Examples of non-recyclable plastics include bioplastics, composite plastic, plastic-coated wrapping paper and polycarbonate. Well known non-recyclable plastics include cling film and blister packaging.
Thus, the correct answer is 'Energy.
Can carbon be recycled?
There has been less focus on the idea of actually reusing or recycling CO2. But science has long known that it's possible to recombine carbon from CO2 with hydrogen from water to make hydrocarbons—in other words, to make familiar fuels such as gasoline.
There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example.
Three Types of Recycling
Here are the three main types of recycling: mechanical, energy and chemical. Every single type is subdivided into minor categories, but understanding them gives us a better idea of how the world processes most of its recyclables.
Glass Facts. Glass is 100% recyclable and can be recycled endlessly without loss in quality or purity. Glass is made from readily available domestic materials, such as sand, soda ash, limestone, and “cullet,” the industry term for furnace-ready recycled glass.
Once a part is cured, it cannot be melted down and recycled into a new part in the same way as plastics can be, and that is why rubber is often a big problem when it comes to the end of its service life.
All types of steel are 100% recyclable and can be recycled an infinite amount of times.
Brown, green and clear glass are the most commonly recycled types but if the glass is contaminated with food or dirt then it can't be processed at the recycling facility. Similarly, heat resistant glass such as ovenware and Pyrex, as well as mirrors and crystal, are not recyclable.
The batteries are valuable and recyclable, but because of technical, economic, and other factors, less than 5% are recycled today.
Explanation: Plastic are difficult to recycle because of the different types of polymer resins in their production. Since each type has a distinct chemical composition, different plastics cannot be recycled together.
The incorrect statement about plastic is (a) It is used to make compost. Plastics are made of non-biodegradable polymers like polyethylene. When buried in soil, the microorganisms take hundreds of years to decompose plastics.
Which of the following is the least preferred method of waste disposal Mcq?
Solution(By Examveda Team)
Bricketting that involves the solidification of preprocessed municipal solid waste into fuel pellets or briquettes is the least preferred method of solid waste disposal.
HDPE is one of the safest forms of plastic due to its stability. LDPE is also considered to be less toxic than other plastics and is relatively safe for use. PP is another safer plastic option for food and drink use, as it can withstand high temperatures and thus is less likely to leach chemicals.
Explanation: Throwing old things do not follow the 5Rs(reduce, reuse, recycle, recover, repair) because i think so.
- Household Hazardous Waste (HHW)
- Construction and Demolition Debris.
- Industrial/Commercial Waste.
- Hazardous Waste Lamps.
- Regulated Medical Waste.
- Used Electronic Equipment.
- Used Oil.
- Waste Tires.
More and more plastic products are labelled as 'compostable', 'biodegradable', 'oxo-degradable' or 'bio-based'. However, plastics made from bio-based materials are not necessarily compostable or biodegradable. Moreover, plastics that do biodegrade can be made from fossil fuel-based materials.
Non-biodegradable materials like glass do not decompose quickly. In fact, glass bottles can stay intact in the environment for hundreds of years. It's thought glass bottles will never biodegrade, but they will break down slowly.
So, the correct answer is 'Fruits'
Ans. Recyclable: Toys, carry boys, cooker handles, ball point pen, plastic chairs, electric wire Rest can't be recycled.
Answer : Polythene bag and PVC pipe are the thermoplastics which can be recycled.
Glass, plastic, metal and paper are all recyclable, as long as they are unsoiled. If necessary, empty and rinse them before placing them in the blue bins.
What is the most recycled product?
Did you know that steel is the most recycled material in the world? In North America, we recycle around 80 million tons of steel each year.
Steel Is the King of the Recycling World
It is 100% recyclable, and can be reused over and over without any quality loss. It is also the most recycled material, per ton, in the world. Here are some more steel-related tidbits; Each year 70 million tons of domestic steel scrap is used in the production of new steel.
Metal: Most metals are easily recyclable. In fact, steel is North America's #1 most recycled material. Additionally, Aluminum cans are one of the easiest items to recycle, as they are 100% recyclable. Turning used aluminum cans into new ones actually uses 95% less energy than making an aluminum can from scratch.
- Garbage.
- Food waste.
- Food-tainted items (such as: used paper plates or boxes, paper towels, or paper napkins)
- Ceramics and kitchenware.
- Windows and mirrors.
- Plastic wrap.
- Packing peanuts and bubble wrap.
- Wax boxes.
Yes! Clothing and textiles are 100% recyclable. You may already donate your gently worn clothes to local nonprofits, take them a consignment store for resale, or participate in online garage sales, but some of your items with rips or stains may not be suitable for donation.
The good thing about metal recycling is that metal can be recycled over and over without altering its properties. The most common recyclable metals include aluminum and steel. The other metals, for example, silver, copper, brass and gold, are so valuable that they are rarely thrown away to be collected for recycling.

Following sorting, there are two main ways to recycle plastic; mechanical recycling, where plastic is washed, ground and melted, or chemical recycling, whereby plastic is broken down into monomers to form new polymers to be reused.
Plastics like clothes hangers, grocery bags, and toys aren't always recyclable in your curbside bin. Other things that aren't recyclable include Styrofoam, bubble wrap, dishes, and electronic cords. Check for facilities in your area that may be able to recycle the items below.
To recycle is to use again or to reuse waste material by converting it into something new. An example of recycle is when you return bottles, which are then processed into new glass products. To extract useful materials from (garbage or waste).
Most plastics can only be recycled once, at which point they are normally converted into clothing or some other commodity which can't be recycled again. This means that once the second item reaches the end of its lifespan, so too does the original plastic – and it ends up in a landfill.
There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example.
Recycling reduces our need for new raw materials.
It also uses up a lot of water and energy. When we recycle, we extract less, which conserves many of our precious (and finite!) natural resources, including trees, water, oil and metals. The more we recycle, the more we protect our resources!
The more we recycle, the less garbage winds up in our landfills and incineration plants. By reusing aluminum, paper, glass, plastics, and other materials, we can save production and energy costs, and reduce the negative impacts that the extraction and processing of virgin materials has on the environment.
