Is molded pulp biodegradable

Yes, molded pulp is biodegradable, typically decomposing within 90 days in commercial composting facilities.

Made from Natural Materials

One of the best examples of environmentally friendly material usage in our everyday life is molded pulp. This safe language is often constructed of fibers, such as recycled cardboard or newsprint, which means it is biodegradable. In a commercial composting facility, these products usually break down within 90 days, while plastic can take up to 1000 years to degrade in a landfill . In the packaging industry, molded pulp is used for protective packaging, egg cartons, and food service trays, which is a clear reduction in waste. In the retail industry, many companies now use molded pulp to package their electronics and appliances, which they say are shock absorbent and waterproof.

Thus, they were attracted by molded pulp to reduce their ecological footprint because it is not only biodegradable but also uses less energy than plastic. According to Molded Fiber Glass Tray , molded pulp uses about 40% less energy to produce than traditional plastics. This material has practical application in home gardening. Molded pulp seed starter pots are used by gardeners because they can be planted directly into the ground, preventing the “root lethargy” that usually occurs when gardeners transplant plants. It is not necessary to throw plastic pots, which will reduce the waste of such items. Finally, molded pulp is finding uses in educational institutions for art projects and real-world demonstrations that help students to learn about sustainability and responsible material usage.


No Chemical Additives Required

One of the most unique and long-standing materials in the manufacturing world is molded pulp, which is highly valued for its natural composition. In contrast to plastics, which appear to be widely produced, molded pulp is not subjected to synthetic compression. Molded pulp manufacturing implies the conversion of recycled paper products – such as newspapers, vegetables, cartons, and others – through a pulping machine in the presence of water and mechanical action to produce a fibrous mash . Moreover, the pulp is set in a mold, which creates an adequate shape of a final product. The production of molded pulp does not involve synthetic chemicals or synthetic polymers meaning that no released or disposed pollutants are amassed, which is a vastly added benefit to petrochemically produced plastics .

The practical implementation of molded pulp is widely observed in many food packaging companies, which produce containers and trays. By not having to add any chemicals, food manufacturers can remain at peace knowing that no contamination may have taken place. In addition, the absence of chemicals helps containers meet organic certification standards, which mandate no leaching of synthetic compounds into food. The organic food market today amounts to more than $95 billion, and using molded pulp helps companies maintain the organic purity of food . In terms of costs, using chemical materials would apply an additional burden on the manufacturing process .



One of the most contradicting benefits of molded pulp is its water solubility. This feature has a big impact on the biodegradability of this material. Molded pulp dissolves very quickly when affected by natural phenomena. For example, if the pulp pot is left outside in the rain, it would start to “disappear” because the water dissolves the pulp . Instead, styrofoam, and many kinds of plastics and other connective compounds are water-resistant, so they can exist in the nature for hundreds of years, not changing their structure. For example, potteries and gardening stores often sell plants in a pulp pot, so it can be put directly in the soil, where it would dissolve in a few weeks due to the moisture and rains, getting into the composition of the soil, but not leaving any harmful “skeletons” like plastic pots, which are not that likey to be destroyed in the soil from which the pot becomes removed by definition.

Another common water-soluble application of the molded pulp is in the cases of eco-friendly detergent. In attempt to reduce the amount of plastic, traditional packing material for liquid means gets replaced with molded pulp package, which dissolves quickly in the washing machine when the detergent needs to be released, and poses no threat to environment or the health of the customers. This is one of the great benefits to attract the environmentally cautious customers, as many of them try to reduce the usage of plastic in their households and everyday lives. And besides, people trade the money they would spend on the molded pulp itself for the price of the dumping all of the making waste the company has to take care of.

Composts Well

Molded pulp is a material that is highly appreciated due to its ability to compost effectively. This means degrading into soil. The soil where the pulp was absorbed becomes healthier, prolonging the life of the garden and preventing the trash from going to landfills. In comparison to the conventional plastic, pulp will go back to the soil, while plastic items, which have a greater disintegration time will stay in the landfil even after the specific object has been already destroyed.

The items made this way and often used or gardeners are the seed trays. After the seeds and the plaits grow and it is possible to move them in soil, the trays can be buried, enhancing the soil structure. The trays can be composted avoiding the need to be removed and destroyed, saving time, labor and landfill space. The composting facilities appreciate the material as well since it disintegrates quickly, wih 2 and 6 months required for the composting characteristics depending on the items . Restaurants and cafes use molded pulp products as well. This decreases the expenses of the equipment, as it can be composted along with the food after it has been used. The decrased volumes of undecomposable wastes provide an additional benefit due to the reduced charges that were implemented for each ton of solid wastes . Finally, the use can be extended to gastronomic events, since the party items can be thrown away after being used, without the neccissity of damaging the environment with the non-decomposeble.
