    Recycling Center 801 Diamond Valley Drive Open: Daily to the public during daylight hours This guide will help you properly prepare your recyclable materials for drop-off at the Town of Windsor Recycle Center. This is a drop-off facility. It does not have a buy-back option and is for use by residents and small businesses. Following this information will help maintain the facility and the recycling program for the benefit of the community. IMPORTANT… • Do not leave your recyclables in plastic bags. Plastic bags are NOT recyclable! • The plastic item must be a BOTTLE or JAR. with a #1 or #2 on the bottom. • 99 percent of these will have a screw-on plastic lid (which isn’t recyclable). • Plastic containers with a #3 - #7 on the bottom are NOT acceptable. • Tubs, buckets, deli plates, microwave/fast food trays, wrappers, Styrofoam, toys, patio furniture, etc. are NOT acceptable. • Plastic bottles larger than 2.5 gallons are NOT acceptable. • Syringes and other medical supplies are NOT acceptable. Cardboard and Brown Paper Bags Corrugated cardboard is easy to recognize. It is made of paper and has an arched layer called “fluting” between smooth sheets called “liners”. The drop-off site has two 40-yard hydraulic compactor units for collecting corrugated cardboard and brown paper bags. The compaction system is self-activated by depositing the prepared materials into a six-inch tall slot. Flatten boxes. Cut or tear large boxes into sections no larger than 4 feet by 4 feet to prevent jamming the machine. No wet, waxed-coated or food-contaminated boxes.

  • Basics of Kraft Pulping
    Lignin Wood is composed of many chemical components, primarily extractives, carbohydrates, and lignin, which are distributed nonuniformly as the result of anatomical structure. Lignin is derived from the Latin term lignum, which means wood.1 Anselme Payen (1838) was the first to recognize the composite nature of wood and referred to a carbon- rich substance as the “encrusting material” which embedded cellulose in the wood. Schulze (1865) later defined this encrusting material as lignin. Lignin has been described as a random, three-dimensional network polymer comprised of variously linked phenylpropane units.2 Lignin is the second most abundant biological material on the planet, exceeded only by cellulose and hemicellulose, and comprises 15-25% of the dry weight of woody plants. This macromolecule plays a vital role in providing mechanical support to bind plant fibers together. Lignin also decreases the permeation of water through the cell walls of the xylem, thereby playing an intricate role in the transport of water and nutrients. Finally, lignin plays an important function in a plant’s natural defense against degradation by impeding penetration of destructive enzymes through the cell wall. Although lignin is necessary to trees, it is undesirable in most chemical papermaking fibers and is removed by pulping and bleaching processes. 1.1.1 Biosynthesis Plant lignins can be broadly divided into three classes: softwood (gymnosperm), hardwood (angiosperm) and grass or annual plant (graminaceous) lignin.3 Three different phenylpropane units, or monolignols, are responsible for lignin biosynthesis.4 Guaiacyl lignin is composed principally of coniferyl alcohol units, while guaiacyl-syringyl lignin contains monomeric units from coniferyl and sinapyl alcohol.

Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I.

  • VNP Guideline LCA Data for Paper and Board in the Netherlands
    VNP Guidelines - LCA data for paper and board products It is of high importance that the data which isused from generic LCA databases (e.g. ecoinvent) are recent as well as representative for the kind of material used. Paper and board are complex materials that appear in different types suitable for the various applications. This document is set-up to assist LCA experts in finding the right data belonging to the type of paper and board studied. General advices: It is not advisable to use the data from European Life Cycle Database (ELCD) as these data are incomplete and also only ‘cradle to grave’: these are aggregated data hence difficult to identify where impacts come from and thus hardly usable for comparisons or to change for specific situations. Of all other generic databases ecoinvent is the most complete and current database. Other public datasets (e.g. GaBi, Base Impacts and ProBas) are less current and less easy to interpret from a user point of view. For LCA assessments on paper and board produced in the Netherlands it is essential to replace the input of the European average enery mix with input the Dutch energy mix. (NB this is not possible with ELCD as these allow no changes at all). Packaging paper Paper for corrugated board - Papier voor golfkarton Description Corrugated board (in Dutch: golfkarton) is the most commonly used transport packaging. Corrugated board consists of one or more layers of corrugated paper, in combination with one or more layers flat paper. The corrugated paper is called fluting or medium. The flat papers are called liners.

  • General Rules for the Sandy Pines Cardboard Boat Race
    GENERAL RULES FOR THE SANDY PINES CARDBOARD BOAT RACE Build Rules The entire boat must be built out of corrugated or standard cardboard, this cardboard may be as thick or have as many layers as you want. You may not use Paper-mâché to ‘cover’ the hull although it may be used to join cardboard panels or strengthen joints The following materials are also permitted in the construction: Brown wrapping paper, Newspaper, Tissue paper, Cardboard tubes Duct tape, masking tape, gaffer tape and packing tape along with adhesives such as PVA Glue, “liquid nails” or silicone may be used to connect cardboard-to-cardboard or reinforce seams, stress points & joints. Tapes may not be used to waterproof hulls and may not be 'Wrapped' around the hull The following paint types are permitted to help water-seal the hull joints & edges: Rubber ('Caucho'), Standard interior/exterior emulsion paint, one-part polyurethane varnish, Water- based sealant Applied paint, glue & silicone must be dry for at least 24 hours prior to launching, boats that have wet paint or other materials may be disqualified Oars & Paddles must be ‘Homemade’ and are under the same build-restrictions as hulls. Although wooden broom-handles may be used for shafts or handles, the blades themselves must be made from cardboard, however edges can be taped & siliconed if required, but not 'wrapped' in tape or film. Tie- wraps may be used to join the blades to the handles & the same paint rules apply as with boat construction Decorations and props that are not part of the boat's hull or structure can be made of anything as long as they do not add to the strength, integrity or buoyancy of the boat or are going to be removed from the hull prior to entering the water.

    polymers Review A Review of Wood Biomass-Based Fatty Acids and Rosin Acids Use in Polymeric Materials Laima Vevere *, Anda Fridrihsone , Mikelis Kirpluks and Ugis Cabulis Polymer Department, Latvian State Institute of Wood Chemistry, 27 Dzerbenes Str., LV-1006 Riga, Latvia; [email protected] (A.F.); [email protected] (M.K.); [email protected] (U.C.) * Correspondence: [email protected]; Tel.: +371-28869638 Received: 26 October 2020; Accepted: 14 November 2020; Published: 16 November 2020 Abstract: In recent decades, vegetable oils as a potential replacement for petrochemical materials have been extensively studied. Tall oil (crude tall oil, distilled tall oil, tall oil fatty acids, and rosin acids) is a good source to be turned into polymeric materials. Unlike vegetable oils, tall oil is considered as lignocellulosic plant biomass waste and is considered to be the second-generation raw material, thus it is not competing with the food and feed chain. The main purpose of this review article is to identify in what kind of polymeric materials wood biomass-based fatty acids and rosin acids have been applied and their impact on the properties. Keywords: crude tall oil; tall oil; fatty acids; rosin acids; polymer materials 1. Introduction The success of plastics as a commodity has been significant and polymer materials are a part of everyday life. The advantages of polymers over other materials can be attributed to their adjustable properties, low cost and ease of processing. Worldwide, the manufacturing of polymers grows every year, reaching almost 360 million tonnes in 2018 [1]. In the light of environmental challenges of the 21st century, the development of novel low-cost and scalable monomers from renewable resources is essential.

  • Tall Oil Production and Processing
    TALL OIL PRODUCTION AND PROCESSING Tall oil is a mixture of mainly acidic compounds found, like turpentine, in pine trees and obtained as a by-product of the pulp and paper industry. It is used as a resin in many different industries, including mining, paper manufacture, paint manufacture and synthetic rubber manufacture. It is extracted at the pulp and paper mill, and undergoes the first two processing steps there. Step 1 - Extraction of tall oil soap The "black liquor" from the paper making process is concentrated and left to settle. The top layer is known as "tall oil soap", and is skimmed off. The rest is recycled for further use in paper making. Step2 - Production of crude tall oil The tall oil soap is reacted with acid to form crude tall oil. The following reaction occurs: + + R—COONa + H3O → R—COOH + H2O + Na The acids formed from this reaction, along with small quantities of other compounds of similar volatility, make up the crude tall oil. All crude tall oil produced in New Zealand is then sent to a plant in Mt. Maunganui to complete processing. Step 3 - Crude tall oil distillation The oil is distilled into five components with different boiling points: heads (which boils first), then fatty acids, distilled tall oil (a mixture of fatty and resin acids), resin acids (collectively known as rosin) and pitch (the residue). All of these can be used in various industries as is, but some of the rosin is also further processed on site. Step 4 - Production of rosin paper size "Paper size" is the substance that stops all paper from behaving like blotting paper.

Th e possibilities of utilizing waste-paper were examined in the production of MDF. Two kinds of waste-paper (cardboard waste and mixed waste-paper) in two disintegration sizes each were used. Th e composition and length of fi bres and content of the Klasson lignin were examined. Th e following properties were obtained in the boards: bending strength, internal bond, modulus of elasticity and thickness swelling. It is apparent that paper fi bres can be added to wood fi bers in the production of MDF to a maximum of 30%. KEY WORDS: cardboard waste, mixed-waste paper, MDF, disintegration size of waste paper INTRODUCTION Th e limited supply of wood from the forest has initiated research in other materials for production of wood- panel boards. Investigations of the utilization of fi brous agricultural waste material and of high-molecular polymer are well-known and partially practised in industry. Waste paper is a recycled material which is not on the whole used in the production of paper. Th e production and consumption of paper increase every year, this is why waste paper resources will also increase. Th is is the reason why waste paper can be used in other branches of industry.
