– Chemical recycling according to Versalis
Let’s take stock of the Hoop project with Fabio Assandri, R&D manager. Objectives: flexibility with respect to fed waste, high yields and naphtha-like quality to make the process sustainable.
Hoop is a project launched in 2020 by Versalis in collaboration with the Italian engineering company Research and Development Services (S.R.S.) for the chemical recycling of mixed plastics, now destined for waste-to-energy or landfill.
To find out more about the technology and the progress of the project, on the occasion of Ecomondo we met Fabio Assandri, Head of Research, Development & Technological Innovation at Versalis .

How did the collaboration with S.R.S. ?
It was chosen as a partner because it already had a very effective reactor prototype for the pyrolysis of mixed plastics aimed at fuel production. We started from here to develop a technology that, always starting from heterogeneous plastics, could provide a raw material to be reintroduced into cracking to produce plastics and intermediates.

How is it different from normal pyrolysis processes?
We are optimizing the different phases in order to make the process more sustainable and obtain yields around 80-90% compared to fed carbon, ie between 15 and 20 percent higher than conventional pyrolysis plants; and with a quality of the pyrolysis naphtha, in a single cut, very close to that of the feedstock of fossil origin that we use today to feed our cracking plants. We believe that these two aspects, yield and quality, are the key points to successfully exploit the pyrolysis of heterogeneous plastics. For this reason we have preferred to develop our own technology, investing time and resources, instead of adopting a chemical recycling process already present on the market.

What aspects of pyrolysis are you working on?
It should be noted that pyrolysis in the strict sense is only part of the chemical recycling process. Yield and quality depend on the synergies and optimizations of three phases: selection and preparation of the plastic waste, with the elimination of extraneous fractions up to obtain compacted flakes corresponding to a specific specification. We then move on to pyrolysis, which is a chemical process, from which a mixture of hydrocarbons is obtained with the help of heat; the technology we have identified is of the thermal type, in two steps with separate reactors, which has the advantage of being able to modulate the operating conditions according to the material fed. The third phase is the treatment and modification of the pyrolysis oils to obtain a naphtha-like to be reused in the cracking phase to produce first the monomers and then the polymers.

-Green Synthesis of Silver Nanoparticles Using Beetroot Extract

The latest research published in the journal Science Advances revealed that the microbes present in various hospitals and textile products are a major cause of death.

The research by Mr. Otávio Augusto and his team has shown that manufacturing antimicrobial textiles for hospitals would be advantageous for the termination of such bacteria and fungi.

The green process of synthesis of silver nanoparticles (AgNPs) is highly beneficial for hospital cotton fabrics.

Beta vulgaris extract was efficiently used for manufacturing such green germ-killing smart textiles which could be used in hospitals for sheets and pillows to prevent the spread of dangerous diseases by contact.

Silver Nano Particles

The Silver Nanoparticles utilized for this study were on the scale of 1 to 100 nm. They are synthesized in a reaction medium which is useful for the generation of a stable nucleus.

The step called growing forms larger particles, and the thorough modification of stabilizing components is responsible for particles of various sizes and shapes. Since the chemical as well as physical processes are costly and utilize toxic compounds, the synthesis and utilization of nanoparticles become a great difficulty. Hence, green synthesis is the only viable option.

Methods and Materials Incorporated in Green Nanotechnology

The green nanotechnology synthesis utilized in this study is mediated by plant extracts, cell extracts, algae, and other biomolecules. The plant extracts are highly appreciated for their cheap and efficient processes. Ionic breakdown in the liquid system of a metallic substrate is the process for sustainable nanoparticle development of AgNPs. Silver ions are reduced to silver and a nucleation process is initiated. This is essential for the stabilization of nanoparticles. Nanotechnology PET Recycling Recycling

Beta vulgaris beetroot was efficiently utilized. It was cut into 2-3cm long pieces and heated to boiling point. Solution extracts were filtered and stored at a low temperature around 4 °C. The Ag nanoparticle synthesis was carried out in the exact proportions of 1:50, 1:25, 1:10, 1:5, and 1:2.

-Instantaneous hydrolysis of PET bottles: an efficient pathway to the chemical recycling of condensation polymers

Restoring the environmental balance that was disturbed by the rise of plastic commodities is a must for researchers and the wider community. It is imperative that the increasing amount of plastic waste and that the high amount of petrochemical resources consumed during the constant replacement of single-use plastics is reduced. Poly(ethylene terephthalate) (PET) is one of the most commonly produced single-use polymers in the world, and its mechanical recycling is challenging due to the loss of properties during reprocessing.

Chemical recycling is a feasible alternative to reclaim the monomers, however, its viability relies on establishing a straightforward, fast, and inexpensive procedure to turn the end-of-use polymer into new pure monomers. Nanotechnology PET Recycling Recycling

This work reports on the fastest known procedure for PET chemical recycling to produce terephthalic acid and ethylene glycol in an efficient and straightforward manner, thanks to microwave-assisted heating that permitted 100 % PET conversion into TPA in just 1 minute at 120oC.

The depolymerization kinetics of this new procedure were studied and its improved efficiency over other reported hydrolyses procedures was attributed to a thicker shrinking layer.

This new procedure may form a major breakthrough in chemical depolymerization. Evidence pointing to the higher reactivity of free OH species, enabled us also to obtain dimethyl terephthalate (DMT) through the use of an anhydrous depolymerization system that is able to convert PET into DMT in 4 min at 80 °C, but requiring careful humidity control.

-It’s time for a UK zero-emission vehicle (ZEV) mandate

Tanya Sinclair argues that a ZEV mandate will prove pivotal in increasing EV sales, particularly for the UK in light of its coming ICE ban

Last year the UK government announced plans to end the sale of all new diesel and gasoline cars and vans by 2030, five years earlier than planned. In Europe, similar climate targets will result in effective bans on these vehicles by 2035.

In the US, California, the world’s fifth-largest economy, will also discontinue gasoline-powered passenger vehicle sales by 2035. Canada is doing the same.

Whilst Britain’s more ambitious timetable is laudable, the key to meeting all of these targets is not the date-setting itself, but ensuring there is a clear roadmap to get there. This is why more urgent action is needed today to increase the adoption of zero-emission vehicles (ZEVs).

What does that action look like? In addition to ending the sales of fossil fuel vehicles, the government must impose a ZEV mandate.

A ZEV mandate, based on a successful model adopted in California, would set a requirement on vehicle manufacturers to sell a certain percentage of zero-emission vehicles in the UK each year, rising overtime to reach the government’s 100% target in 2030. Nanotechnology PET Recycling Recycling

For each ZEV sold, the manufacturer would receive credits based on the car’s electric driving range. Once the automaker reaches the annual number of credits it needs for compliance (based on overall ZEV sales), it is free to hold onto any additional credits or to trade or sell them to competitors.

-Effective Packaging in the Circular Economy: A Global View

Sustainability is an increasing priority for consumers when making packaging-related decisions, and often is central to a product’s visual appeal.

What I have experienced in recent months is that many businesses have yet to prioritize sustainability and circularity when considering the design, use, and disposal of packaging, with the majority of packaging still single-use and non-recyclable. This needs to change, and consumers can force that change to happen more quickly.

Sustainable packaging has been a priority for some brand owners for more than a decade. As we move through the last quarter of 2021, we are seeing appropriate activities that address consumers’ eagerness for brand owners that show the respect for the environment that judicious customers want to see. Consumers’ increased awareness continues to drive the sustainable packaging mission of brand owners. By one estimate, 74% of consumers say they are willing to pay more for products that are packed in sustainable materials.  Nanotechnology PET Recycling Recycling

Circular packaging solutions emerge

An encouraging development is that several organizations are attempting to improve this bleak course by investing time and money in the development of more circular packaging solutions. These leaders are creating solutions where packaging waste is either infinitely reprocessed or can re-enter the system as raw materials for other products. This is a good example of the circular economy in action. This is great news, and not just for environmental reasons.

-Automotive polymers

Metal used to be the dominant material in the automotive industry – for bodywork, engines and interior parts. Those days are long gone. Today, about a third of the roughly 30,000 parts in cars are made of plastics. Four polymers account for over 70 percent of the plastics used in the industry: polypropylene, polyurethane, polyamide and PVC. Automotive polymers are the raw materials for the manufacture of automotive plastics. While all plastics are polymers, not all polymers are plastics. Plastics do not occur naturally; they are produced by chemical synthesis. By contrast, polymers may be either natural or synthetic. In this text, the terms automotive polymers and automotive plastics are used interchangeably, as they are in everyday use.

There are good reasons for the increasing use of automotive polymers. They offer enormous freedom in the design of interior and exterior parts, and they are durable, have good haptic properties, and are abrasion- and vibration-resistant. Moreover, they are easier to process and offer an improved price-performance ratio. Polymers have also received a big boost from the trend to lighter weight vehicles.

Since plastics are lighter than conventional materials, they help to improve fuel efficiency and could reduce greenhouse gas emissions. Together with good recyclability, plastics therefore play a part in meeting present and future sustainability targets. Both established and new polymers meet these challenges.
