Abstract:

This paper argues that the American newsprint recycling laws passed during the late 1980s and early 1990s not only failed to achieve their stated environmental objectives, but failed so spectacularly that they actually contributed to further environmental harm. These laws, which imposed a recycled content standard on new newsprint production, had three intentions: to decrease landfill space requirements, to preserve forests, and to encourage the recycling of used newsprint. Insofar as the first two intentions are concerned, this paper finds that the American newsprint recycling laws had a negligible effect on both landfill space and forest conservation. But by succeeding in elevating the amount of newsprint recycling far beyond what it would otherwise be, industry compliance with these laws may have actually increased environmental harm. From a Canadian perspective, these laws essentially encouraged Canadian newsprint producers to import American newsprint waste. In addition, by imposing compliance costs on American and Canadian newsprint producers in the range of several billions of dollars, these laws prevented capital from being productively spent on other environmental initiatives. Surveying alternatives to government mandated recycling legislation, this paper ends by concluding that if governments wish to improve environmental outcomes through newsprint recycling, their best option may be to extend the functioning of markets.

Abstract:

Virgin newsprint paper from thermo-mechanical pulp was subjected to a laboratory recycling scheme, which involved mimeograph-printing, re-pulping, de-inking, washing, refining, and handsheetforming, without adding other fibre in between cycles. Fibre dimension, pulp freeness and paper properties were determined after each cycle until the fifth, at which about 20% of the original material remained. The remaining fibre was then mixed with virgin pulp, the original newsprint and unsorted mixed office waste to determine the proportion necessary for acceptable properties. The results indicated remarkable modification in distribution of fibre properties, a decreasing amount of long fibre with corresponding increase of short fibre in the course of recycling and loss of fibre. Refining generally improved the strength properties of paper from recycled fibre. About 20 % to 30 % of either thermo-mechanical pulp or unsorted mixed office waste was found sufficient for blending with recycled fibre to obtain acceptable strength properties.

Abstract:

AbstractThe quantity of paper recycled in the U.S. has more than doubled since 1985. International trade theory predicts that this will lead to reduced imports of paper, and a shift in domestic production toward waste paper intensive outputs (e.g., newsprint) and away from higher grade products such as printing/writing paper. Import demand elasticities with respect to input prices were estimated for newsprint, printing/writing, and all paper utilizing 20 years of monthly data. The empirical results confirm the predictions of theory, and illustrate a channel through which recycling may be more beneficial for U.S. industry than the domestic environment.

Abstract:

This paper derives price-cost margins for the old newspaper (ONP) input market for newsprint manufacture and then examines the effects of two government policies and two variables measuring the market performances of ONP input and newsprint output on the oligopsonist's ONP price-cost margins. In the wastepaper recycling market in particular, the ONP input market has not been successful in using the ONP generated. The outcomes of the study are that various degrees of price distortions existed in the ONP input markets in four regions of the United States during 1972–1995. Demand-side policy had a positive effect and supply-side policy had a negative effect on ONP price–cost margins in all regions.

Abstract:

Utilization of paper wastes as renewable resource of lignocellulosic constituents has the opportunity to promote a cleaner environment and to prepare valuable materials. This paper describes our study on an isolation of low-fiber powder cellulose from two grades of wastes as feedstocks: waste newsprint paper and cardboard wrapper through recycling including a thermal defibration, an alkali treatment with a solution of NaOH with a concentration from 0.03 to 1.00 М, a bleaching with a solution of Н2О2 with a concentration from 0.8 to 2.6 М followed with an acid hydrolysis of the pretreated species with a solution of HNO3 of 1.5 and 3.0 M. An impact of the pretreatment on sizes of fibers was evaluated with a stereoscopic microscopy. The powder celluloses obtained as a result of the acid hydrolysis exhibited the structure of cellulose I revealed with a WAXS method and were of a high-grade purity, according to EDXA. Sorption capacities of the powder celluloses from the waste cardboard and newsprint towards a dye methylene blue were 6.67 mg∙g-1 and 8.75 mg∙g-1 correspondingly.

Abstract:

One of the existing priorities of the European Union is to search for rational waste management and to keep such waste in the economic cycle, while meeting the highest safety requirements. The paper presents the results of environmental tests of composites based on the polyethylene (rPE) and polypropylene (rPP) matrix and reinforced with cellulose fibres (newsprint, NP). Raw materials were obtained by recycling post-consumer waste such as beverage bottles and newsprint. The composites were tested for their potential use as materials in cladding panels and acoustic barriers. Given that normative documents for these products do not define specific environmental requirements, the composites were tested for the release of dangerous substances, such as anions of inorganic compounds, heavy metals, volatile organic compounds (VOCs), and their impact on the environment. A detailed in-depth analysis of the mechanisms of release of substances (diffusion, dissolution, surface leaching and depletion) from the rPP/NP composite into surface water, groundwater and soil was carried out. In turn, emission of VOCs from the rPE (low-density:high-density (LD:HD)—50:50) and rPE (LD:HD—30:70) composites into indoor air was also carried out. Raw materials in the form of granulates and loose cellulose fibres, used to produce the composites, were also tested for their environmental impact.

Abstract:

Wastewater treatment sludge, which is the largest volume residual waste stream generated by the pulp and paper industry, is generally disposed of in a dedicated landfill. Composting the sludge is an alternative method proposed by the Asian Regional Research Program on Environmental Technology-De La Salle University (ARRPET-DLSU) Minor Issue Group. The Philippine Department of Agriculture's (DA) standards for an organic fertilizer's maximum allowable content of heavy metals provided the legislative regulation for the conversion of sludge to compost. The research was designed to characterize the sludge samples from TIPCO, a Philippine paper-recycling mill, and establish whether the sludge contained the heavy metals cadmium, chromium, lead, mercury, nickel, and zinc using atomic absorption spectrophotometer (MS). Sampling was done for four weeks during newsprint and white paper production. Three discharge terminals were established as sampling points. The samples showed that the metal content of the sludge vary from point to point and was highest throughout the manufacture of white paper. Chromium, mercury, and nickel, however, were nondetectable in all the samples, while cadmium was detectable only in very few samples. Lead and zinc were present at all three points and were highest at the de inking sludge. Comparing the results with Part 503 of the United States EPA and the DA's guidelines for organic fertilizers yield significantly lower parameter values. Composting the sludge was, therefore, found to be a feasible option for recycling paper-mill sludge since the metal content were very low compared to local and international standards.

Abstract:

The bottom has fallen out of the market for recycled newspapers, exacerbating the nation's already critical garbage problems. The market's collapse stems from a sudden deluge of old newspapers, the result of new recycling programs by several Eastern states. In response, Korean and other foreign and domestic paper companies have greatly lowered the price they are willing to pay for old papers. The result: Municipalities that just two or three months ago were receiving as much as $25 a ton for their newspapers from brokers now are having to pay these brokers $5 to $25 a ton just to haul the old papers away. . . Worse is yet to come, according to the American Paper Institute, the industry's trade group. It predicts that so much old paper will soon flood the market that some of it may have to be dumped in landfills. . . To be sure, nobody predicts the end of recycling because, especially on the East Coast, landfills are full, and many new incinerator projects are stalled by citizen's groups worried about possible adverse health effects. . . Michael Koplik, president of Percy H. Koplik & Sons, Inc., which buys old newspaper for paper companies, says the current depression in the market could last a year or longer. But he also calls the downturn an opportunity, in that he expects paper companies to commit to building more plants that use recycled paper. Joseph Salomondo, editor of Recycling Times, also foresees new uses for recycled newsprint—in particular, as housing insulation and as animal bedding. . .

Abstract:

In the effort to produce sustainable concrete, considerable attempt has been placed on replacing the main ingredients in concrete mixtures with more sustainable materials with the objective to reduce the carbon footprint. One of the replacement materials is waste paper sludge ash (WPSA), a local industrial by-product generated abundantly by newsprint mills which possesses considerable cementitious properties. Parallel to this, the high amount of construction waste, particularly concrete waste has become a difficult environmental issue to cope with in todays world. For this reason, recycling of concrete waste as a new alternative aggregate is being effectively utilized in concrete production. Thus, this paper reports on a study conducted to evaluate the compressive strength characteristics of the potential of using WPSA as a binder and fine recycled concrete aggregate (FRCA) as a virgin sand replacement in producing foamed concrete. The findings of this study exhibited that the inclusion of WPSA and FRCA for replacement ratios up to 20% and 15% respectively has significantly influenced the strength properties of foamed concrete.

Abstract:

The acid hydrolysis of cellulosic wastes has attracted the attention of many research workers around the world, especially in the last decade. This high temperature and pressure process results in the production of sugars which may be fermented to ethanol. By virtue of their cellulosic content, agricultural, industrial and municipal solid wastes may all be processed by acid hydrolysis with an end result of waste disposal and recycling/recovery of important energy sources. The complete process of the conversion of a cellulosic waste through to the end product and by-product utilization has to give due consideration to likely technologies. Some essential problems that have to be tackled are raw material storage, availability and preparation, the optimum acid hydrolysis and fermentation conditions and product separation methods. This paper is a review of the research that is taking place not only in the field of acid hydrolysis but also in the types of waste used, the concentration of the product sugars, the optimization of the fermentation conditions and the use of low-energy alcohol recovery methods to replace conventional distillation. Most research is at bench scale level with some pilot plants being reported. Also included is the authors' current work using a continuous reactor for the hydrolysis of newsprint.

Abstract:

NOx is unavoidably emitted during combustion in air at high temperature and/or pressure, which, if exceeding recommended levels, has a negative impact on the population. The authors found that when moist, limestone (CaCO3) readily sorbs NO2 to form calcium nitrate, which provides the basis for developing a surface flow filter. The substrate was made from “over-recycled” cellulose fibres such as newsprint, magazines, or packaging fibre, which are too weak to be used in further recycling. The substrate was specially-coated with fine-ground calcium carbonate and micro-nano-fibrillated cellulose, which was used as a binder and essential humectant to avoid formation of a stagnant air layer. Pre-oxidation countered the action of denitrification bacteria colonising the cellulose substrate. The by-product CO2 produced in situ during carbonate to nitrate conversion was adsorbed by perlite, which is an inert high surface-area additive. After use, the nitrate-rich CaCO3-cellulose-based filter was proposed to be mulched into a run-off resistant soil fertiliser and micronutrient suitable, e.g., for renewable forestry within the circular economy. Belgrade, Serbia, which is a highly polluted city, was used as a laboratory test bed, and NO2 was successfully removed from an inlet of city air. A construct of street-side self-draughting or municipal/commercial transport vehicle-exterior motion-draught filter boxes is discussed.

Full text

Abstract:

Pigmented nonimpact (inkjet) printing is a concern in conventional flotation deinking, due to the problems associated with the hydrophilic, submicron-size pigment particles of the ink. Preliminary experiments were conducted to evaluate the efficiency of a conventional flotation deinking process in detaching those inkjet particles from the fiber surfaces and network. A Denver D-12 laboratory flotation cell was used to test 100% old newsprint paper (ONP) with the ISO brightness target set to 58, which makes a paper recyclable. The inkjet-printed ONP was floated to 47 ISO brightness by the INGEDE Method 11. It was enhanced to 50 ISO brightness using flotation, with the addition of nonionic surfactant for better repulping. In addition, a patented electric field technology was used for further improving the floated ISO brightness to 52.5—yet still short of the 58 target for recycling. This improvement was reached with small air bubble sizes, which are more likely to collide and interact with ink particles, causing additional ink to be brought up to the surface of the water pool. The increasing problem of deinkability from digital nonimpact inkjet printing means that additional technical efforts are needed to overcome the crossroad between environmental concerns and technological progress. Papermills, inkjet suppliers, printer manufacturers, and academic and industrial deinkers should take collective action to meet the challenges to future success.

Abstract:

Paper as a material needs a lot of input energy. Many measures have been suggested to recycle paper, but still a huge amount of it ends in landfills. Hereby, one possibility for recycling paper - making paper plaster and putting it into service in indoor environment - is introduced. The study focuses on the moisture buffering properties of paper plaster. Two questions are under consideration in this article. Firstly, how paper type and production method influence the properties (dry density, drying shrinkage) of paper plaster, and secondly, what the material moisture buffering properties of paper plaster are. The plasters for testing were made from four types of paper (printer paper, glossy paper, newsprint and book paper). The production methods used were rumpling, grinding with a shredder or special crusher (prepared for the study) and soaking the paper after that. The dry density of groups varied from approx. 240 kg/m3 to 400 kg/m3. The shrinkage properties were from 3% to 10% in diameter. To evaluate the moisture buffering ability of paper plaster, the methodology introduced in the Nordtest protocol was used. Paper plaster is an outstanding water vapour buffering material [MBV=2.23-3.91 g/(m2·%RH)] belonging to the moisture buffering class "excellent" defined by Rode [15]. From the production methods rumpling gave the best value while printer paper showed the best values from the chosen materials. The tests with glossy paper resulted in modest values. To conclude, all the paper materials and preparation methods introduced in this study can be used to make paper plaster

Abstract:

Even though it is supported by the Smart City label, as the capital city of West Java Province, Bandung is still having trouble handling waste. The plan to use incinerator technology at the Sarimukti landfill has never been built because it is considered a threat to the environment and public health. Furthermore, biodigester technology from Japan was initiated, but it did not materialize. As a result, waste becomes an unresolved problem. Therefore, according to Law no. 18 of 2008 concerning Waste Management, the paradigm of waste management must be changed from collect-transport-dispose to reduction at source and recycling through the 3R principle (reduce, reuse, recycle). “Pasigaran Handmade and Crafts” was established on July 16, 2019, having its address at Pasigaran Village, Citeureup Village, Dayeuhkolot District, Bandung Regency, West Java Province. This business was founded on the anxiety of companions because more and more poor people need government assistance but cannot be covered by the government budget, in addition to the abundance of paper waste that is no longer used so that the idea of turning newsprint into a variety of recycled products such as wall clocks, bags was born. , tea sets and various containers. The essence of planning is how to determine various programs and activities aimed at gradually achieving long-term goals. Therefore, the preparation of programs and activities must be based on organizational goals, both short term (0-2 years) and long term (2-5 years). Performance measures are carried out by setting indicators of success, both short term and long term

Abstract:

De-inked paper sludge from newsprint recycling was evaluated as an alternative amendment in bedding plant production. `Sweet Dreams' geranium (Pelargonium × hortorum) and `Crystal White' zinnia (Zinnia angustifolia) were grown in square 10-cm pots in one of five media. Media contained 0%, 20%, 40%, 60%, or 80% de-inked paper sludge by volume. All mixes contained 10% perlite, and peatmoss was used to bring the volume to 100%. Initial chemical and physical characteristics of the media were determined. Plants were grown in a greenhouse for 8 weeks, and then plant height, shoot dry weight, and average plant width were determined. Media containing 20% or less paper sludge had an average pH of 4.4, whereas those containing more sludge had an average pH of 7.0. Cation exchange capacity of the media decreased significantly as the volume of sludge increased. Media containing 60% or more paper sludge were better aerated, but held less water than those made with 40% or less de-inked sludge. Geraniums grown in 20% or less paper sludge were at least 18% taller than those grown in medium containing 40% or more de-inked sludge, but average dry weights and plant widths of these plants were unaffected by the media. Zinnia plants grown in 20% or less paper sludge produced four times more shoot dry weight and were at least 34% taller and 20% wider than those grown in 40% or more sludge. Overall, zinnias grown in 40% or more sludge were unacceptable for commercial sale. A volume of 20% de-inked paper sludge could safely be included in potting media used for production of `Sweet Dreams' geranium and `Crystal White' zinnia.

Abstract:

The volume and structure of solid domestic waste in Ternopil region are analyzed. Our research in the Baikivtsi Utc proves that community residents dump less organic waste in containers (about 20%, which is twice less than in the regional center) because they can compost food waste using it as fertilizer for personal use plots (gardens). The volumes of organic waste fluctuate significantly throughout the year: the largest amount of them ends up in containers from May to September. The community residents throw out the least of organic waste in winter. One of the reasons is that there is a gradual replacement of last year's harvest with a new one. The habitants of the Baikivtsi Utc throw more paper away during the warmer months. The following types of paper prevail: offset - 33%, newsprint - 29%, coated - 4%, cardboard - 12%, designer - 5%, packaging - 16%, self-adhesive - 1%. In winter, most of the paper is burned to heat buildings. Among the scrap are mostly cans and metal lids (from bottles and cans). Ferrous metal almost never gets into containers due to the fact that it is profitable to sort it out and there are no problems to hand over scrap metal, since scrap collectors often come to the villages and offer quite decent price for it (therefore, there is no need to waste time transporting the metal). The plastic waste of the community includes plastic bottles from water, oil, household chemicals, canisters, plastic bags and ets. Among the various types of plastic: Polyethylene terephthalate or PET - 17%; high-density polyethylene (HDPE) - 29%; polyvinyl chloride or PVC - 4%; low density polyethylene (LDPE) - 34%; polypropylene, PP or PE - 8%; polystyrene, PS - 6% and other - 2%. The research showed that the following types of glass prevail in the structure of the cullet of the Baikivtsi community: window glass - 8%, technical glass - 3%, Plexiglas - 5%, triplex - 3%, glass from chemicals - 1%, ceramics - 10%, bottles - 70 % The survey showed that only 3% of the community's residents completely sort garbage, about 80% of them sort it partially, and almost 20% do not sort waste at all (and 12% of them plan to do it in the future). The reasons for the low level of waste sorting are not surprising, since, in addition to the low level of environmental awareness of the residents, there no proper conditions for sorting solid waste. The environmental advantages of sorting and recycling solid domestic waste were evaluated. In particular, the volumes of biogas that can be formed from the annual volumes of solid waste accumulation in the Baikivtsi united territorial community of Ternopil region, as well as the assessment of the environmental efficiency of recycling waste paper, plastic, glass were calculated. The cost of the Baikivtsi Utc solid waste as a secondary material resource will amount to UAH 2,051,943 per year, which can be a significant profit for the community. Key words: solid domestic waste, united territorial community, sorting, utilization, recycling ecological culture.

Abstract:

AbstractDry-process hardboard represents a favorable option for recycling old newspaper fibers. However, dry-process boards tend to be less dimensionally stable than boards processed by other methods. Our objective was to determine the effects of various wood fiber (WF) to old newspaper (ONP) ratios (100:0, 50:50, and 0:100 WF/ONP) on the mechanical strength and water resistance of dry-process hardboards made from these fibers. Untreated and acetylated hardboards were made with 3 or 7 percent resin and 0.5 percent wax. Boards were tested for static bending and tensile strength properties and water resistance. As expected, increasing the resin level from 3 to 7 percent generally improved all measured properties. Acetylation substantially improved the water resistance of all boards; increasing the amount of ONP caused a corresponding deterioration in both mechanical properties and water resistance.

Abstract:

In recent yr. due to reduced ligneous resources, increased demand for paper products, increased environmental concerns that are made from virgin papers production, and high volume of waste papers, the need for recycling of papers is felt more than ever. One of the important steps in the process of recycling paper is the deinking of waste papers. The purpose of this study is the deinking of the old magazine papers in order to produce newsprint. In the review, old magazine papers were deinked by Flotation method using: Sodium hydroxide (1%), Sodium silicate (2%), Hydrogen peroxide (1%), and DTPA (1%). Then they were bleached with an amount of Hydrogen peroxide (1/5%). 60 grams of paper was made under standard conditions for testing. Then the brightness of handmade papers was measured in three replicates. The result showed that the brightness of non-deinked papers was about 40%, after deinking, it was about 50%, and after bleaching, it was increased to about 60%. Results indicate that the use of Hydrogen peroxide and its derivatives in bleaching of waste papers are resulted in increasing brightness in several percent. By combining pulp prepared from recycled magazine paper with CMP pulp prepared from a broadleaf species, the results showed that the addition of deinked OMG significantly reduced the brightness of the control sample. Also, adding deinked magazine paper in any proportion to the mixture of imported CMP pulp and long fiber pulp (by increasing the opacity) improves the quality of the printed paper obtained. This recycled paper can be used in production papers that are used temporary and do not need high resistance (such as newsprints).

Abstract:

AbstractThe reduced interfiber bonding capability and reduced conformability of recycled fibers compared to virgin wood pulp fibers is caused by the drying phase of the first papermaking cycle. Changes in the fiber result in stiffness. This effect is more pronounced in chemical pulps than in high lignin content mechanical pulps. This chapter describes methods for restoring some or all the interfiber bonding. In an attempt to develop a “dry” newspaper recycling process, the water-intensive repulping and paper-forming steps were replaced with dry-fiberizing, air-forming, gas-phase ozone and ammonia treatments, and pressdrying. The tensile strength of the dry-recycled paper approached that of the original newsprint.

Abstract:

Meeting the demand of paper and paper product requirement and at the same time decreasing the availability of fibrous raw materials, keeping an eye on cost effectiveness is challenging. Thus, recycling of paper is an alternative. Corrugated box, old newspapers and office waste papers are the sources of raw materials for paper and paper product industries. Deinking is an important step for recycling of old waste writing, printing and newsprint papers. The efficiency of ink separation in the process of waste paper recycling depends on the ink properties, kind of the additives, surfactants used, age of waste papers, the printing techniques and printing conditions. In general, deinking process consumes a large amount of chemicals which makes this method expensive, pollution intensive and even quality is compromised. In this study the effectiveness of surfactants like benzene dodecyl sulphonate, lauryl benzene sulphonate and sodium carbonate for cost effective deinking process by optimizing the chemical doses has been studied. The physical strength and optical properties of the paper after deinking was also explored. The surfactant better for both physical strength properties and optical properties of paper is identified to be the sodium dodecyl benzene sulfonate.
