What is tPLA and cPLA?

To understand cPLA and tPLA, you have to know a little about PLA, or polylactic acid.

PLA products are bio-based and biodegradable alternatives to petroleum-based plastics. They are manufactured from any fermentable sugar, usually corn. PLA provides a much-needed eco-friendly alternative to petroleum-based plastics. For a deeper dive on PLA, check out our PLA Guide.

PLA is a comparable, environmentally-friendly alternative to traditional plastics. However because its made from corn and not oil-based materials, rigidity and heat resistance isn&#;t as high as that of conventional plastics. Conventional plastics come in a wide variety of numbered types with different properties for various applications.

This is why cPLA and tPLA were developed.

These two variations on PLA strengthen PLA&#;s weaknesses while offering the same benefits.

• cPLA = C

  rystallized PLA

  .

  It&#;s processed by applying high pressure and heat to PLA, chalk, and other biodegradable and bio-based additives. This causes the material to crystallize, resulting in a harder product that&#;s less susceptible to heat degradation.

  CPLA lids

  are commonly used for coffee cups.

• tPLA = T

  alc-injected PLA 

  is

   created by combining the two materials at a ratio usually around

  70% PLA

  and

  30% talc

  . Talc is a natural mineral with very high thermal stability that helps PLA mold into harder more heat resistant materials. For that reason,

  tPLA utensils

  are a common eco-friendly option. Talc is not renewable but it is

  an abundant natural resource

What are the environmental benefits of tPLA and cPLA packaging products?

Like PLA, these two materials require 65% less energy to produce than traditional plastics. They also compost completely in industrial composting facilities.

1.  Biodegradable &#; PLA meets international standards for biodegradability as it is a plant based material. Both tPLA and cPLA will naturally degrade over time. Like PLA, both varieties will decompose faster in a commercial composting facility.

2. Compostable &#; tPLA is 100% compostable in 3&#;6 months in a commercial facility. cPLA is 100% compostable in 2&#;4 months in a commercial facility.

3. No toxic fumes &#; Unlike traditional plastics, these two options won&#;t emit toxic fumes during incineration.

The food packaging benefits of tPLA:

• Can withstand temperatures up to 200°F
• Reusable and dishwasher safe
• Certified compostable by BPI (Biodegradable Products Institute)

The food packaging benefits of cPLA:

• Can withstand temperatures up to 180°F

• 100% renewable and bio-based

Are tPLA or cPLA food packaging products right for my business?

All about PLA & CPLA &#; compostable bioplastics made from plant starches

At Vegware, we manufacture our catering disposables from a variety of plant-based materials. We use paper, board and pulp, but the big difference is that we don&#;t use conventional plastics.

Our cups still need to be leakproof, and our clients still want clear windows, so we use compostable bioplastics &#; compostable materials derived from plant sources.

What is PLA?

PLA is a compostable bioplastic derived from plant sugars. PLA stands for polylactic acid. It can be made from any sugar, such as corn starch, cassava, sugar cane, or sugar beet. NatureWorks is the world&#;s largest producer of PLA, and a key partner to Vegware. Industrial corn is the primary source crop at the moment, but NatureWorks are working actively to diversify feedstocks.

NatureWorks refer to their PLA under the Ingeo brand, and offer full information online on how it is made, and end of life options.

How PLA is made

Corn plants are milled to extract the starch, in the form of glucose. The glucose is then fermented to produce lactic acid. Next up, a chemical process transforms the lactic acid into a polymer, which can be made into pellets, known in the industry as resin.

Just like a conventional plastic resin, the PLA pellets can be used in a variety of ways &#; extruded into a sheet or film, injection moulded, cast into sheets, or spun into fibres. PLA has a huge range of applications, but at Vegware we use it for:

• Moisture resistant linings in paper cups & bowls
• Clear cold cups, salad containers, sauce pots
• Lids for a variety of products
• Clear windows in sandwich wedges, salad boxes and catering trays

PLA pellets ready for a variety of uses

CPLA &#; crystallised PLA for higher heat use

PLA has a low melt point, so is best for cold use up to around 40ºC or 105ºF. Where more heat resistance is needed, such as in cutlery and coffee cup lids, we use a crystallised form. This involves adding chalk to the PLA to act as a catalyst, and then rapidly heating and cooling the PLA resin during production. The result is a product which is heat stable to 90ºC or 194ºF. Vegware&#;s CPLA products are suitable for industrial / commercial composting.

CPLA is crystallised PLA, for hotter uses like coffee lids or cutlery

Corn for food, feed AND industrial uses

The industrial corn used to make NatureWorks Ingeo PLA is non-food-grade, so it is not competing with food for human consumption. The whole plant is harvested, and every part of it is used. The plant-based proteins are used to make animal feed, and the starch has many industrial uses including: in airbags, corrugated cardboard, recycled paper, pharmaceuticals, condoms, and making PLA!

Read more information on food and bioplastics from NatureWorks, the world&#;s largest producer of PLA.

All of the corn plant is used, creating animal feed and many industrial products.

PLA &#; which waste stream?

Vegware&#;s compostable catering disposables can biodegrade in under 12 weeks in commercial composting, which provides the perfect balance of microbes, moisture and warmth.

Where there is no access to industrial composting, used Vegware should be put in general waste. Vegware&#;s takeaway packaging is made from plants, not plastic, using lower carbon, renewable or recycled materials, and these sustainability benefits still apply no matter what happens to them after use.

• Used Vegware should NOT be placed in standard recycling bins which collect paper and plastics as those materials go to a different type of sorting facility. Another reason is that food waste negatively impacts the quality of mechanical recycling &#; the same applies to any used foodservice disposables, even those made from "recyclable" plastics.
• General waste goes to either incineration or landfill.
• In landfill, studies have shown that compostable packaging is inert and does not give off methane. PLA does not break down in landfill, but neither does anything else.
• Please do not litter &#; compostable packaging is not expected to break down when discarded in the environment, and is not a solution to marine pollution.
• Home composting conditions vary with the skill of the householder, so we don&#;t make any claims there, but there have been successful trials using hot compost bins.
