Yes, I agree to recycling of waste with strong view to minimize use of plastic waste where we can

and one of the remedies to control its impact on environment is reuse in prevailing materials like we have used in concrete

Yes recycling of plastic waste is a must in the present context...we cannot reduce its use due to its flexibility but we can surely re use it to minimize its impact on the environment.

Thank you very much!

Thank you very much!

Plastic use is unavoidable, so the plastic waste may increase further. Therefore we must find a suitable method to recycle the waste hence more researches are expecting.

Thank you Dr. Muzathik.

Following an answers.

Yes

Plastic waste based engine may be created to eliminate burden of plastic waste and environmental concern has to be seen in implementing this type of engine

Thank you!

I agree they should recycle, in fact many countries are using plastic waste to build and repair roads.Examples are India and the Netherlands, if I am not mistaken.

I wonder can plastic waste be used as a concrete additive as a partial aggregate replacement?

yes of course it is vital problem for human.

There are plastics and there are plastics. Recycling of some of them is not only expensive but also so toxic to human health that it is better to build special underground-water-impervious storage facilities. I understand perfectly well that the latter is extremely expensive, but at the moment I see no other way out.

Nowadays recycling of some common-structure copolymers is a modern subject. I myself work at the laboratory where biodegradation is studied. But I am not sure that the soil which is used for this purpose can be ever reused in agriculture.

Yes, it's a very pessimistic comment - but everything above said is true. A bitter truth - and we will have to deal with it.

Thank you very much for your comments.

It is useful for industrial.

Recycling plastic waste any time

Burning of plastic in the open air leads to environmental pollution due to the release the chemical poisonous.

Yes, Plastic recycling is a hot topic for research nowadays. Plastic is a cheap, available product for packaging every kind of goods but Soil, water, animals, everything is affected by plastic waste. Some countries are recycling plastic waste like using plastic to produce energy (like Denmark & UK and some other European and African countries), some countries like India, Nederland are recycling plastic to produce concrete, building materials, construction materials and other materials for use.

Thank you.

It is estimated that 1.1 to 8.8 million metric tons (MT) of plastic waste enters the ocean from costal communities each year. Plastic wastes are harmful for living organisms, particularly marine animals, can harm either by mechanical effects, such as entanglement in plastic objects or problems related to ingestion of plastic waste, or through exposure to chemicals within plastics that interfere with their physiology. So plastic recycling is a must. But we have to give more focus on researching biodegradble plastics. If plastics become biodegradabl, it will become much less harmful

Thank you Dr. Ahmed.

There is no doubt that current plastic materials are a very huge problem for people all around the world. The current problem can be tackled by effectively implementing the 4 R's (refusing, reducing, recycling, reusing) principle.

In future, the better solution will be to working on the chemical composition of the plastic so that they can be made biodegradable by introducing a chemical component that can alter with time and use making the plastic naturally degradable over time.

Plastic waste should be isolated, compacted and sanitary landfills. Because plastic waste recycle produces uneconomical products and causes new pollution

Thank you very much!

Plastic waste is deteriorating cultivable land.

Right. The land is used not for production plants

Thank you.

Plastic wastes are slow to degrade and pile up in solid waste disposal sites. They also find their way into oceans causing problems for fish and birds. An ingenious method for recycling plastic wastes includes crushing them up and mixing them with asphalt for road paving. It is being used in India and other countries should follow suit.

Thank you Dr. Vasan.

Plastic has toxic pollutants that damage the environment and cause land, water, and air pollution. It can take hundreds or even thousands of years for plastic to break down, so the damage to the environment is long-lasting.

Recycling is the best option.

Thank you.

Hi

Once a commodity entered into market and people used to use it, it takes much longer to reduce or stop it. The only solution is recycling and related technologies.

Thank you.

Thank you Dr. Singh.

Thank you.

Recycling is one area.

Need to focus on the other kinds of managements including reduction as well. For example, there are certain kinds of plastics where recycling is not easy. In that case reduction is the answer. Some cases, second use is also an option (for example, energy production).

recycling it is the best solution due to the importance of plastic in our daily life but reasercher have discovered a new bacteria that could eat plastic enhacing in the same time his degradation.

I believe that it is a must to pas to less packaging and the use of natural stuffs for packaging.

Thank you.

It is so benefit for recycling but environmental pollution must be taken into account.

Thank you.

Plastic is into clothing and cosmetics. Clothing (fleece, nylon, acrylic, polyester) releases minute plastic fibres when washed. Each item of clothing does not release thousands of fibres during washing, but releases millions of fibres. These are so small that they pass through sewage treatment plants. Ten percent of some cosmetic and toiletry products are made up of microplastics. The institute counted the microplastics in one single toiletry product and found 360,000 pieces of plastic. These go down the sink or shower drain and flow straight out to sea. They are eaten by marine animals and plankton and then enter our food chain.

Thank you Dr. Kumar.

In developing countries where there is NO recycling of plastic waste they have serious environmental issues. I strongly recommend recycling plastic waste.

Thank you Dr. Famiyeh.

We look at the decomposition of any matter in the environment

The non-biodegradable material is recycled

Thank you Dr. Ali.

Thank you.

I think that the first priority must be given to minimizing the use of plastic so that no more plastic waste is created also look for alternatives that can replace plastic.

Thank you very much!

This is one of the most priority area where recycling of plastic should be there. In India, there are some states where polypack (eg. Polythene bags for carrying vegetables and other things) are banned.

Recycling

Thank you Dr. Abdal Kareem M.A Dawagreh.

I think the focus must be multi-fold for example many products are packaged in non-recyclable plastic all food packaging should be recyclable.

Then non-necessary packaging should be removed not only with plastic but all non-essential packaging.

Care in replacement or alternative materials so we don't remove a plastic source and replace with something toxic or hazardous in a different way.

Recycling existing waste should be a high consideration but not used as an excuse to produce more waste.

Thank you very much!

Thank you Dr. Ilieva.

Thank you Dr. Al-Homaidan.

A key issue which needs to be given much attention or audience before it gets too late. As majority (90%) of plastic waste are not recycled except some specific kinds of plastic like remsins and PTPs. This means a larger chunk ends up somewhere which indirectly impacts upon us.

We need more innovative ways to reduce, re use/recycle our waste

Any kind of waste should be a constant reason for scientific research. Due to the excessive consumption of plastics, research studies on this topic and its residues should always be stimulated and encouraged.

Thank you Dr. Pereira.

It is one of the most important threats that threaten our future. There must be a universal solution.

Thank you Dr. Unluoglu.

My opinion about plastic wast must to be do many research for replacement some plastic industries to others that do not harm the environment

Thank you Dr. Alhashemi.

Yes, non-biodegradable plastic waste is one of the most important problems of environmental pollution. Plastic also poisons the seas and oceans. Tons of plastic packaging are inundation at the bottom of the seas and oceans. Plastic bags break into small fragments, they are eaten by fish that are poisoned with plastic. Thousands of plastic bottles float on the surface of the seas and oceans. The plastic is not biodegradable or breaks down after thousands of years. Plastic bottles in forests can cause a forest fire. In some countries, a recycling system for plastic PET bottles is already developed and drinks in these bottles are sold with bail, ie a reduction in the price of the product for the recycling of plastic bottles. In the European Union, by 2021 plastic will be withdrawn from the packaging of sold products and replaced with biodegradable materials, e.g. produced from cereals. For many years, technologies have already been known for the production of plates, cutlery from rice, cereal bran, but they have not been introduced on a massive scale. Legislative reforms are needed that will force producers to replace environmentally toxic plastics with biodegradable materials. this process has already begun, but too little has been done on this issue. Such pro-ecological reforms should be implemented in all countries of the world and not only in some, because this is a global problem.

Best wishes

Thank you very much @Dr. Prokopowicz.

One of the challenges faced in recycling of plastic material is the diversity of polymers (e.g. LD/HDPE, PET, PS, PVC, PP, polycarbonate, polylactide, acrylic, acrylonitrile butadiene, styrene, fiberglass, and nylon) as well as the type of additives (plasticisers, UV stabilisers, thermal pro-oxidants to name but a few) used. Either we manage to develop a new generation of plastics which contain additives that are easy to separate from the polymer matrix during recycling, or we only allow plastics to enter the market that can be reused many times before complete or partial energy recovery. In the case of partial energy recovery conversion to char can still help to lock up some carbon while the char can be tested for use as soil ameliorant or other applications (Article 55 Uses of Biochar

The one-time use of biodegradable bioplastic material is not solving the problem, to the contrary, they have a greater water and land-use footprint for example. Again multiple reuse with either subsequent energy recovery and/or conversion to char should be the goal.

Thank you Robert Thomas Bachmann .

Recycling must be a priority for plastic waste.

recycling with a very efficient collection system of used plastic ... in this regards, community awareness should be given the highest priority... plastic can save or destroy our environment... it will save or destroy will depend on how we are handling it

Dear Laura Bulgariu ,

having read 82 replies plus your own view, what conclusions would you draw regarding plastic waste recycling as a priority research area?

Thank you for the comments, Sadanand Pandey

Thank you Fares F. Fares

Thank you Shahab Uddin

Thank you Robert Thomas Bachmann

Thank you Jasim Hassen

So, what about plastic waste: how to get rid of it?

Where are the answers/the approaches to the problem?

In the above discussion I saw only the wish - to find the solution to this problem.

Dear all, basing on Lavoisier principle the matter may transform to other forms. So for me there is no wastes either plastics or other materials, it is our limitations that are obstacles to find other issues to accomodate used objects. My Regards

As being versatile material, It is difficult to stop the use of plastics completely. Plastic waste is a serious concern nowadays. Recycling of plastics into reusable raw materials as well as development of sustainable biodegradable plastics are demanding and need dedicated research.

Thank you Abdelkader BOUAZIZ

I agree with all that has been said and recommend reading attached.

Thank you very much Ronei de Almeida

The environmental threat posed by the egregious amounts of plastic waste that have accumulated over the years, and that will likely continue to increase unabated.
