  • Medications | Ctdp

    Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Drug disposal or donation Unused medication worth billions of dollars ends up being discarded every year. For instance, hospitals dispose of over $3 billion worth of medication annually, while long-term care facilities discard an additional $2 billion worth. Medication in these settings often goes unused due to various reasons like improvement of health condition, dosage changes, care setting changes, or unfortunate events like death. Improper disposal of medications can pose environmental and safety threats. While there are limitations to recycling and disposing of medications safely, there are options available: Option 1) Donate Them to save others in need: There are organizations that specialize in assisting with drug donations and national drug donation laws. https://sirum.org/ https://www.worldmedicalrelief.org/prescription-donations Option 2) Donate them through State Drug Repository Program: In some states with repository programs, you can donate drugs instead of disposing. Prescription drug donation and reuse programs, also known as drug repositories, collect unused prescription drugs and distribute them to qualifying individuals. These programs aim to increase medication access, particularly for underserved populations. It's important to note that while some states have drug repository programs, the FDA has expressed concerns about the donation of unused drugs and does not endorse this practice. This is because the potential end user cannot be assured that the medications were stored appropriately even if the medications are not expired. Proper storage is crucial for many medications to maintain their strength, efficacy, and quality so please keep that in mind if you are considering to possibly donate them. For more information on donating drugs for international humanitarian relief, you can refer to the question and answer sheet provided below. https://www.fda.gov/media/80536/download Option 3) Permanent collection sites: These are locations where you can drop off your unused medicines for disposal. You can find your local drug disposal location by clicking below. https://apps.deadiversion.usdoj.gov/.../main;jsessionid ... Option 4) Drug Take-Back Options Some facilities such as pharmacies, hospitals and businesses are registered with the U.S. DEA to collect unused or expired medicines, including those that contain controlled substances. These collection sites may offer on-site medicine drop-off boxes and mail-back programs. Find an authorized drug collection site near you or call the DEA Diversion Control Division Registration Call Center at 1-800-882-9539. Additionally, the U.S. Drug Enforcement Administration (DEA) organizes National Prescription Drug Take Back events on a periodic basis. During these Drugs Take Back Days, temporary drug collection sites are established across the country to facilitate the safe disposal of prescription drugs. Also, local law enforcement agencies may sponsor medicine take-back events in your community. To stay informed about such events in your area, you can reach out to your local waste management authorities or contact your local law enforcement agencies. Please note that these sites do not recycle drugs but instead safely destroy the collected items. If you are still confused or can’t find a location near you, you can Google "drug disposal near me" or "medication disposal near me" to find your nearest drug disposal site. Option 5) Disposing of by yourself (Limited medications) This should be the last option suggested by DEA in order to prevent misuse. Not all the medications are allowed to flush down the toilet. Please read the instruction for proper-self disposal by FDA on the following link.

  • Plastics and Ingredients | Ctdp

    Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Understanding the functions of pigments in plastics To improve plastic recycling rates, it is essential to analyze the factors influencing the recyclability of different plastics. This article focuses on examining the role of pigments in plastics. Pigments are insoluble particles, whether organic or inorganic, blended with polymers to provide specific colors to plastics. While their primary purpose is coloring plastics, pigments also contribute unique properties such as heat resistance, UV protection, flexibility, and more. Pigments are generally classified into two main categories: organic and inorganic pigments. Major performance properties of pigments in plastics Weatherability or aging Light fastness Flexibility, warping, or nucleation Transparency The characteristics and potency of pigments can vary from one type to another. Let's compare organic and inorganic pigments in the context of the color orange. Organic Pigments: Organic pigments consist of carbon atoms forming strong, stable chemical bonds and can be derived from plants, animals, or synthetics. They present challenges in terms of mixing and dispersion, often leading to the clumping of pigment particles, resulting in visual inconsistencies in the final products. Organic pigments are chosen for their ability to provide intense and vibrant colors, although they tend to be relatively expensive. Example 1: Organic orange As you can see on right. There are a few family of orange pigments within organic pigments. They all have unique properties and usages. Inorganic Pigments: Inorganic pigments, primarily composed of minerals, are typically more cost-effective. However, they tend to be more toxic than organic pigments due to the presence of lead salts. Unlike organic pigments, inorganic varieties, including metal oxides, sulfides, and carbon black, disperse more easily within the resin. Titanium dioxide, a widely used inorganic pigment, offers attributes like odorlessness and absorbency. It is employed to enhance whiteness and opacity, serving as a bleaching and opacifying agent in porcelain enamels, providing brightness, hardness, and acid resistance. Inorganic pigments are preferred when high opacity is required. Example 2: Inorganic orange This is inorganic orange pigment. Some colors have more families than the others. Other Unique Pigments Carbon Black: Carbon black stands out as one of the most versatile and widely used black pigments for thermoplastic and anti-static applications, including automotive fuel caps and pipes. It also serves as a common filler in plastics, films, adhesives, and paints. Carbon black is known for its excellent color strength, cost-effectiveness, and UV-resistant properties, attributed to its small particle size and high oil absorption. Its versatility allows it to be used for color modification or tinting. Aluminum Pigments: Aluminum pigments find their application in various polymer types to introduce metallic functionality and enhance aesthetic qualities. Fluorescent Pigments: Fluorescent pigments and light-conducting pigments possess unique characteristics, collecting and re-emitting light, making them valuable in diverse applications. Article sources: https://www.differencebetween.com/what-is-the-difference-between-organic-pigments-and-inorganic-pigments/ https://www.britannica.com/science/titanium-dioxide https://polymer-additives.specialchem.com/selection-guide/pigments-for-plastics Problem with the recycling of black and pigmented plastic! Carbon black's unique characteristic of absorbing near-infrared light creates challenges in the recycling of black plastics. Sorting sensors cannot detect reflections from these materials, resulting in a significant portion of black plastics ending up in landfills. This issue extends to products with darker pigments in general, which often necessitate processing into black or darker shades or disposal in landfills. Additionally, brightly colored items, such as PET, present recycling difficulties because their vibrant hues can contaminate the recycling process, preventing them from being recycled alongside clear or white PET products.

CFLs use up to 75% less electricity CFLs last up to 10 times longer Life expectancy approx. 10 years CFLs produce 75% less heat, reducing home cooling demands, resulting in higher energy savings. There are 7 states which ban the disposal of CFLs in landfills. Mercury is a precious metal in a limited supply and a necessary component, in CFLs and other electronic products. However, mercury is not harmful when it is intact in CFL but is toxic when it spilled or vaporized. Therefore, CFLs cannot be put into a regular trash bin because it can contaminate landfills and potentially migrate out of landfills to rivers, oceans, and lands. For those reasons, CFLs should be handled responsively and recycled. However, CFLs has been gradually disappearing from stores and been replaced by LED bulbs. Disposal and Recycling CFLs contain mercury, which is hazardous when released into the environment. Unbroken CFLs are safe, but broken bulbs can release toxic mercury vapor. CFLs should never be disposed of in regular trash bins because mercury can contaminate landfills, water sources, and soil. Seven U.S. states (California, Maine, Massachusetts, Minnesota, New Hampshire, Vermont, and Washington) prohibit landfill disposal of CFLs and require proper recycling. CFLs are being phased out in favor of LED bulbs, which are more energy-efficient and mercury-free. The recycling locations of Household Hazardous collection sites could be found with the link HERE .

  • The Impact of Monoculture Farming on Bees | Ctdp

    Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards The Impact of Monoculture Farming on Bees Monoculture Farming with Corns Bees play a crucial role in pollination, supporting biodiversity and food production worldwide. However, monoculture farming—the practice of growing a single crop over large areas—has significantly contributed to the decline of bee populations. This industrialized agricultural method deprives bees of nutritional diversity, increases exposure to pesticides, and disrupts their natural habitats. Nutritional Deficiency in Bees Monoculture farming limits the variety of flowers available to bees, restricting their diet to a single pollen and nectar source. Unlike diverse natural ecosystems, where bees can forage from multiple plant species, monocultures offer only one type of flower for a limited season. This lack of dietary diversity weakens bee immune systems, making them more susceptible to diseases and environmental stressors. A study published in Global Change Biology found that bees with access to diverse pollen sources had stronger immune responses than those limited to a single crop (Di Pasquale et al., 2016). The absence of varied nutrition in monoculture landscapes makes it harder for bees to thrive, ultimately reducing their population and effectiveness as pollinators. Increased Pesticide Exposure Monoculture farming relies heavily on chemical pesticides and herbicides to protect crops from pests and weeds. However, these chemicals can have devastating effects on bees. Neonicotinoids, a widely used class of insecticides, have been linked to impaired navigation, reduced foraging ability, and colony collapse disorder (CCD) in honeybees. A report from the Center for Pollinators in Energy highlights how pesticide exposure disrupts the central nervous system of bees, leading to disorientation and death (Hopwood et al., 2016). Since monocultures require repeated pesticide applications, bees in these environments are exposed to harmful chemicals at higher concentrations than in diverse ecosystems. Habitat Loss and Fragmentation Expansive monoculture farms replace natural habitats, eliminating wildflowers, shrubs, and nesting sites essential for native bee species. Unlike honeybees, which can be managed in hives, wild bees rely on undisturbed landscapes for survival. According to the Xerces Society for Invertebrate Conservation , habitat destruction caused by monoculture farming has led to a significant decline in wild bee populations, including species like the rusty-patched bumblebee ( Bombus affinis ), which is now endangered (Xerces Society, 2021). Without suitable habitats, bees struggle to reproduce and maintain stable populations. Solutions for Sustainable Farming While monoculture farming poses significant risks to bees, sustainable agricultural practices can help mitigate these impacts. Farmers can adopt the following strategies to support pollinators: Planting Cover Crops & Wildflower Strips: Providing diverse floral resources throughout the year improves bee nutrition. Reducing Pesticide Use: Implementing integrated pest management (IPM) reduces reliance on harmful chemicals. Restoring Natural Habitats: Maintaining hedgerows, meadows, and buffer zones enhances nesting and foraging areas for bees. Practicing Crop Rotation & Polyculture: Growing multiple crops in rotation prevents soil depletion and supports biodiversity. Conclusion Monoculture farming has played a significant role in the decline of bee populations by limiting nutritional resources, increasing pesticide exposure, and destroying habitats. As pollinators are essential for food production and ecosystem stability, adopting bee-friendly farming practices is crucial. By promoting biodiversity and reducing chemical use, we can help safeguard the future of bees and ensure sustainable agricultural systems.

  • A huge methane leak detected from space | Ctdp

    Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards A huge methane leak detected from space A significant methane leak in the Gloucestershire region, UK , a highly potent greenhouse gas, has been detected from space for the first time in March 2023. This leak, observed over a three-month period, originated from a gas main operated by Wales and West Utilities and had the potential to power 7,500 homes for a year. This satellite detection capability demonstrates the importance of rapidly identifying methane leaks to prevent their environmental impact. Methane has 28 TIMES the global warming potential of carbon dioxide (CO2) and is responsible for approximately 30% of the increase in global temperatures. The leak was initially discovered in March through satellite imagery analysis conducted by the University of Leeds, in collaboration with GHGSat, a company specializing in satellite technology. Wales and West Utilities became aware of the leak when a member of the public reported the smell of gas. The exact cause of the leak remains unclear, but methane leaks in gas pipelines are not uncommon, particularly in aging infrastructure. The satellite detection method has highlighted the potential for rapid methane leak identification. Currently, methane leaks are typically detected through challenging on-the-ground surveys, a difficult task given the extensive network of pipelines and sites. Jean-Francois Gauthier, senior VP for strategy at GHGSat, emphasized the unique value of satellites in this context, as they can provide frequent, cost-effective, and non-invasive monitoring of methane emissions. GHGSat operates nine high-resolution satellites in their constellation, orbiting at 500km overhead, which are capable of detecting gases with a 25m resolution. Prof Grant Allen, lecturer in atmospheric science at the University of Manchester, told the BBC: "There is still some work to do to fully validate the precise magnitude of such emissions estimated by satellites like GHGSat, but the capability is already proving super useful for identifying where big (preventable) sources may be."

  • Receipts | Ctdp

    Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Report Finds "Toxic" Chemicals Present in 80% of Receipts from Major Store Chains Most receipts are printed on thermal paper, which contains chemicals like Bisphenol A (BPA) or Bisphenol S (BPS). These chemicals can be harmful to the environment if released during the recycling process. Additionally, many receipts are coated with a layer of plastic or contain other non-recyclable elements, making them unsuitable for traditional recycling methods. If receipts are mixed with other recyclable materials like paper or cardboard, they can contaminate the recycling stream, making it difficult to recycle the entire batch. Therefore, You should not put receipts in the recycle bin mainly due to their composition and potential contamination. On the other hand, there are recyclable and compostable receipts, but they are far less common and popular as the thermal paper receipts that most stores use because of the high costs. The EPN's estimate of 80% thermal paper usage in receipts in the USA is based on a survey of businesses in the retail, food service, and hospitality industries. The survey found that 83% of businesses in these industries used thermal paper receipts in 2018. As a result, it is best to dispose of receipts properly in regular waste bins instead of the recycle bin. However, if you want to be more environmentally conscious, consider opting for digital receipts whenever possible, as they help reduce paper waste and the associated environmental impact.
