Thinking inside the Box

Traysrenew ProjectWhile hemp fiber is classically associated with being as a textile fiber such as for t-shirts, there are many other uses. Of course not all hemp fibers are textile grade, such as those that are the stalks from hemp seed crops. Consequently, a European research project is unpacking the properties of hemp into natural, renewable & biodegradable food packaging. And we’re not talking about rough burlap bags or paper forms. It’s a true plastic and is commonly referred to as bioplastic since it’s not derived from petroleum.

The Traysrenew project in the European Union (EU) was a multi-year project involving a consortium of manufacturers drawn from across the supply chain with researchers from Spain and England. The goal was to produce food trays for poultry products that are cost effective, renewable, and higher performance than their conventional counterparts which are made of Polystyrene (PS) or Polypropylene (PP). The food trays would be made from biopolymers which are derived from bast fiber plants including hemp and flax. The poultry sector was chosen due to its high volume, being that it produces approximately 11 million tons of meat annually in the EU, with an average per capita consumption of 50.6 pounds (23 kg) each year.

The interest on this kind of green packaging is being driven by both the industry and consumers. Manufacturers want lower costs and increased shelf life; consumers want fresh and safe food available in addition to products that reflect their values.

Technical challenges

Up to now, the use of biodegradable films for food packaging was considered limited due to poor barrier protection from environmental elements including: oxygen, water vapor, dust, light, and air, in addition to weak mechanical properties. The higher costs associated with the use of these materials has also been an ongoing issue.

Fiber-based hemp composites for packaging relies on both nanofibers as well as a specially derived powder that is mixed with other materials. Using a variety of methods the materials are mixed, compacted and melded — commonly by either heat or by letting the composite mix solidify.

Starting work in 2010, Traysrenew created and tested a thermoplastic tray and lid made of 85% biopolymers with 15% hemp / flax based microfibers. Testing showed this tray met all targeted industry performance standards.

As hemp fiber is known to have anti-bacterial properties, adding hemp to food packaging has the additional benefit of increasing preservation. However, technical details on these antibacterial properties are specifically lacking at the time of this writing.

Project results

The Traysrenew project touts their trays as having a shelf-life at chill temperatures of 10 days, which matches the typical sell-by date for how long poultry is displayed for sale inside a stores refrigerated display case. Poultry is considered to be easily spoilable by grocers, so anything that adds to the shelf life is welcome in the retail trade.

With this project, industry participants touted the economic benefits to manufacturers, the environmental benefits of using renewable and biodegradable packaging as well as the social benefits of increasing demand for fibers grown domestically on local farms.

It’s an open question as to when and if these trays will be adapted by the European food industry, but it’s likely. According to industry association European Bioplastics, a total of 700,000 tonnes of bio-based plastics were produced globally in 2010, and the market is projected to reach 1.7 million tonnes by 2015. 60% of these were used for packaging, making it the largest application of bioplastics. The growth rate for bioplastics is estimated at 22.5% a year.

Portland, OR — CRAiLAR Technologies Inc., which produces and markets CRAiLAR® Flax fiber The Friendliest Fiber On The Planet™, today announced that it has executed a letter of intent (“LOI”) to acquire a European fiber dyeing facility with more than thirty years of experience in the industry. The acquisition, which is subject to the entry into definitive agreements and prior regulatory approval, would establish CRAiLAR flax fiber production for the Company in one of the most prolific flax growing regions in Western Europe.

The facility is currently capable of producing in excess of 250,000 pounds of CRAiLAR Flax fiber per week with room to expand. Under the terms of the LOI, CRAiLAR will acquire the facility by retiring approximately U.S.$1.2 million of the vendor’s debt over a three-year period. Additionally, CRAiLAR will enter into a ten-year lease and option to purchase agreement on the building housing the facility with a renewal option for an additional ten years.

“We are thrilled by the prospect of having complete control of the CRAiLAR production process and, we believe, an immediate path to positive gross margin with no capital outlay,” stated Ken Barker, Chief Executive Officer. “Acquisition of this facility would accelerate our production timeline by six to nine months; eliminate construction risks inherent with a ‘green field’ project; and substantially reduce the capital required to achieve one million pounds per week of capacity. The plant is also is located in an area known for flax growing excellence, thereby providing an abundant source of feedstock, and ties in perfectly with our European flax fiber sourcing initiative.”

The proposed establishment of a CRAiLAR wet processing facility in Europe is in addition to the longer-term plan to establish a fully integrated CRAiLAR facility at the Company’s present site in Pamplico, South Carolina.

Editors note: Demand for natural fiber, especially those bound for automotive composites, is experiencing steady demand. Daimler-Chrysler plans to utilize locally available natural fibers such as Manila hemp, abaca (not to be confused with true cannabis sativa hemp) in the Philippines to meet demand. Daimler-Chrysler uses true cannabis sativa hemp in its Canadian and European production facilities.

Automaker Daimler-Chrysler has approved the use of Philippine abaca for the exterior lining of its class A cars, which include the Plymouth and the Mercedes-Benz, Daimler-Chrysler consultant Dr. Werner Muhlbauer told the Inquirer Tuesday.

Philippine abaca meets the standards of the firm and can substitute for the non-recyclable fiberglass used to line the cars’ chassis, he said.

“Daimler-Chrysler has decided to incorporate Philippine abaca for its composite materials for the exterior lining of its cars. It has the same strength as fiberglass, minus the weight,” Muhlbauer said.

Muhlbauer said he did the scientific testing of Philippine abaca with the help of the Leyte State University.

They are still studying if Philippine abaca can also be used for the cars’ interiors, he said.

“Daimler-Chrysler just wants an assurance that the quality and quantity of Philippine fiber could be sustained in the next five years,” he said. “We hope there would not be too much price fluctuations.”

Abaca fiber was the Philippines’ first top agriculture export.

It is used as raw material for cordage, rope, as well as tea bags.

National Research Council (NRC) technology could help clothe Canadian athletes at the 2010 Winter Olympics in Whistler, B.C. and help pave the way for a range of advanced products made with industrial hemp, such as auto parts and airplane fuselages.

Hemp Plant

Hemp

A valuable crop since ancient time, hemp has been cultured with its seeds as food, and its fibres, strongest in the plant kingdom, for the production of rope, wagon cover, canvas and sailcloth. Hemp thrives in Canada’s cool climate and can be grown without the use of pesticides, fungicide or herbicides. Industrial hemp and marijuana both belong to the same species, Cannabis sativa, but each has been modified to have different characteristics, hemp for long fibres and fast growth, marijuana for its content of the psychoactive drug, THC. Industrial hemp contains next to no THC. In 1938, the cultivation of hemp was banned by Canada and the U.S.; however, in 1998, new Canadian regulations enabled the licensed commercial cultivation of industrial hemp. Present and potential uses for industrial hemp, besides clothing, are numerous and include: fabricated auto parts; biocomposite, geotextile, wood and paper products; foodstuffs; cosmetics; biomass for fuel, heat-insulation, etc. Industrial hemp absorbs carbon dioxide five times more efficiently than the same acreage of forest and can play a role in the strategy to reduce greenhouse gas emissions.

Hemp Fiber Comparison

2. Chinese fibre
3. NRC enzyme-treated fibre

NRC recently entered into a collaboration with Vancouver-based Hemptown Clothing Inc., a manufacturer of hemp clothing that has promoted the idea of using hemp fabric for the uniforms of Canada’s 2010 Olympic team. Under the partnership, Hemptown will work with the NRC Institute for Biological Sciences (NRC-IBS) to commercialize NRC-developed enzyme technology for processing hemp fabric (enzymes are used widely in industrial applications for everything from pulp bleaching to meat tenderizers). The technology promises dramatically improved fibre quality (softer, whiter fabric) using environmentally friendly methods. The collaboration stems from work by Dr. Wing Sung, an NRC-IBS researcher and an expert in the use of enzymes for industrial applications.

“There’s no problem growing industrial hemp in Canada. Canadian companies are also effective in selling the finished hemp products. The problem is that Canada lacks the expertise and technology for processing,” Dr. Sung explains. Indeed, earlier efforts to build a hemp processing facility in Manitoba were unsuccessful. To ensure market success, a processing facility requires a low-cost and environmentally friendly processing technology that produces superior quality hemp fibres. Initial results from the enzyme technology reveal striking improvements in the quality and performance of hemp fibres using this approach. “We are now able to produce hemp fibre of higher quality than that produced in China and Europe,” Dr. Sung says.

Creating Business Opportunities

We would like to help our partner to make an economic impact as soon as possible. Hopefully, this will whet the appetite of other players to jump in and start using the enzymatic approach to process other parts of the hemp plant. With clean strong fibres made available by our process, we can stimulate the development of many different advanced products.
— Dr. Wing Sung, NRC-IBS

China, the world’s leading producer of hemp fabric uses chemical methods for processing, while producers in Europe have begun using cleaner biologically-based enzyme technology. Neither method produces fabric with the same whiteness and softness as cotton. As a consequence, most hemp clothing tends to be blended with cotton, a plant with a long history but which, from an environmental perspective, consumes far more resources than hemp. The goal is to produce hemp fibres superior to cotton in strength, durability, warmth and moisture-absorbance, yet with the same softness and brightness, via a non-chemical process. “We are excited about new possibilities for producing a home-made Canadian hemp-based fabric with the NRC,” notes Jason Finis, President of Hemptown.

Hemp Fiber Enzyme Treatment

The NRC-IBS team made a deliberate decision to work with a commercially-available enzyme rather than starting from scratch (a longer process) and has focused on optimizing the conditions under which this enzyme operates. For example, Dr. Sung has been studying the optimum operating temperature for the enzyme processing. In general, the higher the temperature the higher the activity level, but higher temperatures also mean higher energy costs for producers. Other adjustments have been made to pH levels to avoid damages to the fibres and the processing equipment. Dr. Sung notes that the use of enzymes for processing is well known, however, as this optimization approach demonstrates, improvement is possible. “It’s not a secret using enzymes, but there is still lots of room to establish your own unique opportunity to make the process work faster, better and cleaner,” he says.

Dr. Sung designed the NRC xylanase enzyme (Biobrite), widely used today for the production of bleached pulp, and is candid about the challenges faced by the team. “Environmental benefits are, of course, extremely important but if you are unable to produce something that will save money for the producer, the technology won’t fly.” Time will tell but initial results are encouraging.

Premium Crops Ltd, a specialist UK crop production company, has announced the closure of its hemp and flax processing factory located in North Wales.

The decision results from a combination of several factors, such as recent changes to the EU Common Agricultural Policy and continued delays in the establishment of sustainable markets in the UK for industrial grade natural fibres. However, increasing pressure from a landlord appears to be a major factor.

“We very much regret the decision as we continue to view fibre crops as a medium to long term opportunity, but the economics of maintaining the facility cannot justify further increases in costs at this time,” said a spokesman for Premium Crops.

The factory comprises a complete processing line for the extraction and cleaning of fibre from flax and hemp straw, together with fibre blending facility, fibre and shive baling and dust briquetting equipment. It is the largest facility of its type to have been built in the UK in recent years.

The complete processing line will now be sold off, either as a whole or as individual components, with the intention to remove all equipment by the end of July.

Winnipeg, Manitoba, Canada — Proponents of a hemp-processing factory in Dauphin met with provincial officials Monday to present an updated business plan and secure financial backing.

The Parkland BioFibre hemp factory would process locally grown hemp straw into fibre products.

“We’ve identified the markets for both the bast [long] fibre and the hurd [short fibres],” says spokesman Don Dewar.

“We have prospective customers. One is a major supplier of hurds into the bedding market in Europe. It’s a French company, but it has a Canadian office and is looking at supplying the hurds into North America. The other is a company that recycles cardboard.”

Dewar says the plant would create 20 jobs and bring in $4 million a year for local hemp farmers.

Dewar and the Parkland Industrial Hemp Growers co-op want the provincial and federal government to kick in about $6 million, which would be paid back. Dewar says the provincial government is on board, but the federal government has no yet committed; he hopes to meet with officials from both levels of government within the next couple of weeks.

Dewar says they will not solicit investment from the general public until they develop a market and get support from governments and banks.

Burdekin district, Australia — It’s not every day you come across a grower whose crop will be harvested by a Japanese firm to go into computers and mobile phones.

But Andrew Saunders is such a farmer. He’s growing kenaf, a fibre crop, similar in appearance to industrial hemp.

Andrew was one of nine cane farmers in the Burdekin district who put his hand up to grow kenaf when he was told a foreign firm was keen to contract growers in the area.

And so far, everything is going well. In five months the crop is towering at two point five metres, and is expected to be harvested after Easter.

Depending on which way you look at it, Andrew is one of the more fortunate cane farmers. Having only been in the game for seven years, he’s never known a season with good sugar prices. This has encouraged him to try new things on a property with ample water, good soil and plenty of sunshine.

And he hasn’t stopped with kenaf — Andrew is also experimenting with companion planting soybeans with cane, to increase soil nitrogen and reduce fertiliser inputs.

He’s eagerness to experiment goes beyond the crops. His true passion is managing the best soil possible, leading him to use unconventional, but true and tried methods.

It’s this part of farming that fuels his love of primary production in an environment that’s unpredictable — and still returning low sugar prices.

Offering Enhanced Occupant Safety, Cost Savings and Weight Reduction

By Lear Corporation

Gothenburg, Sweden — Lear Corporation (NYSE:LEA), one of the world’s premier automotive interior suppliers, has launched two new polymer materials to be used in some of Lear’s future offerings of interior trim products: door panels, pillars and trunk trim. With properties promising optimized occupant safety and cost saving potential, these ultra-lightweight and recyclable polymers could literally save vehicle manufacturers both weight and money. Because they are composed of natural fibres that are replenishable, the two polymers are also environmentally friendly.

The two innovative polymers, natural fibre acrylic and natural fibre polypropylene, have been developed at Lear’s Manufacturing Operation Division’s development center in Ebersberg, Germany, where materials development focuses on vehicle safety and weight reduction. Lear made the announcement on the new polymers at the VISE & VIBEX 2000.

“With these two new polymers, Lear is addressing key material needs for European vehicle manufacturers, who want to reduce weight while contributing to passive safety,” said Randall Carron, President — International Operations for Lear Corporation.

Natural Fibre Acrylic for Door Trim, Package Trays

This patent-pending natural fibre acrylic polymer has been developed for automotive door panel trim, package tray and trunk applications. A so-called “modular binder system” allowing stiffness and impact resistance to be varied according to need offers extreme flexibility for customers. The exceptionally lightweight properties of the natural fibre acrylic polymer also could make it suitable for a range of other automotive interior applications in the future.

“In our extensive testing we have reached a record low weight of 1300 g/m² — a weight savings of greater than 40% when compared to conventional injection molded substrates,” said Armin Schwaighofer, Material Development Engineer, Lear’s Manufacturing Operations Division in Ebersberg.

“The bending strength of this polymer has proven to be very high, which puts this polymer among the very best in the market right now. The fact that the material consists up to 70% of plant that regrow makes it an environmentally friendly way to use natural resources,” Schwaighofer added.

Selected after months of research, this unique formula of plant fibres and acrylics also offers an improved environment for production workers compared with glass fibre-based polymers.

Natural Fibre Polypropylene for Door Trim, Trunk trim

Natural fibre polypropylene is made from plants that can be regrown that are combined with polypropylene. In this natural fiber, Lear replaced the flax fibre with kenaf, hemp and jute. Additional improvements in mechanical properties were achieved with the use of coupling agents that improve the chemical bonding of fibre and polypropylene. This new material from Lear has superior elasticity, providing high impact resistance. This new “elastic” environment could mean improved occupant safety by eliminating potentially sharp edges caused by conventionally brittle panels that may fracture during an accident.

“Broken interior panels in accidents can sometimes be serious. Our tests have shown that, in an accident, interior door panels furnished with our natural fibre polypropylene are more ‘impact friendly,’” said Ulrich Probst, Vice President and General Manager, Lear’s Manufacturing Operations Division in Ebersberg.

Significant cost savings are achieved through the thermoplastic properties of the polypropylene, which allow the material to be reheated. A one-step process for manufacturing is possible whereby the natural fibre polypropylene is covered with the actual surface material in just one step.

Lear Corporation, a Fortune 150 company headquartered in Southfield, Michigan, USA, is one of the world’s largest automotive suppliers, with 1999 sales of $12.4 billion. The company’s world-class products are designed, engineered and manufactured by more than 120,000 employees in over 300 facilities located in 33 countries.
