The present invention relates to a composition comprising clay and a sample of biological material of human, animal or vegetable origin. Moreover, the invention relates to the use of said composition for manufacturing an emotional or commemorative object, or a reliquary.

The purpose of the composition of the invention is to create an emotional bond between an object comprising said composition and the user who acquires it.

The present invention relates to a porcelain stoneware element for the construction of driveways.

The invention involves a silky, fine-grained matte ceramic tile and its preparation method. A blank material for the ceramic tile consists of the following components: nepheline powder: 10%-15%; high-carbon mud: 10%-15%; low-carbon mud: 15%-22%; medium-high-carbon mud: 10%-15%; recycled waste blank: 5%-10%; feldspar powder: 5%-10%; albite powder for paving: 12%-20%; waste porcelain powder: 5%-10%; desulfurized waste: 0%-7%; waste from edging and polishing: 15%-26%; liquid gel remover: 0.3%-1.0%; liquid reinforcing agent: 0.2%-0.8%. Its preparation method comprises the following steps: preparing raw materials for a blank body and ball milling.fwdarw.spray drying.fwdarw.aging.fwdarw.pressing and molding of the blank body.fwdarw.drying.fwdarw.polishing the blank body.fwdarw.spraying water.fwdarw.applying a glaze.fwdarw.applying a decorative pattern.fwdarw.firing.

The present patent document refers to the products and processes of Ceramic Proppant production from iron ore and/or sterile from its exploitation and/or tailings from its beneficiation, and/or fine and ultra-fine particles from other sources with similar properties, by agglomeration of these materials, and subsequent heat treatment, resulting from the combination of different technologies, previously used for other purposes, capable of obtaining a ceramic material, transforming the materials, including waste and sterile from other processes, into high value products, and reducing the impact of mining activity, with the best use of mineral resources.

In the future, this practice may allow for the reduction of waste and tailings disposal in new dams and piles, as well as the resumption of structures such as piles and old dams.

A ceramic for construction or technical applications, composed of at least one of Municipal Solid Waste Incinerator Bottom Ash (MSWIBA) and other recycled industrial solid waste and different methods of forming such ceramics. Various techniques illustrate how ceramics are formed using at least one of extrusion shaping, dry powder compaction and agglomeration, any of which can be preceded by a pre-treatment process of received feedstock.

The present invention relates to a composition that comprises clay and ashes originating from the cremation of dead persons, animals or vegetables and the purpose whereof is to create an emotional bond between the piece created with said composition and the user who acquires it.

The present invention relates to a process for producing building materials, such as bricks, lightweight aggregates and concrete, which building materials comprise digestate obtained from municipal solid waste (MSW) which has been added one or more enzymes to liquefy the organic fraction of MSW.
