Description
DESCRIPTION
Method for manufacturing a disposable product in biodegradable material based on citrus fruit pulp and related disposable product.
The present invention relates to a method for manufacturing a disposable product in biodegradable material based on citrus fruit pulp.
Moreover, the present invention relates to a disposable product in biodegradable material based on citrus fruit pulp.
In particular, the present invention relates to a disposable product in biodegradable material based on citrus fruit pulp, of the type usable as disposable tableware, such as for example disposable plates, glasses or cutlery.
In recent years, the use of biodegradable materials for commonly used products has been the subject of growing interest. Numerous recent studies aim at the development of new plant-based materials to obtain eco-compatible products. This issue is particularly felt in the context of disposable products that are currently produced in plastic material and constitute an important volume of urban solid waste and a non-negligible environmental problem.
An example of known biodegradable material products is described in the Chinese patent application CN109077567 (A) which describes ecological natural disposable tableware made with leaves of woody plants and a method of their preparation. The dishes obtained from the leaves are made by crushing, gluing, and hot pressing. The raw materials mentioned in the document are lychee leaves, banana leaves, elm leaves, grape leaves, orange leaves, mulberry leaves, lotus leaves, Japanese banana leaves, tea leaves, myrtle leaves, glutinous rice, millet and the like.
There are also disposable table wares made from cellulose and corn derivatives.
Although advantageous in some respects, currently known disposable products in biodegradable material suffer of the problem of having poor heat resistance, insufficient mechanical strength for application as dishes for serving and consuming food.
Furthermore, currently known disposable products in biodegradable material do not have as raw material vegetable products that are abundant in Italy and which in particular are waste.
The citrus fruit pulp, define what remains of the citrus fruits after squeezing, and it is the wet residue that remains at the end of the industrial production of
citrus juice and which represents about 50% of the weight of the processed fruit. According to some studies, the pulp produced in Italy amounts to about 1 million tons per year.
The purpose of the present invention is to provide a method for manufacturing a disposable product in biodegradable material based on citrus fruit pulp and a related disposable product that allows the use of waste plant material with the reduction of production costs. Furthermore, the object of the present invention is to provide a method for manufacturing a disposable product in biodegradable material based on citrus fruit pulp which has mechanical and thermal resistance, which does not release toxic substances in contact with food and which is easily biodegradable, and therefore having characteristics such as to overcome the limits that still affect the current products in biodegradable material and production methods with reference to the known art.
According to the present invention, a method for manufacturing a disposable product in biodegradable material based on citrus fruit pulp is provided, as defined in claim 1.
According to the present invention, also a disposable product in biodegradable material based on citrus fruit pulp is provided, as defined in claim 8.
