Therefore, providing precise cost comparisons between traditional and shale oil production is challenging without considering specific case studies or data from a particular time period. Sustainable Packaging – automotive

-Shinshu University develops degradation‐free polymer closed loop recycling method: Decomposes into original fine particles when soaked in a solvent

Among the various polymer materials used in daily life, only plastic bottles have achieved closed‐loop recycling and are reused without degradation. The production of polymers continues to increase, and predictions indicate that by 2050, the amount of waste derived from polymers will increase by over threefold compared with the current levels. A research group led by Associate Professor Daisuke Suzuki of the School of Science and Technology, Faculty of Textile Science and Technology at Shinshu University, has developed a material recycling method for polymer particles. By simply soaking the used polymer materials in a solvent, they can be broken down into their original fine particles and reused, resulting in low energy consumption and no degradation. Chemical recycling platic waste

Suzuki said, “We have demonstrated the concept with polymethyl methacrylate, but similar recycling is possible with any polymer composed of fine particles.

Statistics show that one‐fifth of the polymers produced in Japan are composed of microparticles. We are currently conducting joint research with the paint and tire industries, and this research was conducted in cooperation with SEKISUI CHEMICAL CO., LTD. Sustainable Packaging – automotive

We hope to use this method as a design guideline when creating new materials for the next generation.” The result has been published in the journal Green Chemistry.

Polymer microparticles ranging in size from tens to hundreds of nanometers are used in cosmetics, paints, paper processing and other applications. By simply drying a dispersion containing these tiny microparticles, the microparticles can fuse together to form a particulate film. For this reason, they are used in adhesives and paints; however, this has poor strength. Chemical recycling platic waste

Therefore, various chemical reactions can be induced at the fine particle interface using plasticizers, etc., to firmly bind the microparticles and strengthen them. However, once they are formed, the chemical bonds are difficult to break once again, often requiring special chemical reagents and harsh conditions such as high pressure and temperature. In addition, once the interfaces are forcibly broken in this way, recovering the material in a reusable state is challenging. Even if the material could be recovered, its quality would be degraded; therefore, the reuse of fine‐particle films while maintaining their high quality is considered difficult. Sustainable Packaging – automotive

The newly developed method enables recycling by maintaining decomposition at the particulate level instead of the monomer level, as in the conventional method. Specifically, by simply placing the polymer film, or other material to be recycled, in a solvent containing a mixture of ethanol and water in a certain ratio, it can be degraded to the particulate level within 24 hours. The fine particles can be recycled by removing them from the mixture. The yield exceeds 99%, and the film produced after recycling performs at par with that before recycling.
