Abstract
A biodegradable packaging material and a method of making the same are disclosed. The packaging material is mainly made of beeswax and shellac, and does not contain plastic, fabric or paper layers. The goal is to reuse beeswax waste from residential and commercial honey farms, provide a natural biodegradable alternative to plastic containers and packaging, and to maintain the desirable properties of such containers.
Description
Cross Reference to Related Applications
The present application claims the benefit of priority from U.S. provisional patent application No. 63/374,706, filed on 6 at 9 at 2022, the disclosure of which is incorporated herein by reference in its entirety.
Technical Field
The present application relates generally to natural materials suitable for use in the manufacture of biodegradable containers and packages, and in particular to articles comprising beeswax and methods of making the same.
Background
Plastic is one of the most widely used and least expensive materials in the world today. Plastic was originally developed to some extent to alleviate the limitations imposed by the scarcity of natural resources, and plastic has become popular because of its light weight, low cost of production, and ability to be molded into virtually any shape. Plastic containers are commonly found in the beverage and food, cosmetic and pharmaceutical industries.
Over time, consumer opinion of plastics becomes less aggressive. There are several factors that affect, including the increasing awareness of the hazards of phthalate and paraben additives and related chemicals, environmental problems such as accumulation of disposable plastics in landfills and oceans, and insufficient plastic recycling opportunities.
This transition has made it necessary to explore environmentally friendly plastic alternatives that provide similar or better performance. For example, natural materials such as wood, bamboo, and cardboard are renewable and degradable. However, such materials still have a significant environmental footprint due to the energy required to plant the raw materials and to manufacture and transport the goods made from such materials. Other natural materials that have recently been developed for use as plastic substitutes include mushroom-based packaging for replacing polystyrene foam, seaweed-based packaging, converting grape waste into imitation leather, and the like. The reuse of organic waste from other industries and the conversion thereof into effective plastic replacement materials is of particular interest, as it has the further advantage of reducing the energy and resources involved in recycling.
Beeswax is a natural wax produced by worker bees that is secreted by the wax producing glands of the abdominal node of bees. The wax is initially transparent and colorless, but becomes opaque and yellow or brown after the addition of pollen, pollen oil and propolis. Bees shape bees into scales for building honeycombs that store honey, young honeycombs that store bees eggs, and burr combs that provide structural support to the honeycombs. About 100 tens of thousands of scales are required to produce about one kilogram of beeswax. It is estimated that one kilogram of beehive beeswax is sufficient to store 22 to 30 kilograms of honey. When beekeepers extract honey, the wax caps of each honeycomb cell are cut away, and the unwanted burred and young honeycomb is either discarded or refined for further use.
Beeswax is edible and, like vegetable waxes, has negligible toxicity. It is insoluble in water and resistant to hydrolysis. Beeswax consists essentially of long chain esters of fatty acids and alcohols. Long chains may be described as carbon chains of at least 12 carbons in length. The components of beeswax include palmitate, palmitoleate, cerotic acid and oleate of C 30-C32 long chain fatty alcohols. Beeswax has a melting point of about 64.5 ℃ (148°f), but becomes soft and pliable between about 35 to 40 ℃ (95 to 104°f) and brittle below 18 ℃ (64°f).
In 2020, global yields of beeswax exceeded 62000 tons. The cosmetic use of beeswax requires high quality beeswax that is pure and free of propolis. Current industrial uses of beeswax include use as lubricants, coatings and wax castings. Beeswax is also used in the manufacture of candles, although as a cheaper alternative, beeswax may generally be combined with or replaced by paraffin. About 20% of the commercially produced beeswax is discarded as waste.
Thus, there is a great need in the industry for acceptable natural organic materials that do not pose environmental problems. There is also increasing interest in reusing natural waste from other industries, such as beehive waste beeswax from honey farms. The present invention aims to meet this need.

Disclosed herein are embodiments of a method for producing a beeswax-based product. Raw beeswax, which was not processed, was melted into a liquid form in a double pot. Liquid beeswax is removed from the heat source, an amount of shellac is added and mixed into the liquid beeswax to form a liquid composition. Optionally, activated carbon powder is added and mixed into the liquid composition. Optionally, the liquid composition is filtered to remove any solid impurities. The liquid composition was poured into a mold and left at room temperature to cure and dry. The solid composition is removed from the mold and may optionally be further coated with an insect gum layer.
In some embodiments, the weight ratio of shellac to beeswax in the liquid composition is about 0.5 to about 99.5, about 1 to about 99, about 1.5 to about 98.5, about 2 to about 98, about 2.5 to about 97.5, about 3 to about 97, about 3.5 to about 96.5, about 4 to about 96, about 4.5 to about 95.5, or about 5 to about 95.
In some embodiments, the activated carbon powder comprises 0%, up to about 1%, up to about 2%, up to about 3%, up to about 4%, or up to about 5% by weight of the liquid composition of shellac and beeswax.
In some embodiments, the liquid composition has a cure and dry time of about 4 hours, which is not intended to be limiting.
In some embodiments, the coating of shellac is added at a weight percent of 0%, up to about 0.5%, up to about 1%, up to about 1.5%, up to about 2%, or up to about 2.5% of the total weight of the composition.
The molds used to prepare the products from the compositions described herein may include commercially available or custom silicone molds, or molds made from other materials, which are not intended to be limiting. The products prepared from the compositions described herein may include can bottoms and can tops, and may further include can bottoms and can tops that may be sealed by a screw mechanism, which is not intended to be limiting.
As described in the examples below, various evaluations were made of the function of the compositions disclosed herein:
Example 1: durability of
Combinations of beeswax and shellac and combinations of beeswax, shellac and charcoal have been used to form cans having a bottom and a screw top. These cans were opened and closed more than 1000 times, and no change in shape or form or damage to the threads was observed. These cans were dropped from a height of 2 meters (about 6.5 feet) and no change in shape or form or damage was observed.
Example 2: heat resistance
Combinations of beeswax and shellac and combinations of beeswax, shellac and charcoal have been used to form cans having a bottom. These cans were microwave heated at full power for up to two minutes without observed shape or form changes or damage. The combination of shellac and beeswax maintains a similar melting point as beeswax.
Example 3: water resistance
Combinations of beeswax and shellac and combinations of beeswax, shellac and charcoal have been used to form cans having a bottom and a screw top. These cans are partially or completely filled with water. No leakage was found after inverting the can, indicating that the seal was watertight and airtight. The cans partially or fully filled with water were stored for up to 12 months, and no change in the volume of the liquid or change in the shape or form of the cans was observed, indicating water resistance over a period of at least one year.
Example 4: decomposition of
Beeswax and shellac are animal waxes and may take a short two week or two month period for decomposition in a compost bin, garden or landfill. The combination of beeswax and shellac and embedded seeds were buried in the garden for two months and showed similar decomposition rates. As the combination of beeswax and shellac disintegrates, bees are attracted to the area where the combination is buried, and as plants grow from the seeds, more pollinators are attracted to the area where the combination is buried.
