Abstract
A method for forming biodegradable material comprising: collecting and granulating an aggregate, preparing a binding suspension, dispersing the aggregate in the suspension, moulding the mixture, eliminating a flow agent from the suspension to allow the remaining components to cohere and form the final material. The aggregate may be a calcium carbonate based material. The binding suspension may be made of a binding agent and a flow agent. The binding agent may be biodegradable fibre or fibril based material which may be cellulose based. The flow agent may be water. The calcium carbonate aggregate may comprise waste by products such as egg shells, sea shells, and remains of shellfish.

BIODEGRADABLE MATERIAL FROM A RAW CALCIUM CARBONATE BASED MATERIAL AND A BIODEGRADABLE FIBRIL OR FIBRE BASED BINDING AGENT
This invention concerns generally to a method of creating a new biodegradable material consisting of a biodegradable fibril or fibre based binding agent, hereafter known as the Binding Agent, and raw, predominantly Calcium Carbonate based material, hereafter known as the Aggregate, which adds a mechanical strength to the Binding Agent.
In a first aspect, the invention provides a method of forming a new material from two components in the following steps:
a) Collection and granulation of the Aggregate;
b) Preparation of the Binding Suspension;
c) Dispersion of the Aggregate within the Binding Suspension;
d) Moulding of the prepared Aggregate and the Binding Suspension;
e) Formation of a product while eliminating the Flow Agent.
The method is presented as a flowchart in Figure 1.
a,b) Calcium carbonate is abundant in nature and can be found in various waste by-products (for example waste egg shells, waste sea shells, shrimps etc.) and is often discarded without being used to its full potential.
The starting point for this invention was the problem of the eggshell waste from egg processors being sent to landfill due to current laws and regulations. Landfill disposal is expensive and with it a potentially high-in-value by-product is harming the environment. It has been estimated that in the UK, over 12.5 billion eggs have been consumed in 2016 in total. 23% of all these eggs were processed and considering an average weight of 6g for an eggshell, over 17 thousand tonnes of eggshell waste has been sent to landfills in the past year.
With this invention, all this waste can be reduced or even eliminated. Thinking of other predominantly calcium carbonate based by-products and other calcium carbonate based materials, when ground, they could all be used as part of this invention.
c) Natural fibril or fibre based binding agent is a natural material found in nearly all living organisms and is an abundant renewable resource. From the research that has been undertaken, it has been concluded that the Binding Agent requires the Flow Agent to work effectively in forming a new material.
The Binding Agent used in the experiments that led to the invention was Cellulose Microfibrils, however, other fibril or fibre based biodegradable materials may be used with this invention.
The Flow Agent used in the above-mentioned experiments with the Binding Agent was water, however, other flow agents may be used with this invention.
d) Both the Aggregate and the Binding Agent need to be mixed together with the help of the Flow Agent and granules or particles of the Aggregate need to be dispersed within the Binding Suspension to allow consistency of cohesion in the new material.
There is no specific way of dispersion required for this process.
e,f) The prepared Aggregate and the Binding Suspension are moulded into desired shapes and with the elimination of the Flow Agent both the Aggregate and the Binding Agent cohere and a new product is formed.
Material is fully biodegradable and in some occasion even compostable, which allows it to be recycled or even composted, turning into a fertiliser.
Claims (6)
1. A method of creating a new biodegradable material comprising the steps of:
a) Collecting and granulating the Aggregate;
b) Preparing the Binding Suspension;
c) Dispersing the Aggregate within the Binding Suspension;
d) Moulding the prepared Aggregate and the Binding Suspension;
e) Forming a new product by cohesion and elimination of the Flow Agent
2. The method according to claim 1, wherein the Aggregate in step (a) being raw, predominantly Calcium Carbonate based material
3. The method according to claim 1 and 2, wherein the Aggregate in step (a) is ground to a suitable size, allowing cohesion in step (e) to occur, aiding mechanical stiffness to the Binding Agent.
4. The method according to Claim 3, wherein the Binding Agent being a biodegradable fibril or fibre based material allowing partial flexibility to the material.
5. The method according to Claim 1, wherein the Binding Suspension in step (b) consisting of the Flow Agent and the Binding Agent.
6. The method according to Claim 1, wherein cohesion of the material occurs by eliminating the Flow Agent in step (e) while controlling the shape with the mould in step (d).
