Plastic bottles banned from landfills

One of America's biggest PET bottle recycling plants is set to open in Fayetteville next year.

It better not be counting on the surrounding area for raw material.

Seven of the Cape Fear region's 10 counties, including Cumberland County, finished in the bottom third of North Carolina counties for recycling PET bottles last year.

The region has nowhere to go but up. A state law taking effect Thursday could help. Recyclable plastic bottles with screw tops or snap caps will be banned from landfills.

In a region where tons of the bottles apparently end up in landfills every year, will people who don't find it easy being green have anything to worry about?

Enforcement of the law is critical, said Ron Salati, general manager of Clear Path Recycling LLC, which is building the Fayetteville plant.

"It's going to be a difficult task," said Salati.

Others outside government are more skeptical.

On the Web site of the political-chat television show "NC Spin," a blogger asked: "What good does it do to pass a law requiring citizens to recycle plastic bottles if there is no penalty when they don't?"

The legal burden will fall largely on landfill operators rather than consumers.

"There's not going to be a recycling police," said Jerry Dietzen, head of Fayetteville's Environmental Services Department.

The N.C. Department of Environment and Natural Resources will watch for large quantities of plastic bottles being dumped in landfills, said state recycling coordinator Scott Mouw.

If a waste hauler is spotted with a lot of bottles to dump, Dietzen said, state inspectors will try to trace the load to find out who threw the containers in the trash. The inspectors will acquaint those responsible with the new law, Dietzen said.

But inspectors may sanction landfill operators for disposal violations, Mouw said, just like the state does now for windblown debris or polluted groundwater.

Salati said Clear Path will accept any help it can get. "Anything that's kept out of a landfill is additional product that's available for recycling for us," he said.

County rankings

The latest state figures suggest Cumberland County could be doing more for the new hometown business.

The county recycled barely half a pound of plastic bottles per resident in 2008. That was 87th out of 100 counties in the state.

Orange County led the state by reclaiming nearly 30 pounds per resident.

But those figures are more than a year old, covering a 12-month period that ended June 30, 2008. Fayetteville started a successful curbside recycling program the following week.

Dietzen promised that Cumberland County's 2009 numbers will improve. "Ours are going to go way up with the next report," he said.

That report, due in December, will cover a period that coincides with the first year that the city picked up recyclable material at single-family residences.

Besides curbside pickup, Dietzen said, the city has begun collecting plastic bottles from public buildings and will start doing the same at athletic fields this fall.

The best bottle recyclers in the Cape Fear region were in Scotland County. More than 5 pounds of bottles were recovered last year for every county resident, good for 26th place in the state.

"It has to start with the county commissioners," said J.R. Horne, Scotland County's recycling coordinator.

Horne estimated that 80 percent of Scotland County residents recycle household waste weekly.

At the other end of the regional scale is Harnett County, where a task force reported last year that just 20 percent of residents visited recycling drop-off locations.

That might explain why Harnett County had just about the worst rate of bottle recycling in the state last year. Four smaller rural counties that don't recycle plastic bottles or failed to report to the state finished below Harnett County.

Jerry Blanchard, director of the Harnett County General Services Department, blamed the state reporting process.

Harnett County accepts commingled material at its seven drop-off locations. So, Blanchard said, the county has trouble reporting the volume of bottles or aluminum cans that are recycled because the waste arrives mixed together.

Nevertheless, Harnett County also fared poorly when all recyclable material is considered. Last year, only Robeson County recycled less total material than Harnett County in the Cape Fear region.

Jon Parsons, executive director of the regional environmental group Sustainable Sandhills, said Harnett County has increased the number of materials accepted for recycling as a result of the recycling task force's work.

"I expect that Harnett's ranking will also improve in the next year's report," Parsons said in an e-mail, "although I wouldn't expect as much improvement as Cumblerland's."

Nationwide trends

Harnett County isn't out of step with the rest of the country. Americans recycle less than 25 percent of their plastic bottles.

Salati said recycling rates jump above 60 percent in states with bottle-deposit laws, such as California and New York.

Weak as North Carolina's new law is, Salati said his company is glad for it.

Unfortunately for Clear Path, increased recycling in the vicinity of the new plant won't boost efficiency much.

By 2012, when the plant is expected to be fully operational, it will be able to handle 20 percent of all polyethylene terephthalate bottles, or PET, that are recycled in the nation. PET bottles have the number 1 embossed on the bottom.

The Fayetteville plant will be capable of handling 280 million pounds of the bottles in a year. The recycled material will go into polyester-based products made by Clear Path's owners, Charlotte-based DAK Americas LLC and Shaw Industries Group Inc. of Georgia.

Yet even if Clear Path recycled every PET bottle discarded in the state, Salati said, the plant would still operate at less than half of its capacity.

Clear Path will need to bring in plastic bottles from 48 of the 50 states, he said.

Infrared dryer

Operation principle of the Infrared dryer:
The drum having wide,shallow spiral channel and paddle inside,can be revolved slowly.The paddle will mix the material while the drum is rotates.The material move ahead gradually along the axis of the drum under push of spiral channel. At the same time the infrared ray which is sent by infrared ray generator and air flow around remove the moisture out of material. The residence time of material staying in the drum is about 20 mins(Residence time depends on actual situation of the material).During this time,the material is not only crystallized but also the moisture has fallen greatly.when PET is used for blowing bottles or other processing whose requirement of moisture is really high,we need additional drying to make sure the moisture.So we equip simple traditional dehumidifier to be acted as buffer hopper before the material
Prosperty:
A.Compared with traditional dehumidifier
Infrared crystal dehumidifier finish the processing:crystal,dehumidifying,drying
at a time.
Short drying time,lower energy consumption,high efficiency.during the
processing of dehumidifying,no breaking the structure of material molecular,to
keep the property of material;We have get German Patent for Infrared crystal
dryer

B.Good for drying material:PET?PC original material and recycling material;PE?PP particle;It can be also used for drying waste food and so on.

Recycled plastics offer commercial and environmental benefits

Recycled plastics offer commercial and environmental benefits

Manufacturers of products incorporating plastics are finding recycled materials increasingly attractive, both for economic and marketing reasons. Alistair Rae looks at the options available and the latest developments in recycled post-consumer plastic waste.

Modern life would be impossible without the features and versatility plastics bring to products and packaging, but a lot of resources are consumed in their manufacture and they are often disposed of inefficiently. Fortunately designers now have more opportunities to select materials that incorporate recycled materials. It makes economic sense, reduces the need for crude oil and, consequently, reduces greenhouse gas emissions.

There are five high-volume families of plastics. These are the polyethylene family (low-density and high-density PE), polypropylene (PP), polyvinylchloride (PVC), polystyrene (solid PS and expandable EPS) and polyethylene terephthalate (PET bottle recycling ). Between them they account for about 75 per cent of all plastics demand (Fig.1).

For post-consumer recycling, plastic types are usually referred to using the Society of Plastics Industry (SPI) resin identification codes (Table 1). Most plastics can be recycled, but they have to be separated into their different polymer types. Furthermore, while thermoplastics can be remelted, thermosetting plastics need to be reprocessed in other ways.

Polyethylene (resin codes 2 and 4) is widely used in domestic and industrial applications and its typical uses are crates, containers and drainage pipes. It is fully recyclable, though any contaminants and hazardous substances have first to be removed.

Polypropylene (resin code 5) is widely used for engineering products, especially in the automotive sector, and can be recycled up to 50 times without any reduction in strength.

Polyvinylchloride (resin code 3) is used in the construction industry and for packaging. PVC is recyclable unless this is prevented by the presence of other polymers.

Polystyrene (resin code 6) is an excellent packaging and insulation material, but it is difficult to recycle. However, it can be reprocessed into new plastics for use in the building industry.

Polyethylene terephthalate (resin code 1) is commonly used for lightweight plastic bottles and (depending on purity) can be recycled into new PET products or processed into other polyester products and fibres/fabrics.

Recycling options

When recycled, plastics are often used in lower-grade products than their first use (sometimes referred to as downcycling) but high-purity recycled material can be added to virgin polymer when making new products. Known as 'closed loop recycling', this is also the name of a UK company that reprocesses plastic bottles to create food-grade quality material (see panel).

"Separating of waste into different polymer types used to be an issue, along with the quality of material being recycled, but techniques have improved," says Stuart Foster, business development director for Recoup (Recycling of Used Plastics Limited), an independent organisation devoted to developing plastics recycling in the UK, promoting best practices and providing educational and training tools. "The situation in the UK at the moment is that bottle recycling capacity exceeds the amount being recycled, although domestic mixed plastic is the opposite, with sorting and reprocessing at an early stage of development. The commercial sector is very much dependent on the quality of material being recycled. In the end it is entirely down to economics whether recycled material can compete with virgin polymer."

There is more to recycling than just getting more use out of waste material, as the market is driven by consumers who make selections based partly on environmental impact and manufacturers who recognise the need to demonstrate their 'green' credentials as part of their marketing mix.

The EU's Waste Electrical and Electronic Equipment (WEEE) Directive sets recycling and recovery targets for all types of electrical goods, and this is now resulting in large volumes of post-consumer plastic materials becoming available for recycling rather than being sent to landfill (Fig. 2). Plastic re-processors like Axion Polymers take this waste from the electrical and electronics sector for recycling.

"We start with untreated waste, which includes a whole range of plastic materials and contaminants, and using the factory process we have developed we remove the impurities and produce high-grade polymer resin for use in injection moulding," says Keith Freegard, director of Axion Polymers. "Production batches are traceable back to the origin of the raw material as part of the certified manufacturing process."

This material is used by European injection moulders and extruders looking for economies, where the value of using recycled material is, in itself, low. It is also used by brand-leading OEMs wishing to promote themselves as users of closed-loop recycled raw materials.

From fridges to washing machines

A project run by Axion and the Waste & Resources Action Programme (WRAP) has helped Indesit to introduce recycled content into its Hotpoint Aquarius and Ultima washing machines. The back access ports of the washing machines are now covered with a plate made of recycled ABS that was produced from shredded plastic waste recovered from fridges.

"This groundbreaking project shows that closed-loop recycling in electrical equipment from UK WEEE is commercially viable on a large scale," says Peter Maddox, Head of manufacturing at WRAP. "We encourage other manufacturers to follow this example."

Mike Birch, environment manager at Indesit Company, states: "We now plan to roll out the innovation to a range of our washing machines and washer dryers that are produced each year. The cumulative cost and raw material savings will be significant and the improved price helps to deliver a project with environmental benefits, which we felt was the right thing to do."

Freegard adds: "The important thing is for us to make designers aware of these recycled material sources so they know that they are available to be used."

Mobile phones have recently been launched by manufacturers such as Sony Ericsson (C901), Nokia (3310 Evolve) and Motorola (Moto W233 Renew) incorporating recycled plastics; one of their marketing messages is that these products are more environmentally friendly than earlier models (Fig.3). This is a worldwide market in which CO2 reduction and recycling are seen as important by many customers.

Low-grade mixed waste is the most difficult to recycle, and this has resulted in new technologies being developed. Powder impression moulding (PIM) is a patented process that allows products to be made from mixed low-grade waste plastics that would otherwise be sent to landfill. For example, 2k Manufacturing produces Eco-Sheet for use as an alternative to plywood in the building industry. "Eco-Sheet has replaced plywood on the site hoarding for St David's retail development in Cardiff," says Matthew Locke, innovation manager at Bovis Lend Lease. "The boards have survived the Cardiff weather for two years now with no water damage. This material reduces the risk of injury, is easier to use than plywood and will reduce the carbon footprint of our temporary works."

Another approach is that taken by Plastinum Polymer Technologies, which has developed the proprietary Blendymer mechanically-induced process and two new types of plastic, Infinymer and Ultrymer.

Infinymer is supplied in pellet form ready for processing with standard plastic manufacturing techniques (Fig.4). SenterNoven, an agency of the Dutch Ministry of Economic Affairs, evaluated this material and concluded that it should be considered as a new material, rather than waste.

Ultrymer is a high-tech hybrid plastic in which several polymers previously considered incompatible are linked using the Blendymer process. Plastinum says that using the Blendymer technology enables high-performance plastics to be developed to match specific criteria.

Whatever the source of the recycled material or the way in which it is handled, there are opportunities for engineers and designers to incorporate them within their products and processes. The amount of scarce resources saved (energy and oil) and the environmental benefits (reduced landfill and CO2 emissions) would be a good justification, but the marketing advantages can also be significant, with both manufacturers and consumers seeking ways to show that they are behaving responsibly. Washing machines, mobile phone cases, building components and packaging are just a few examples of reuse in an industry that will grow as pressure increases to recycle more materials.

What plastic can be recycled?

What plastic can be recycled?

Why are all plastics not included in our recycling bin?

There are more than 60 different types of plastic in circulation and all have different properties according to their uses. Some are designed for high pressure (fizzy drinks bottles) and some are designed for rigidity (food containers). 

The Materials Recycling Facility accepts just plastic bottles which are mostly made from three types of plastic:

  • PET bottle recycling (clear and blue e.g. squash bottles)
  • HDPE (cream colour e.g. milk bottles)
  • PP (many mixed types e.g. shampoo bottles)

There is a high demand for these types of plastic from companies that reprocess bottles to make new plastic products.

Putting the wrong type of plastic in your recycling bin may mean the load is rejected and could cause damage to the sorting process. We don't collect other types of plastics as there is usually a higher value in the plastics that bottles are made of and the MRF was designed to accept plastic bottles only for recycling.

Why do we not include bottle lids, yoghurt pots and plastic bags?

Bottle lids, yoghurt pots and plastic bags are all made from different kinds of plastic from the plastic in plastic bottles.  These will all contaminate Norfolk's recycling stream.

Yoghurt pots are made from another type of plastic called polystyrene and there are limited outlets for this material.

Due to the contamination effect of the printing ink on plastic carrier bags, the material can only be used for low grade and dark colour applications, such as bin liners.  Many supermarkets accept plastic bags for recycling, or you could try using reusable bags.  

 Where do the plastic bottles go to and what happens to them?

The three types of plastic bottle PET, HDPE and PP are sorted at the Materials Recycling Facility .They are then baled up and sold to companies where they are processed by  bottle recycling machines into new products. Products made from plastic bottles range from plastic garden furniture and bins to fleece jumpers and brand new bottles.

 

You can recycle all plastic bottles including:

  • Plastic Milk bottles
  • Plastic Drinks bottles
  • Shampoo and conditioner bottles
  • Detergent / Washing liquid bottles
  • Fabric softener bottles
  • Shower gel bottles
  • Bubble bath bottles
  • Bleach and other household cleaners

Plastic bottles pile up as mountains of waste

Plastic bottles pile up as mountains of waste

The biggest growth in bottled beverages isn't beer or soft drinks or juices. It's tasteless, colorless and sugarless water. And while that can mean fewer cavities and slimmer waistlines, it irritates people to no end. "Water bottles are now the most recycled container by weight, and overwhelmingly by number." PET water bottles now account for 50% of all the PET bottles and containers collected by recycling. This trend was consistent in all.

The boom in plastic water bottles has people especially frazzled because while the recycling rate is extremely low, the demand from recyclers is actually quite high.

Lots of bottles are not treated and just throw away as wastes . the recycle rate of bottle is relatively very low . But the demand of the recycled bottles is becoming larger and larger .  This is a great opportunity for people of this kind of business to make profit and meanwhile contribute to enviroment protection.

As said above , moutains of waste are waiting to be turned into wealth, PET bottle recycling machine are getting more popular in the future. That is what we are doing now.

Why recycle and the benefit

Why recycle and the benefit

Plastic is one of the most widely used products in the world. We use it to package consumer products, to charge our purchases with credit cards, to carry our food and drink, to build our toys and to even make our clothing! There are over 10,000 different kinds of plastic in the world, and it is so versatile and can be mixed with so many other elements that its uses are limitless.

But plastic takes up about 10% of our total waste stream, and it is composed mainly of the non-renewable resource petroleum. So the more petroleum we burn to make new plastic products, the more greenhouse gases we release into the air. Only 5% of all plastic is recycled, so we need to push for more plastic recycling practices in our daily lives.

What is plastic recycling?

Plastic recycling is the process of reprocessing used scrap and waste plastic into new plastic material. Recycling old plastic products uses 20%-40% less energy than manufacturing it from new.

Plastic is created by combining petroleum or natural gas with oxygen or chlorine. This process requires the burning of large amounts of oil. If we recycled all of our plastics we could reduce our oil consumption and save 25% of our landfill space.

What types of plastic products can be recycled?

The American Society of Plastics has recognized seven different types of plastic and has given each category a number, which can be found on the bottom of the plastic container. The two most recyclable categories are:

Marked “1”

This category contains PET or PETE (Polyethylene Terephthalate) plastics. These plastics include:

  • Soda and water bottles
  • Mouthwash bottles
  • Plastic wrap
  • Peanut butter and other food jars
  • Salad dressing bottles

Our company has the machine to crush and recycle pet bottles and containers. The PET bottle recycling line is becoming more and more popular .

Marked “2”

This category contains HDPE (high-density polyethylene) plastics. These plastics include:

  • Milk containers
  • Trash bags
  • Yogurt containers
  • Liquid laundry detergent containers
  • Shampoo bottles
  • Juice containers

For this type of plastic we offer machine line that can recycle films and bags etc, our PP PE film recycling line  has won great rreputation among our customers.

It’s important to always wash and rinse out your plastic containers before you take them to a recycling center.

And also we have various of auxiliary machines for you to choose too.

What are the benefits of plastic recycling?

Here are some benefits of recycling plastic:

  • Recycled plastic can be made into plastic lumber, which is more durable
  • Reduces greenhouse gas emissions
  • Can be used to make toys, park benches, car parts, drainage pipes and more
  • For every 7 trucks it takes to deliver paper bags, it only take 1 truck to deliver plastic bags
  • Recycled soda bottles can be reused to make filling for pillows and jackets
  • The plastic recycling business creates lots of jobs.
