Green, Eco-friendly, or Sustainable,  is that the question?

Here is a short lesson on the green, eco-friendly and sustainable materials that the new wave disposables are being produced with....what ever you choose to call it.


Starch:
Starches have been widely used as thickeners for the food industry for many years. The primary sources of food starches are corn, wheat, potato, maize and tapioca.

Maize Starch:
The starch-based biodegradable environmentally friendly tableware is made of maize starch through the appropriate technology, comparing with the disposable tableware what made of paper or plastics, the starch-based tableware has advantages as follows: 
Firstly, harmless to the human body - -Because it is made of maize starch, not including any harmful material to human body, can rest assured to long run.
Secondly , pollution-free--The products are made of maize starch, can completely be biodegraded to be carbon dioxide and water. Not harmful to soil and air, and will not cause white-pollution.
Thirdly, save resources - -The maize starch is inexhaustible renewable resource, but the tableware made of paper or plastic takes a large number of timber and petroleum chemical products. Starch-based tableware can save a large number of petroleum resources and forest reserves to regard maize starch as raw materials     
Fourthly, high quality - - Starch products have good dense weaving, are able to bear water, oil, and defend infiltrating. In the meantime, they also have the good performance on bearing high and low temperature, suitable for the refrigerator to freeze and refrigerate, keep the food fresh, heat food with microwave oven, etc.


Rice Starch:
Rice starches are the little known secret of the starch world, comprising a very small percentage of the total starch usage. Don't be fooled by the fact that rice starches are not as common as the other starch sources. They have many unique attributes that make them some of the most interesting starches in the food industry. Rice is the most widely consumed basic foodstuff in the world. Each year over 500 million tons of rice is harvested, providing sustenance to many countries and people throughout the world. The keys to the unique properties of rice starches are found in its many varieties. Due to different climates, soil characteristics and cultures, over 240,000 registered varieties of rice exist in the world. This variety leads to a wide range of rice starches with many different characteristics including: different starting gelatinization temperatures, textures, processing stabilities and viscosities. This means that a natural "native" rice starch may provide all the stability that a food processor will need without having to resort to chemical modifications.

Bamboo:
The fastest growing woody plant on this planet: some species can grow up to 3 feet per day! Produce 4 to 5 times more biomass than felled trees for wood production. Bamboo is one of the strongest building materials in the world. (Bamboo tensile strength is 28,000 per square inch versus 23,000 for steel!) A critical element in the balance of oxygen and carbon dioxide in the atmosphere Soil conservation tool. Its anti erosion properties create an effective watershed. It will decompose in 90 days in your backyard! And in 3 days in a compost pile. It decomposes in 14 days in a lake or river and the fibers can be eaten by the fish!
  • Annually renewable, rapid growing plant.
  • Low energy and no chemicals used in its conversion from starch to our final products.
  • Using sugar pulp starch, reduces waste in the sugar industry as one tonne of refined sugar results in two tonnes of sugar pulp.




Bioplastic:
Bio plastics are often confused with what is traditionally referred to as "biodegradable plastic", which are plastics derived from petroleum such as polyethylene and formulated with heavy metal initiators. These plastics are degraded by exposure to light or oxygen but this is not a microbial degradation process and will not take place in a commercial composting unit

Biopolymers:
FACTS ABOUT THE BIOPOLYMER USED IN BIODISPOSE CUTLERY:
Made from corn, a renewable material.
Biodegrades in microbe active environments in 150-180 days.
It is normally broken down to carbon dioxide and water.
Resist temperatures up to 350 F.
Does not change in appearance or color.
Flexible and stronger than plastic cutlery. 
 Made from renewable natural sources like sugar and corn . It is biocompatible and therefore can be implanted in the body without causing inflammations.
Non toxic product.

Category: biopolymers, made from natural sources like sugar. More than 100 different monomers can be combined within this family to give materials with extremely different properties.They can be either thermoplastic or elastic materials, with melting-points ranging from 40 to 180C.

Disposal: It biodegrades in microbe active environments in 5-6 weeks.
The action of some enzymes produced by microbes soluble PHB which is then absorbed through the cell wall and metabolized.

PHB is normally broken down to carbon dioxide and water when degrade conditions. In absence of oxygen the degradation is faster, and methane is also produced.
PHB is not degraded in biologically inactive systems such as sanitary landfills.

Polycaprolactone is a biodegradable thermoplastic polymer. Although not produced from renewable raw materials, it is fully biodegradable. Polycaprolactone has good water, oil, solvent and chlorine resistance. It has a low melting-point (58-60 C) and low viscosity, and it is easy to process. It is used mainly in thermoplastic polyurethanes, resins for surface coatings, adhesives and synthetic leather and fabrics. It also serves to make stiffeners for shoes and orthopedic splints, and fully biodegradable compost bags, sutures, and fibers.

Disposal: Fully biodegradable.The low melting-point makes the material suited for composting as a means of disposal, due to the temperature obtained during composting routinely exceeding 60 C.

Degradation time is very short. PCL is mixed with starch to obtain a good biodegradable material at a low price.The mix has been successfully used for making trash bags.

PCL

PCL is degraded by hydrolysis of its ester linkages in physiological conditions (such as in the human body) and has therefore received a great deal of attention for use as an implantable biomaterial. In particular it is especially interesting for the preparation of long term implantable devices, owing to its degradation which is even slower than that of polylactide.

PCL is an Food and Drug Administration (FDA) approved material that is used in the human body as (for example) a drug delivery device, suture (sold under the brand name Monocryl or generically), adhesion barrier and is being investigated as a scaffold for tissue repair via tissue engineering.

A variety of drugs have been encapsulated within PCL beads for controlled release and targeted drug delivery which have been peer reviewed. Biodegradable plastics are a form of plastics derived from plant sources such as hemp oil, soy bean oil and corn starch rather than traditional plastics which are derived from petroleum. This is regarded as a much more sustainable activity, as it relies considerably less on fossil fuel imports and produces less greenhouse emissions,between 0.8 and 3.2 tons of carbon dioxide less per ton of biodegradable plastics compared to the same weight in petroleum-based plastics. Many biodegradable plastics are truly biodegradable and will degrade in commercial composting units. Some biodegradable plastics will even biodegrade in the less aggressive conditions of a home compost heap. However, biodegradable plastics can also be formulated to be durable.

Polylactide Acid:
Is a transparent biodegradable plastic made from natural resources. It not only resembles conventional petrochemical mass plastics (like PE or PP) in its characteristics, but it can also be processed easily on standard equipment that already exists for the production of conventional plastics. PLA and PLA-Blends generally come in the form of granulates with various properties and are used in the plastic processing industry for the production of foil, moulds, tins, cups, bottles and other packaging.

It resembles clear polystyrene, provides good aesthetics (gloss and clarity), but it is stiff and brittle and needs modifications for most practical applications (i.e. plasticizers increase its flexibility).

It can be processed like most thermoplastics into fibres, films, thermoformed or injection moulded.

Used for compost bags, plant pots, diapers and packaging.

Category: Biopolymers

Products: Compostable bag

Processes: Most conventional plastic processes like:
Blow moulding, injection moulding, extrusion, vacuum forming, fiber spinning

Environmental notes: Lactic acid can be obtained on the basis of renewable starch containing resources (e.g. corn, wheat or sugar beat) by fermentation, or by chemical synthesis of non-renewable resources.

Disposal: If composted properly it takes 3-4 weeks for complete degradation.
The first stage of degradation (two weeks) is a hydrolysis to water soluble oligomers and lactic acid. The latter, as a naturally occurring substance, is a rapid metabolisation into CO2, water and biomass by a variety of micro-organisms.

 This is all pretty new to me and I don't think I can add much to these descriptions but if you really have a burning question email me at janycegranoff@hotmail.com and I will try to hunt down the answer.
