UAMN Virtual Early Explorers: Solar System Stars in a Sensory Bottle Relax and imagine the solar system in a vast universe! Materials: Sturdy transparent plastic bottle or jar, glitter, sequins (star-shaped or round), heavy tape or glue. Liquid to fill bottle: • water and food coloring/ tempera paint (water- based) OR • mineral oil and candy decorating dye (oil-based) Instructions: Step 1: Clean your bottle or jar thoroughly to avoid growing mold. Step 2: Add glitter and sequins. Suggested quantity: 2-3 teaspoons for a 16-ounce bottle. Adjust to your preference. Step 3: Fill with your choice of liquid: water or mineral oil. In mineral oil (or baby oil), glitter will stay suspended longer than in water. Step 4: Dye your liquid with a blue color. If you used water, add a few drops of food coloring, liquid watercolor, or tempera paint. If you used mineral oil, use an oil-based dye, such as candy decorating colors, as water-based colors will not work in oil. Enjoy your sensory jar! Talk about our Solar System’s place in our galaxy and in the universe! UAMN Virtual Early Explorers: Solar System At Home in The Milky Way Discover the incredible vastness of our galaxy and beyond! Our Solar System has one star, the Sun. The Solar System and Sun are part of a galaxy: a huge collection of stars, gas, and dust. Our galaxy is called the Milky Way. Scientists estimate that there are between 100 and 400 billion stars just in the Milky Way! The universe contains billions of galaxies like this, each one full of stars. Arches Cluster, the densest known star cluster in the Milky Way. Image: ESA/Hubble. Imagine one of the tiny pieces of glitter in your sensory bottle is the sun, and the much smaller planets are orbiting around it. We cannot see planets easily as only stars produce enough light.

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.

Shrink Sleeve Labels on PET Containers APR Resource Document
Document Number RES-LBL-2 Publication or Revision Date: 1/4/2021 Shrink Sleeve Labels on PET Containers APR Resource Document Introduction This Resource Document presents APR Guidance for characteristics of shrink sleeve labels for PET packaging that will have the most benefit for today’s PET container recycling processes, and that will have the most positive environmental impact in support of the plastics circular economy. Shrink sleeve labels have been developed that allow the label film and inks to have negligible impact on the quality or productivity of PET recycling. Such shrink sleeve labels are in commercial use today, but not yet used widely or routinely. The quality of recycled PET can be improved—to the benefit of all recycling and sustainability stakeholders—when recycling compatible labels become the standard for the PET packaging industry. The resources described herein can be helpful to each segment of the package supply chain: • Consumer brands can learn what comprises a recycling compatible shrink sleeve label and inform their label suppliers that they expect such technologies be offered to them; • Label suppliers can assure brands that PET packages using their products meet recyclability guidance by performing APR Test Methods to demonstrate this; • Converters and manufacturers who want to lead the industry in sustainability can use APR shrink sleeve label design guidance to develop and commercialize innovations that will benefit the entire packaging industry. This document is written to complement the APR Design® Guide for Plastics Recyclability by consolidating key shrink label guidance: https://plasticsrecycling.org/apr-design-guide/apr-design-guide-home The APR offers programs, such as Critical Guidance Recognition, that distinguish innovations that are demonstrated to be compatible with recycling: https://plasticsrecycling.org/recognition/programs This document contains four sections: 1.

Packaging Influences on Olive Oil Quality: a Review of the Literature
Report Packaging inﬂuences on olive oil quality: A review of the literature Selina Wang, PhD, Xueqi Li, Rayza Rodrigues and Dan Flynn August 2014 Copyright © 2014 UC Regents, Davis campus. All rights reserved. Photo: iStockphoto/danr13 Packaging influences on Olive Oil Quality – UC Davis Olive Center, August 2014 Packaging Influences on Olive Oil Quality: A Review of the Literature Extra virgin olive oil is a fresh juice extracted from olive fruits. As with other fruit juices, the freshness and flavor quality of olive oil diminish with time, and the rate of deterioration is influenced by packaging type. To maximize shelf stability, the ideal packaging material would prevent light and air penetration, and the oils would be stored in the dark at 16 – 18 °C (61 – 64 °F). Table 1 indicates how chemical components in olive oil influence the shelf life of the oil. Table 1. How chemical components in the oil can influence shelf life Chemical component Effect on the shelf life Fatty acid profile High level of polyunsaturated fats such as linoleic acid and linolenic acid shortens shelf life; high level of saturated fats such as stearic acid and palmitic acid helps to prolong shelf life. Free fatty acidity Free fatty acids promote oxidation and shorten shelf life. Peroxide value High level of peroxide value shortens shelf life. Trace metals Trace metals promote oxidation and shorten shelf life. Oxygen Oxygen promotes oxidation and shortens shelf life. Moisture Moisture promotes oxidation and shortens shelf life. Phenolic content Phenolics are antioxidants and help to prolong shelf life. While a high quality olive oil under ideal storage conditions can be stored for months, even years, without becoming rancid, oxidation ultimately will lead to rancid flavors and aromas.

DID YOU KNOW? PET (Polyethylene Terephthalate) Is Actually Polyester. When PET Is Used for Bottles, Containers and Other
355 Lexington Ave., Suite 1500 ▪ New York, NY 10017 ▪ www.PETresin.org DID YOU KNOW? Little-Known Facts about PET Plastic . PET (polyethylene terephthalate) is actually polyester. When PET is used for bottles, containers and other applications, it is called PET or PET resin. When PET is used as a fiber, it is typically called polyester. The PET bottle was invented by Nathaniel C. Wyeth, a DuPont engineer and brother of American painter Andrew Wyeth. The patent was issued to Wyeth in 1973 and assigned to DuPont. According to the EPA, recycling one pound of PET bottles (that’s about 10 two-liter soda bottles) saves approximately 26,000 BTUs of energy. PET bottles and the sun are helping millions of people in developing countries obtain potable water. Using a system called SODIS (solar water disinfection), inhabitants set water-filled PET bottles in the sun for several hours or days – depending on how much sunlight is available – as a simple but effective means of destroying disease-causing bacteria and gaining safe drinking water. More than 1.5 billion pounds of used PET bottles and containers are collected in the U.S. each year for recycling. PET is the most recycled plastic in the U.S. and the world. A single-serve PET bottle (0.5 liter) is strong enough to hold 50 times its weight in water. Chemists keep finding new ways to make PET lighter without losing any strength. A 2-liter PET bottle that weighed 68 grams in 1980 now weighs as little as 42 grams. The average weight of single-serve 0.5 liter PET water bottle is now 9.9 grams, nearly half of what it weighed in 2000.

Amphora-Aged Cos Wine: New Or Ancient
AMPHORA-AGED COS WINE: NEW OR ANCIENT There is something simply amazing to view a winery making its top wines in a series of earthenware jars. Is there shock-horror? Yes for a technocrat trained on the finer points of grades of stainless steel. But no for someone on a path of discovery to understand just what the practitioners do when there is a choice to return to the roots of winemaking practice. And the use of clay pots has been a natural winemaking event year-on-year in Georgia for as far back as 6000 years BC. Recently a colleague advised me that a 2012 trip to this old world winemaking country included a visit to a monastery using the clay pot containers continuously for 1000 years (a lot of vintages there to build up tartrate!) So I was recently on the path of discovery in Sicily to visit two famous properties using earthenware jars for winemaking and aging (COS in Vittoria) and Cornelissen (on Etna) who ages new wine similarly. There is a space in between with the technology path-that of using oak barrels as storage vessels, and over the past decade used, large (3-5,000 litre) format casks have proved to be valuable aging means for high quality wines. Casks displaced earthenware vessels as they were more practical. However keeping large casks fresh and clean is a never-ending job, and at times capable of going wrong (cask has to be burnt). Also the cask remains practical for making larger volumes of wine, while re-introducing the clay pot makes sense for small parcel winemaking as pot management is a lot simpler than in the 15th century.
