Here are a few common items that cause confusion:. Shredded Paper: Ever wondered whether shredded paper can be recycled? The answer is yes , though you may encounter some local restrictions regarding the size of the shredded pieces and the way the paper is contained. Check with your local recycling program for specific information.
It is probably in your best interest to remove paper clips, though, so they can be reused. Sticky Notes: If your local recycling program accepts mixed paper, it will most likely accept sticky notes. Paper mills that process mixed paper are able to remove adhesives.
The amount of paper recovered for recycling in averaged pounds for each man, woman and child in the U. It was updated on July 1, with new information and updated links.

How is Paper Recycled? In any case, the production of paper fiber from wood is energy intensive, and produces air emissions and wastewater effluent containing toxic compounds.
Using recycled fiber avoids the most serious impacts of the papermaking process. If high grade paper is kept separate from other grades, it can be used in the production of more high grade paper, and is thus of higher value.
Mixed high and low grade paper can only be used for low-end products. Facilities may find it worthwhile to separate paper into categories including: Office Paper Magazines Newspapers, Telephone Directories Corrugated Boxes Impacts of papermaking At about 36 percent, paper and paperboard products constitute the largest portion of the MSW stream. Americans generated nearly 82 million tons of paper products in the MSW stream in , nearly a three-fold increase from Several toxic chemicals, including toxic sulfur compounds and chlorine, are used and discarded in making paper from wood Compliance Requirements The major compliance issue associated with paper waste involves the Health Insurance Portability and Accountability Act HIPAA.
Alternatives Reduction in use when possible Source reduction is the process of reducing the amount or toxicity of waste generated. One form of source reduction is "lightweighting. Manufacturers of paper food service disposables have been able to source reduce by decreasing the paper stock required to manufacture food service containers and coating the containers with a very thin layer of polyethylene or wax.
The coating enables the container to maintain its strength and food-protection functions. Maximize recycled content of papers you buy Recycling Reduces greenhouse gas emissions that could lead to damaging climate change. Thank you. I was wondering about this as well. If they are too small, would it be possible to stick them inside an envelope to ensure they get recycled?
Clothing tags are still quite a bit larger than shredded paper. Maybe we could make sure our receipts will not be coated with BPA instead of arguing about whether we should recycle them or not. Please start calling all receipt manufacturers and work on changing all of the processors that use BPA to print their recipes.
Receipts are printed not with ink, but are thermally imprinted onto the paper. In the mean time, receipts, like Jule said, should NOT be recycled. Hi, I made a post on my Instagram account asking for advice on how to recycle old birthday and xmas cards that have glitter on them. No one seemed to know! So what should I do? I was thinking of cutting and bining the parts with glitter but some cards have so much! Would love to know what you think. What do you do with paper containing confidential information that you want to dispose of?
Do you shred? Please advise. Thank you so much for the helpful tips! Check with your local recycler. Where we live, it does need to happen.
Thank you for the great post. Do you have any tips for what to use instead of paper cups for a business setting? Any advice would be appreciated. Thank you for this informative post! Never thought to rip the top of pizza box off? Here in UK we can put shredded paper in recycling bin, but packed in a paper bag or envelope depends on the council too. Luckily some still use uncoated paper printed ones, others bakeries, coffee shops oftentimes ask you, if you want a receipt printed at all.
Most decline. Some light is absorbed, but the remainder passes into the air and is reflected and refracted again by new fibres and pigments.
After a number of reflections and refractions, a certain proportion of the light reaches the paper surface again and is then reflected at all possible angles from the surface. We do not perceive all the reflections and refractions the multiple reflections or refractions which take place inside the paper structure, but we perceive that the paper has a matt white surface i.
Some of the incident light exists at the back of the paper as transmitted light, and the remainder has been absorbed by the cellulose and the pigments. Besides reflection, refraction and absorption, there is a fourth effect called diffraction.
In other contexts, diffraction is usually the same thing as light scattering, but within the field of paper technology, diffraction is only one aspect of the light scattering phenomenon.
Diffraction occurs when the light meets particles or pores which are as large as or smaller then the wavelength of the light, i. These small elements oscillate with the light oscillation and thus function as sites for new light sources.
When the particles or pores are smaller than half of the light wavelength the diffraction decreases. It can be said that the light passes around the particle without being affected Pauler The opacity, brightness, colouring and brilliance are important optical properties of papers and paperboards. For example the high value of opacity is need at the printing papers, but opacity of translucent paper must be lower. The paper producer must understand the physical principles of the paper structure and to determine their characteristics composition.
It is possible to characterize nondirect the paper structure. The opacity characterizes the paper ability to hide a text or a figure on the opposite side of the paper sheet. The paper brightness is a paper reflection at a blue light use. The blue light is used because the made fibers have yellowish colour and a human eye senses a blue tone like a white colour. The recycled paper is increasingly used not only for the products of short term consumption newspaper, sanitary paper, packaging materials e.
The study of the recycled papers alterations in the ageing process is therefore important, but the information in literature are missing. The recycling is also another form of the paper ageing. It causes the paper alterations, which results in the degradation of their physical and mechanical properties.
The effect of the paper ageing is the degradation of cellulose, hemicelluloses and lignin macromolecules, the decrease of low molecular fractions, the degree of polymerisation DP decrease, but also the decline of the mechanical and optical properties El Ashmawy et al.
Cellulose as the most abundant natural polymer on the Earth is very important as a renewable organic material. The degradation of cellulosebasedpaper is important especially in archives and museums where ageing in various conditions reduces the mechanical properties and deteriorates optical quality of stored papers, books and other artefacts. The low rate of paper degradation results in the necessity of using accelerating ageing tests.
The ageing tests consistin increasing the observed changes of paper properties, usually by using different temperature, humidity, oxygen content and acidity, respectively.
Ageing tests are used in studies of degradation rate and mechanism. During the first ageing stages—natural or accelerated—there are no significant variations in mechanical properties: degradation evidence is only provided by measuring chemical processes. Oxidation induced by environmental conditions, in fact, causes carbonyl and carboxyl groups formation, with great impact on paper permanence and durability, even if mechanical characteristics are not affected in the short term Piantanida et al.
During the degradation two main reactions prevail — hydrolysis of glycosidic bonds and oxidation of glucopyranose rings. As a result of some oxidation processes keto- and aldehyde groups are formed. At the accelerated paper ageing the decrease of DP is very rapid in the first stages of the ageing, later decelerates.
The similar dependences were obtained at the photo-induced cellulose degradation Malesic et al. An attention is pay to the kinetic of the cellulose degradation in several decades, this process was studied by Kuhn in and the first model of the kinetic of the cellulose chains cleavage was elaborated by Ekenstam in This model is based on the kinetic equation of first-order and it is used to this day in modifications for the watching of the cellulose degradation in different conditions.
Hill et al. Experimental results are often controversial and new kinetic model for explanation of cellulose degradation at various conditions was proposed Calvini et al. The first-order kinetic model developed by these authors suggests that the kinetics of cellulose degradation depends upon the mode of ageing.
An autoretardant path is followed during either acid hydrolysis in aqueous suspensions or oven ageing, while the production of volatile acid compounds trapped during the degradation in sealed environments primes an autocatalytic mechanism. Both these mechanisms are depleted by the consumption of the glycosidic bonds in the amorphous regions of cellulose until the levelling-off DP LODP is reached. The DP decrease is caused by two factors in accordance with equation. There is a first factor higher and quickdecreasing during eight days and a second factor is lower and slow decreasing and dominant aftereight days of the accelerating ageing in the equation.
The number of cleavaged bonds can be welldescribed by equation. The equation of the regression function is in accordance with Calvini et al. The decrease of the rate constant with the time of ageing was obtained also by next authors Emsley et al.
The ageing of the recycled paper causes the decrease of the pulp fiber DP, but the paper remains good properties. The recycling is a necessity of this civilisation. It is increasingly assented the trend of the recycled fibers use from the European and world criterion. The present European papermaking industry is based on the recycling. The presence of the secondary fibres from the waste paper, their quality and amount is various in the time intervals, the seasons and the regional conditions.
It depends on the manufacturing conditions in the paper making industry of the country. At present the recycling is understood in larger sense than the material recycling, which has a big importance from view point of the paper recycling.
Repeatedly used fibres do not fully regenerate their properties, so they cannot be recycled ad anfinitum. It allows to use the alternative possibilities of the paper utilisation in the building industry, at the soil reclamation, it the agriculture, in the power industry.
