Five examples of biodegradable materials?
paper, cardboard cartons, fruit peelings, leaves, wood basically, most stuff that comes from living things that haven't been combined with inorganic stuff.
How many man-made materials have been developed using science and technology?
Over 100
Why was perl invented?
The Perl programming language was developed by Larry Wall in 1987. It has since been more developed by programmers to revamp the language. In 2000 developers announced a complete overhaul of the language.
Who invented ecdis?
No single individual invented ECDIS. It has been developed by contributions made by companies, institutions and organizations in many countries.
What is a part function?
A part function is where only an item part of an invention or project has been developed by an individual or a group. Not the whole of the full the invention or project.
Why are soluble and biodegradable polymers being developed?
Soluble and biodegradable polymers are being developed because they offer potential solutions to environmental issues. Solubility allows for easier processing and application, while biodegradability ensures that these polymers break down into non-harmful components in the environment. This makes them more sustainable alternatives to traditional polymers that persist for long periods in the ecosystem.
What are alternatives to producing non-biodegradable polymers?
Bioplastics is been recently introduced so as to reduce the use of the traditional non biodegradable plastics.It is biodegradabale polymers
Are most plastics biodegradable?
No. Most plastics are made of compounds and polymers that are not metabolized or degraded by most organisms, although some special organisms have been developed to attack certain plastics. Most plastics are degraded by sunlight.
What are biopolymers?
You should use the biodegradable polymers in day to day life. The routine use of very thin plastic bags has created very real hazard in your life. The This plastic does not decompose and has been creating a serious hazard, specially in developing countries. Stray cows eat the plastic bags, which they can not digest. These plastic waste is washed to sea and sea animals have been dieing due to consumption of plastic material. You can not burn the plastic bags. They create the toxic fumes. So plastic has to be recycled. It is better to use the biodegradable material, which will be ecofriendly in long term.
Why does a cell need to break down polymers into monomers?
Because macromolecules are large molecules and are insoluble. It is easier to store them and use them when they have been hydrolysed to smaller molecules and are made soluble.
Are feathers biodegradable?
Yes. Everything that comes directly from an animal is biodegradable. Watch out for feathers that have been bleached or dyed with chemical dyes though, those are not 100% biodegradable because they leave trace chemicals in the nature.
Is viscose biodegradable?
Viscose is a type of cellulose fiber that has been around since the early 1900's. Yes, viscose is biodegradable and it can be dyed easily.
What are the additives to make polystyrene biodegradable?
The most recent and safest additive that has been used to make polystyrene biodegradable is sugar, first used by chemists in India.
Can polymer paint be sprayed?
Vehicle manufacturers spray the coating on their cars and trucks when they build them. And these paints are almost exclusively polymers. Yes, polymer paints can be sprayed on. The paint and the manner in which it is applied may vary from job to job, but sprayed on finishes are industry standards. And they have been for a long time. The new automotive finishes were developed by chemists who know polymers inside and out. The finishes are tough, long lasting, and resistant to oxidation and chemical attack. They also resist the abuses of sun and wind borne abrasives, as well as remain flexible to resist chipping. These polymers were always developed with the understanding that they would be sprayed on. It was a given.
What is a neat polymer?
A new and usefull polymer is new polymers that are developed to help society- for example shape memory polymers are used to cure cuts.When a shape memory polymer is used to stitch a wound your body tempreture makes it tighter and close around the wound.This is just one example of a new polmer which is usefull. Hope i helped.
How are natural polymers and synthetic polymers similar?
Rubber is a natural polymers with elastic and plastic type behavior. It is found in nature and extracted from trees. PET (soda bottles) Polyethylene Terephthalate is a synthetic polymer and not found in nature.
How are polymers toxic?
Not all polymers are toxic. Plastic for example is a polymer and is made from a non biodegradable material, however, is not toxic unless consumer. Polymers are known to increase risk of cancer, and even radiation poisoning.
