Many people are still unaware of the benefits of recycling and the importance of properly disposing of waste. Educating consumers about the value of recycling and providing convenient recycling options can help increase participation and drive demand for recycled products. In conclusion, the market for waste recycling composition is experiencing significant growth due to increased environmental awareness, government support, technological advancements, and economic incentives. As the world continues to prioritize sustainability and waste reduction, the demand for recycled products and materials will continue to rise. However, addressing infrastructure limitations and improving consumer education will be crucial in unlocking the full potential of the market.

The Eastman Chemical Co invention works as follows

A recycled cellulose fiber composition that comprises recycled cellulosic fibres and cellulose ester staple fibers is provided. The co-refined recycled cellulose fibres and cellulose ester staple fibers in the recycled cellulose can be added to an hydropulper, and then fed through a refiner for wet laid products.

Background for Waste recycle composition

Many of the wet-laid webs/sheets are used in food packaging and containers, as well as paperboard. While recycling has been a great success, some products do not find their way to the waste/recycle stream. Both manufacturers and consumers are becoming more aware of the impact that products have on the environment. “There is a continuing need to develop wet-laid products that are made from sustainable materials, and also exhibit environmental non-persistence. The product must satisfy or improve upon one or more of the properties required for application.

The recycle mill market is booming on an industrial scale, thanks to the success of waste/recycling. It uses many of the same processes as a wet-laid facility. Hydropulping, screening and cleaning are common elements. Depositing pulp on a moving wire is also common. Draining and drying are other processes. The recycling mills also have a process step called flotation and deinking. The waste/recyclemills supply bales to wet laid facilities, and then the waste/recyclepulp is added to the hydropulper, which is eventually fed to the refiner or to the blend tank below the refiner.

It would also be desirable to have a synthetic fibre that could be recycled and fed back through a refiner. It is impossible to feed polyolefins or polyesters through a refiner without them aggregating and compromising its operation. Even if these synthetic fibers were added to a furnish that was downstream of a refining operation, the wet-laid products produced by this process are not suitable for recycling because recycled pulp is added into a hydropulper which feeds a refinedr.

It would be desirable to produce wet-laid products using a synthetic fibre suitable for recycling and to develop a composition that contains recycled cellulose fibers, along with synthetic fibers, which can be added to an hydropulper feeding to a refiner.

A composition is provided now, comprising or resulting from:

There is provided also a method for making a composition of waste and recycling comprising:

There is provided a composition containing cellulose fibres and synthetic fibers comprising staple fibers of cellulose esters, wherein said fibers are characterized by a denier (DPF), a length cut of less that 6 mm, non-round, and/or crimped. (used throughout the description as ‘Composition’). Compositions can be used in any of the following: in any or all zones or steps in a process, or in one or more vessels, pipes, or machines, during a stock preparation or wet-laid machine process. They can also be used in wet-laid articles. The compositions can be used as feeds for, inside, or effluents of a hydropulper or any other blending vessel or refiner. They can also be found in the stuff box, headbox, wire, dryers, size press, calendars, sheets on rolls or in any step between. Wet laid articles may contain the compositions, or be obtained by them. They can also be formed with the compositions.

The Compositions contain cellulose fibres and cellulose est fibers, at least a portion which are cellulose staple fibers

Cellulose fibers” are those fibers that are not further chemically derivatized using functional groups. Cellulose fibers are made from virgin material or can be recycled.

The CE staple fibers are synthetic fibers that are derivatives from cellulose obtained through a synthetic process. However, as used herein exclude the regeneratedcelluloses or other derivates cellulose-based such as rayon, viscose, and lyocell cellsulosic fibers.

A ?100% Cellulose Comparative composition? A composition in which 100% of the fiber component is cellulose fibers. It is also the same as a reference composition, including consistency, type of cellulose fiber, formulation ingredients and quantities as well as stock preparation conditions and conditions and refining conditions. If the reference is to either a sheet of wet-laid product, the 100% Cellulose Comparative Composition will also be a sheet- or wet-laid product. Alternatively, if the reference refers to a composition that contains both virgin and waste/recycle fibers, the 100% Cellulose Comparative Composition will also contain the same amount of virgin cellulose fibers to waste/recycle fibers.

A ?cellulose fiber? “A?cellulose fiber” can be made from virgin or recycled fibers and can be fibrillated, non-fibrillated, or both.

?Co-refining? “?Co-refining? Co-refined means that at most one cellulose fiber and one CE staple fiber have been refined together. Cellulose fibers and CE staple fibres in a feed stream to refiners are considered co-refined. A co-refined CE fiber refers to a cellulose fibre that has been refined in the presence a CE staple fibr. A co-refined CE fiber signifies that a CE staple fibre has been co-refined with a cellulosefiber.

The ?consistency? “The consistency” is a measurement of the solids content in a liquid stream. It can be measured by drying a representative of the liquid stream and then dividing the weight from the oven dried solids to that of the representative sample.

A ?machine direction? “A?machine direction? The direction in which the web moves on a machine that is wet laid. The?cross direction? The?cross direction? The direction that crosses or is perpendicular with the MD of the sheet or web.

A ?non-woven web? A web made of fibers without the use of knitting or weaving operations.

A ?Post-Addition? “A?Post-Addition? This is a mixture of fibrillated or refinedcellulose fibers and CE staple fibres. The CE staple fibers are only combined with the other cellulose materials after the cellulose has been refined. If the feed to refiners does not contain CE staple fibres, the CE staple fibers will be deemed not to have co-refined. The Post Addition Composition can be used as a comparison. However, the CE staple fibers do not occur during refinement and are only combined with cellulose fibres after the cellulose has been refined. The Post Addition Composition’s cellulose fibers are refined in the same conditions as the reference Composition. In other words, the consistency of cellulose fiber furnish that is fed to the refiner will be the same consistency as the reference Composition. After the cellulose fibres have been refined, the CE staple fibers are added into the refined cellulose furnish. The consistency of the blend will be adjusted to match the consistency of reference Composition. Post-Addition CE staple fibres are CE staple fibrs that have been added to cellulose after the cellulose has been refined.

A ?thick stock? A stock with a minimum solids content (or stock consistency), of 2.0 wt. %.

A ?thin stock? A stock with a solids content (or stock consistency), less than 2.0 wt. %.

Virgin” is a term that refers to stock or fibers. “Virgin” refers to stock or fibers that are not being used for their intended use. However, the fibers must not have been inked or de-inked when they are contained in a web or other article.

A ?wet laid non-woven product? A product weighing at least 50 wt. Fibers with a L/D greater than 300 have a minimum of 5%.
