Abstracts

English Abstract


ABSTRACT
In North Temperate Zone there are abundant of dead leaves due
to seasonal changes. Usually, these leaves are collected and
disposed of as a waste material. In this invention, the leaves
are turned into a useful and manageable form by pelletizing them.


Claims

Note: Claims are shown in the official language in which they were submitted.


The embodiments of the invention in which an exclusive
property or privilege is claimed are defined as follows:
1. Pellets comprising dead leaves, one or more binding
materials, colouring, preservatives and/or flame-retardants.
2. Pellets as claimed in claim 1, in which the pellets are
laminated with suitable materials to be used for building's
interior wall panels, ceiling tiles, and etc.
3. Pellets as claimed in claim 1, in which pellets are
turned into energy bundles of suitable shapes and sizes to be used
as a solid fuel source.

Description

Note: Descriptions are shown in the official language in which they were submitted.


SPECIFICATION
This invention relates to a transformation of a waste material
into a useful material.
Dead leaves that occur naturally during seasonal changes have
collected and wasted because they can not be utilized conveniently
in their original form as individual leaf although each leaf
possesses physical and caloric properties similar to that of a
piece of paper of a comparable size.
I have found that this disadvantage associated with the leaves
in their original form may be overcome by pelletize them into
desired shapes, sizes and densities, and utilize them as a useful
material. The pelletization may be achieved by mixing the leaves
with suitable chemicals for bonding, colours, preservation and/or
flame-retardation and pressurizing the mixture.
