Used Carpet



Most of the carpets are petroleum-based product. It includes those made from synthetic materials such as acrylic, nylon, and polyester and are backed with latex, polyvinyl chloride (PVC) or polyurethane. According to the data provided by www.informinc.org, every year there are 4 billion pounds of carpet being discarded in the United States. Owing to its bulky property, carpet poses waste management problems because it consumes enormous amounts of landfill space. Incineration of discarded carpet is also not a recommended method because it releases toxic chemicals, including dioxin, into the air. All these facts make carpet recycling a must.

As mentioned earlier, carpet is bulky. Therefore, at the beginning stage of carpet recycling, a baler or baling machine is usually used to compact these bulky used carpets into bales before shipping to carpet recyclers to work on the recycling process. And in order to well compact such bulky and heavy carpet, you will need a heavy duty balers to help you achieve the ideal baling effect.

SINOBALER recommends our Heavy Duty Dual Ram Baler for compressing used carpets into dense, regular shaped bales. This baler series are designed with high press force, from 80tons to 200tons, built in a heavy duty way with high strength, and features dual ram structure.

There are two standard chamber sizes available, which are 1100 x 700mm (43” x 28”) and 1520 x 760mm (60” x 30”). Considering carpets are bulky, it is suggested to go with 1520 x 760mm (60” x 30”). Bigger chamber size means wider feed opening which can make loading more convenient and efficient. As for what compressing force you should choose, it largely depends on your bale weight requirement and budget. Generally speaking, for machines with the same chamber size, the higher the compressing force, the higher the bale density will be. Higher bale density enables you to load more weight into containers and thus save more on shipping cost.

If the standard models cannot meet your requirement very well, customization is always available to tailor a machine that best suits your specific baling needs. Contact us today for your baling solution.

How to deal with Used Drums or Barrels?

Colored steel drums
It is common to see steel drums or steel barrels around us in life.  Such cylindrical containers are generally used for transportation and storage of liquids and powders.  Many drums have a common nominal volume of 208 litres (55 US gallon), measuring just under 880mm (35”) tall with a diameter just under 610mm (24”). 

Regardless the drums were used to contain dangerous chemical or other harmless liquids or powders, storing the drums after their purpose has been served will always be a problem because empty drums tend to become massive containers that take up a lot of space.  For temporarily storage, you can simply just stack it up; but after a while, you will surely run out of space for these drums.

So how will you handle the disposal of drums? Used drums are not like any day-to-day end of used products which can be easily thrown away.  Such large drums are usually handled differently due to its size, as well as the residual material left over in the container which may be considered hazardous.  A waste may be considered hazardous if it is ignitable (i.e. burns readily), corrosive, reactive (e.g. explosive), or extraction procedure (EP) toxic.  Waste may also be considered hazardous if it contains certain amounts of particular chemicals.

A good solution for handling such kind of used drums is to use a Drum Crusher (also known as barrel flattener, drum press, or drum crushing balers) to flatten the drums as thin as three inches high.  This crushing baler can flatten almost any kind of metal containers, drums, or barrels, up to a full 220 litres (58 US gallon) size.  This baling machine is also equipped with Liquid Drainage Channel, which will efficiently drained the residual liquid in the drums out of the baler to keep your recycling area clean and safe.

One drum crusher can compact on average 60 pieces of drums per hour, and only require just 1 person to operate.  So with a volume reduction of almost 85%, and residual material drained, the flattened drums can now easily stockpile on pallets and move to a steel mill for recycling as per your country’s regulations.


Maybe you will feel purchasing a Drum Crusher is slightly costly during your initial budget planning.  But your return on investment is ensured if you choose a good quality machine, the drum crusher will be able to help you to maximize your storage capacity, as well as reduce your transportation cost.  Therefore, all these savings will be able to make your investment worth its while in no time.

Tyre Recycling Technology in Australia


In current day and time, car is an indispensable transportation tool in everyone’s day to day life.  Each year, more than 40 million tyres in Australia reach the end of their working lives.  As such, the volume of waste tyres had become a concern to the society as only a quarter of these waste tyres are recycled whereas most will end up into landfill.  This not only takes up a lot of space, tyres are also know to leach harmful chemicals into the environment; cause fires; and provide a perfect breeding ground for pests like mosquitoes and rats.

Australia Advanced Manufacturing Cooperative Research Centre (CRC) has published a new technology on recycling waste tyres in 2011. Since then, this new technology had significantly helped to reduce the number of used tyres being sent to landfill or illegally dumped, and avoids long term land contamination due to the disposal of tyres in landfill, as well as fire risks caused by stockpiled tyres.  As you know, once a tyre pile catches fire, it is very hard to extinguish, and may continue to burn for days with black fumes visible for many miles.

This new technology was jointly developed by Melbourne company VR TEK, Deakin University and CSIRO. It is well recognized by the Federal Government, and was cited as one of the example of how innovation was helping to build a sustainable future for Australian companies and jobs for Australian workers.

In the past, shredded tyres could not easily be recycled due to its metal content. But with this new technology, the new patented process is able to turn used tyres to high quality rubber powders free of metal contamination, for redevelopment as new products, by using highly efficient mechanical segmenting method. The rubber crumb produced by this new process is even cheaper than virgin rubber.

A number of Australian companies have already started using this new technology to recycle waste tyres. They collect tyres from different sources and then process into range of rubber granules, chips, crumbs, or fine powders, which are then used for a variety of innovative applications, such as athletic tracks, children’s playgrounds, brake pads, new tyres, and many more.

So what exactly are the processes?  Following are the simple 5 steps:

– Tyre recycling companies collect the end-of-life from various locations, and transport them to their designated facility for processing.

– Tyres are sorted by size and composition for further processing. Tyres suitable for recycling are being separated and brought to production line directly.

Tyres are shredded in preparation for further processing, and then further reduced in size by a granulator.

The steel at the centre of each tyre is being removed and reused. Some factories can recycle over 3,000 metric tonnes of steel as a result of this process.  The steel free tyre granules are then stored separately.

– The tyre granules will be grinded into finished product depending on the particle size required. For example, buffings and shred (which can be used in matting, sport surfaces and turf), granules and chips (which can be used in horse arenas and asphalt), crumbs and powders (which can be used in road sealing, adhesives and paints), large shred tyre chips (which can be used in civil engineering and fuels).

By improving our knowledge and technology, understand how valuable resources are recovered and returned back into the circular economy and making changing to our purchasing decisions, we can all contribute to a more positive environmental future. :)
