Shareholders of Phillips 66 Voted for More Openness

A resolution asking the organization to publish a report explaining, among other things, how it could transform its plastic production business from virgin to recycled plastic polymers.

Phillips 66, a Houston-based oil corporation, has approved a resolution calling for greater openness in the company’s plastics production. During a recent meeting, 50.4 percent of the shareholders voted for increased openness, according to As You Sow, a Berkley, California-based charity.

The resolution demands that Phillips 66 issue a plastic report outlining how it plans to transition its plastic manufacturing business from virgin to recycled polymers. It also asks the corporation to evaluate the resilience of its petrochemical assets under five and ten-year virgin-to-recycled transition scenarios, as well as the financial risks involved.

Chevron Phillips Chemical Company is jointly owned by Phillips 66 and Chevron Phillips (CPChem). CPChem is the 15th largest global producer of virgin plastic resins for single-use purposes, according to data released in the Plastic Waste Makers Index.

CPChem sets a target to eliminate plastic waste in its 2020 sustainability report. The corporation was also one of the first large petrochemical companies in the United States to establish a goal of producing recycled plastic polymers. As You Sow, on the other hand, claims that its projected expansions of virgin plastic manufacture are three times more than its recovered plastics goal. By 2030, CPChem’s recycled plastics goal is expected to displace less than 8% of its virgin plastic production volume.

“Petrochemical businesses that are serious about ending or combating plastic pollution cannot justify the continued and rapid increase of virgin plastic manufacture,” says Joshua Romo, As You Sow’s energy and plastics associate. “We hope that this majority vote will prompt the company to review its exposure to the single-use plastic supply chain and provide investors with information on how it plans to mitigate transition risk as the world transitions away from virgin and single-use plastics,” said the group.

Plastic pollution, according to experts, may be approaching an irreversible tipping point. The environmental, climate, and human health costs of the plastic lifecycle are at least 10 times more than the market price of plastics. Single-use plastics are at the heart of the plastic pollution problem, accounting for the majority of ocean-bound plastic waste.

The Pew Charitable Trusts and Systemiq collaborated with worldwide experts to develop As You Sow’s resolution, which is based on peer-reviewed research. It was discovered that existing technology can cut ocean plastic pollution by 80 percent by 2040. This transition is predicated on a global shift to recycled plastics, which has tripled demand for recycled content while reducing virgin demand by one-third, largely for virgin single-use plastic.

“While the plastics industry frequently discusses the need to transition to a circular economy for plastics, American petrochemical companies have not adequately addressed the necessity for or potential impacts of a rapid transition away from virgin plastics,” says Conrad MacKerron, senior vice president at As You Sow. “In fact, as CPChem has proved, several big plastic polymer makers are continually expanding virgin plastic manufacturing.”

Exxon Mobil Corp., the world’s largest producer of single-use plastic polymers, is currently considering a similar plan. Exxon’s annual meeting will vote on it on May 25.

New Camera Technology Can Distinguish 12 Types of Plastic

Scientists from Aarhus University have developed a camera technology that can provide significant benefits in the field of plastic recycling. With this camera, which can distinguish between 12 different types of plastic, it can facilitate the classification and separation of waste plastics.

The study, published in the scientific journal Vibrational Spectroscopy, used unsupervised machine learning on shortwave infrared hyperspectral data to create a model for classifying plastics.

The model can successfully distinguish 12 different plastics commonly found in homes, such as PE, PP, PET, PS, PVC, PVDF, POM, PEEK, ABS, PMMA, PC, and PA12. The technology was also able to identify three more unknown samples, further proving its usefulness, the researchers said.

Generally, the plastic recycling process involves reducing the material and then mechanically separating it with density tests or using near-infrared technology. However, the plastic obtained in this way is between 75-and 95% pure. However, a plastic purity of at least 96% is expected in the industry.

The new technology, led by Associate Professor Mogens Hinge, can identify a wider range of plastic types than NIR technology and also classifies chemical purity in the composition, a promising development for the plastic recycling industry.

Hinge summed up the tech’s process in an interview with Resource: Basically, it’s a camera viewing a conveyor belt. The plastics are then transported from the side of the camera. When the camera takes the images, we use unsupervised machine learning to analyze the images and detect and distinguish individual types of plastic.

“The camera is special because it records images within the infrared range and with multiple channels. For reference, a mobile phone has three channels that make up an image – red, blue, and green. Our IR camera has 90 channels.

“I just want to point out that we use industrial components consciously – this includes all the components and systems in our installation. This means that we do not use highly sensitive, dedicated, specialized, and sensitive research equipment for our work. This restriction is made to ensure the industrial suitability of our work.”

He then explains that the system is “directly transferable to industries.” “Apart from the camera, all you need is a stand to place it on a conveyor belt on the production line. Due to its ability to detect a range of plastic types, the technology allows for the separation of unwanted impurities or unwanted materials from the plastic waste stream.

“This will offer higher purity recycled plastic fractions that can be applied to more demanding products. Hence, ensuring that plastic waste is further recycled (and in some cases fully recycled). We are focusing specifically on the treatment of home-collected plastics and ghost nets from the fishing industry.”

In the next steps of the technology, Mogens said: “We will install the cameras at two plastic recycling companies, Plastix and Dansk Affaldsminimering, which we then need to adjust and adapt the source code and machine learning training algorithms accordingly. ensuring maximum performance in the new environment.”

The research was developed as part of the Re-Plast project, which was funded by the Danish Innovation Fund with DKK 22.7 million.

Plastic Recycling Technologies and Sustainability

Efficient recycling of plastic waste facilitates our transition to a circular economy while helping to reduce greenhouse gas emissions by keeping waste in a circular economy. 

Collection and separation processes are the first steps in the recycling of waste. Improvements in these processes are crucial for higher recycling rates. Plastic waste recycling rates are approximately 10 times higher in separate collections compared to mixed collection schemes. Producing materials that can be recycled and reused reduces the need for resources and provides significant benefits for sustainability. The energy needed for the refining and production processes and saving from the produced emissions are among the important benefits of recycling. 

How Are Plastics Recycled? 

Collection: Collection of end-of-life plastic products from various wastes Initial Separation: Although there is some separation at the collection stage, more separation may be required based on color and thickness. Shredding: Plastics need to be broken down into smaller pieces before they can be reused. 
Washing: Washing removes dust and dirt to ensure the plastics are clean before moving on to the next step. This may include removing traces of food, drink, or labels.  Second Classification and Control: Plastics are re-sorted and controlled before being extruded.  Extrusion: Plastic flakes are finally formed into homogeneous pellets ready for use in the manufacture of new products 

Chemical Recycling is an evolving recycling approach and provides further benefits for scalability. It covers a range of technologies (pyrolysis, gasification, hydrocracking, depolymerization) that alter the chemical properties of plastic waste. The long hydrocarbon chains that make up plastics are broken down into shorter hydrocarbon fractions or monomers using chemical, thermal, or catalytic (chemical/thermal) processes. These shorter molecules are ready to be used as raw materials for new chemical reactions to produce new recycled plastics and other chemicals. It is a complementary technology with significant potential. 

Dissolution recycling is a purification process that allows the polymer in mixed plastic waste to be selectively dissolved in a solvent, separated from the waste without changing its chemical structure, and recovered in its pure form. Several industrial examples of this type of technology already exist and are applied to different polymers such as polyvinyl chloride (PVC), polystyrene (PS), nylon (PA), or polypropylene (PP) to separate them from mixed, multi-material waste. 

Organic recycling is defined as the controlled microbiological treatment of biodegradable plastic waste under aerobic conditions (composting) or anaerobic conditions (bio gasification). It applies to specific polymers that can be converted to stabilized organic residues, carbon dioxide, methane, and water under the influence of microorganisms. 

Plastic Recycling and Sustainability 

To move to a sustainable and circular plastics economy, we need to invest in a zero-waste future, collaborate and develop new technologies. It is an issue that the actors in the plastics recycling sector should focus on if they are to follow new technologies and seize opportunities for the recycling of plastic, which is a material that has many roles in achieving the Green Deal goals and ensuring a sustainable future. 

The laser melt filter system, one of these new technologies, provides significant benefits to plastic recyclers in terms of money and labor savings. 

With all this, efficiency in plastic recycling can be achieved by improving the automation of the melt filter system used, the level of pollution removal, ease of use, and maintenance cost. 

For example; No need for the operator to change the filter, reducing the need to change sieves, maximum impurity output and minimal melt loss save both energy and money, and increase the amount of successfully recycled product, thus protecting the environment and using resources better. 

GP Technology company’s GP DUAL F500 laser filtering system, based on the important experience gained in the sector, has been developed to provide great benefits to manufacturers, the economy, and the environment in plastic recycling by having the above-mentioned features in the best way.

As a result, the use of new technologies in plastic recycling is of great importance in terms of the transition to a circular economy and sustainability. It gives hope for the future to see manufacturers make fast and accurate decisions to follow and effectively use these technologies on behalf of both themselves and the society and the environment. 

The Importance of Plastic Recycling for More Sustainable Businesses   

An average of 75% of plastic produced worldwide becomes waste plastic, but less than 10% is recycled. Up to one-third of all plastic waste pollutes freshwater, seas, and soils in nature, where it can take hundreds of years to decompose. It causes great damage and loss of biodiversity in the polluted ecological system and harms human health.   

 For an environmentally friendly production process, some companies may avoid the use of plastic, while for others, this does not seem possible for now. For such businesses, it is of great importance to switch to reusable materials. A pleasing fact in this regard is that the transition to the use of recycled plastic is accelerating as businesses realize the environmental and economic benefits of plastic recycling. For example, Adidas has promised to use only recycled plastic in all of its clothing and shoes by 2024.  

So what exactly is recycling?  

 In summary, recycling is the reuse of used and waste materials. In other words, the material that becomes waste is either converted into raw material to produce a new product again or directly converted into a new product. Reducing the need for raw materials for the production of new products and reducing the pollution caused by the disposal or incineration of wastes are among the biggest benefits of recycling to the environment.  

 Therefore, recycling has become an important part of many companies’ sustainability strategies. Of course, reliable third-party assurance has become crucial to verify the accuracy of the claims of organizations claiming to use recycled materials in their products.   

 GRS (Global Recycled Standard) and RCS (Recycled Claim Standard) are highly trusted and established standards that set requirements for third-party certification of manufacturing processes claiming to use recycling. The purpose of these standards is to increase the use of recycled materials in products.  

 These standards encourage businesses to be conscious of reducing plastic waste in their production processes and to focus on resource efficiency. According to the GRS or RCS, certification allows consumers to believe that the business they are purchasing is taking positive steps to protect the environment and reduce the impact of plastics.  

Better Recycling for Sustainability, and Right Melt Filter System for Better Recycling   

 As the importance of calculating the environmental impact of production processes and protecting the environment is understood, plastic recycling is increasing. For this recycling process to be more sustainable, the process must be financially and energetically efficient for the producers.   

 Efficiency in plastic recycling can be achieved by improving the automation in the melt filter system used, the level of pollution removal, ease of use, and maintenance cost.   

 For example; The operator does not need to change the filter, reduces the need for sieve change, maximum contamination output, and minimum melt loss both save energy and money and increase the amount of successfully recycled product, thus protecting the environment and making better use of resources.   

 The laser filtering system of GP Technology company, named GP DUAL F500, has been developed based on the important experiences gained in the sector to provide great benefits to manufacturers and the environment in plastic recycling by having the above-mentioned features in the best way.

 As a result, in our rapidly developing and changing world, the recycling sector, especially plastic recycling, has gained great importance in recent years, when we have seriously realized the importance of the environment. Companies that want to increase their sustainability are rapidly reducing their use of plastic or switching to the use of recycled plastic. Using more efficient plastic recycling systems is now almost a necessity, so investing in systems that recycle with less cost and better quality seems like a decision that should be taken before it’s too late for many companies.  

 With the hope of more sustainable production chains and a cleaner and more livable world…
