Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Himalayan Gold Here is a riddle for you. What goes from being an insect in the winter to becoming a plant in the summer, and is deemed more precious than gold? Here is the answer, it is Ophiocordyceps Sinensis (O. Sinensis), formerly known as Cordyceps Sinensis and generally called Cordyceps. In Chinese, it is called 冬蟲夏草 (dōng chóng xià cǎo) literally translates as "Winter Worm, Summer Grass" It is also known as "Himalayan gold" or "Himalayan elixir.” O. Sinensis is a parasitic fungus and primarily infects the larvae of certain insects, particularly caterpillars of Thitarodes (ghost moths). The fungus infects the host insect, takes over its body, and eventually grows out of the host's body as a long, slender stalk. Why would this cost more than gold? O. Sinensis is highly valued in traditional Chinese medicine, it is currently traded at a staggering price of USD $20,000 - $40,000 per kilo in the market. It has been used for centuries to address a variety of health concerns, such as boosting energy, enhancing stamina, improving respiratory function, and promoting overall vitality. It is often believed to have adaptogenic properties, meaning it may help the body better adapt to stress and maintain balance. In recent years, O. Sinensis has gained attention in the realm of modern herbal and alternative medicine, and it is available in various forms including supplements, powders, and teas. However, scientific research on its effectiveness and safety is still ongoing, and its use should be approached with caution and under the guidance of a healthcare professional. The Himalayan plateau is the habitat where O. Sinensis thrives, a world of thin air and secluded spaces. Here, the growth of this enigmatic organism demands time—a period spanning over ten days, as it inches ever so slowly toward maturity. In the shadows of this high-altitude haven, the fungus encounters its host, using it as a launching pad for its own life cycle. The fungus invades the caterpillar's body, gradually taking over its tissues, and ultimately, its life. Yet, there's an astonishing twist. As the caterpillar's body succumbs to the invader, it provides the nutrients that O. Sinensis needs to flourish. This fatal symbiosis transforms the caterpillar's remains into fertile ground, giving birth to the distinctive fruiting body. In the right climatic conditions, this metamorphosis culminates in the emergence of the sought-after fruiting body for traditional Chinese medicine which also gaining huge popularity in Western culture. And so, the journey of O. Sinensis continues from the heights of its natural habitat to the bustling markets of the world. Here, the fungus takes on a new role, as it transitions from the wild to the realm of commerce. Revered for its potential health benefits, it's harvested, packaged, and transported to market stalls, where it's sold as a valuable ingredient in traditional medicines, elixirs, and tonics. But this transformation comes with a cost. As demand grows, so does the challenge of sustainability. The very ecosystems that cradle O. Sinensis are vulnerable to over-harvesting, and its rarity only adds to its allure. The collection of O. Sinensis has evolved into a means of sustenance and livelihood for indigenous communities, yet unwittingly, consumers around the world are exploiting this reliance, thereby impacting the overall population and habitat of the species. ←Previous Next→

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Cardboard Boxes Recycling & Disposal ✅ Recyclable: Most clean and dry cardboard boxes (shipping boxes, moving boxes, cereal boxes, etc.) can be recycled. Flatten the boxes to save space in the recycling bin. Remove tape, labels, and staples if possible (small amounts are usually okay). ⚠ Important Notes: Greasy, wet, or food-contaminated cardboard (e.g., pizza boxes) should go in compost (if accepted) or trash. Wax-coated cardboard (like some produce boxes) is generally not recyclable unless specified by your local recycling program. Some areas may require bundling or specific drop-off locations for large amounts of cardboard. ♻ Alternative Reuse Ideas: Use for storage or moving instead of buying new boxes. Shred and use as mulch or compost (if uncoated and non-glossy). Donate large boxes to community groups, schools, or moving services .

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Underneath those patched rags (Boro) resides a heart of golden brocade. My mother taught me a Japanese proverb, "Underneath those patched rags (Boro) resides a heart of golden brocade." (襤褸は着てるが心は錦) The word, "Boro" is a traditional textile practice originating from impoverished rural Japan, particularly among peasants and farmers dating back to the early 1600s. Boro refers to textiles that are worn out, no longer usable, and garments that are old, torn, or patched. Boro textiles were born out of the practical need to extend the lifespan of fabrics and garments in an era where new textiles were not easily attainable for many people. During that era, garments were never discarded; instead, they were recycled persistently across generations. Through layering, stitching, and patching, individuals would mend and reinforce their clothing and other textiles. People employed a traditional stitching technique known as "Sashiko" on linen garments, both to preserve warmth and enhance durability. Over time, these mended and patched areas accumulated, creating the distinctive aesthetic that defines Boro. It is intricately interwoven with family history and memories, gaining indescribable beauty and significance. ** The pictures are vintage boro kimonos and a modern jacket with upcycled-boro garment. ←Previous Next→

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Why Some People Can’t Eat Cilantro: The Science Behind the Controversy Why Some People Can’t Eat Cilantro: The Science Behind the Controversy Cilantro is a divisive herb—some people love its fresh, citrusy flavor, while others claim it tastes like soap. This extreme difference in perception isn’t just a matter of preference; it has a genetic basis. Understanding why cilantro tastes unpleasant to certain individuals sheds light on how genetics, smell, and personal experiences shape our food preferences. The Genetic Link to Cilantro Aversion Studies have shown that an aversion to cilantro is linked to genetics, specifically a group of olfactory receptor genes that influence how people perceive smells. A key player is the OR6A2 gene , which encodes a receptor that detects aldehydes—compounds found in both cilantro and soap. For those with a specific variation of this gene, cilantro's natural aldehydes create a soapy or pungent taste, making it unappetizing. Meanwhile, those without this genetic trait experience cilantro as fresh and aromatic. Cultural and Environmental Influences While genetics play a significant role, exposure to cilantro also affects how people perceive it. Those who grow up eating cilantro in cuisines like Mexican, Indian, or Thai food may develop a tolerance or even a liking for it over time, even if they have the genetic predisposition for aversion. Repeated exposure can help the brain rewire its association with the herb, making it taste less offensive. Can Cilantro Hatred Be Overcome? Some people who initially dislike cilantro find they can tolerate it when it is finely chopped, mixed into dishes, or combined with acidic ingredients like lime juice. Crushing or cooking cilantro can also break down some of the aldehyde compounds, reducing the soapy taste. If you’re one of those who despise cilantro, know that it’s not just in your head—it’s in your genes. However, exposure and preparation methods may help make cilantro more palatable over time. Whether you love it or hate it, cilantro remains one of the most fascinating examples of how genetics influence our taste perceptions. ←Previous Next→

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards How to Recycle and Dispose of Sponges Most kitchen sponges are not accepted in curbside recycling because they are small, often contaminated with food residue, and may combine foam, plastic fibers, adhesives, and abrasive scrub layers. The best option depends on the sponge’s material and condition. Before disposal, use a sponge as long as it remains safe and effective. Replace it when it is falling apart, has a persistent odor after cleaning, or cannot be adequately cleaned. Identify the sponge type Sponge type Typical material Best end-of-life option Standard synthetic sponge Polyurethane foam, plastic fibers, abrasive scrub layer Specialty recycling if available, otherwise trash Two-sided scrub sponge Foam plus plastic scouring pad Specialty recycling if accepted, otherwise trash Cellulose sponge Plant-based cellulose, often wood pulp Compost only if it is confirmed 100% natural and free of plastic layers or additives Natural sea sponge Natural marine sponge Compost only if clean and untreated, or dispose according to local rules Loofah or plant-fiber scrubber Dried loofah, coconut fiber, or other plant material Compost only if no plastic, adhesive, coating, or synthetic thread is present Sponge with a plastic scrubber, foam core, or synthetic fabric Mixed materials Trash or specialty recycling, not compost Do not assume that a sponge labeled “natural,” “biodegradable,” or “eco-friendly” is compostable. Read the package and look for a clear material description. A sponge with a plastic scouring layer, polyurethane foam, synthetic fibers, adhesives, or antimicrobial treatment should not go in a home compost pile. Specialty recycling TerraCycle operates brand-sponsored and paid programs for hard-to-recycle materials. Program availability, accepted brands, accepted sponge types, drop-off locations, and mailing requirements can change, so search TerraCycle’s current program directory before collecting or shipping sponges. Some Scotch-Brite products contain recycled content. For example, 3M states that its Scotch-Brite Heavy Duty and Greener Clean scrub sponges use 100% recycled scrubbing fibers. Recycled content does not necessarily mean the used sponge itself is recyclable through curbside collection. Before using a specialty program: Confirm that the program is active in your country or area. Confirm it accepts the exact sponge, scrub pad, or cleaning product. Follow cleaning, drying, packaging, and shipping instructions. Do not send wet, moldy, hazardous, or heavily contaminated material unless the program explicitly allows it. Check whether the program is free, brand-sponsored, or requires purchase of a Zero Waste Box. Repurpose before disposal A worn sponge can still be used for lower-contact cleaning tasks before disposal: Scrub outdoor furniture, garden pots, grill tools, or trash cans. Clean tires, wheel wells, tools, or muddy shoes. Use for paint, stain, craft projects, or applying glue. Cut into small pieces for cushioning fragile items during storage or moving. Use pieces as drainage material in some non-food decorative planters, if appropriate. Do not repurpose a sponge that is moldy, heavily soiled, falling apart, or contaminated with chemicals. Composting natural sponges Only compost a sponge if it is clearly made from 100% natural, untreated plant-based material or a natural sea sponge, and if it has no plastic scrub pad, synthetic stitching, foam, adhesive, antimicrobial coating, or chemical treatment. For eligible natural sponges: Rinse out soap and food residue. Let the sponge dry completely. Cut it into small pieces. Add it to an active compost pile in small amounts. Do not use compost containing a heavily soiled sponge on food crops unless you are confident it was free of hazardous cleaners or contaminants. Cellulose sponges made from plant materials can be compostable, but common two-sided sponges with plastic scouring pads are not. Cutting eligible cellulose material into smaller pieces can help it break down more quickly. When trash is appropriate Place a sponge in household trash if it: Is made from polyurethane foam or other synthetic materials Has an attached plastic scouring pad Contains mixed materials that cannot be separated Is moldy, heavily contaminated, or chemically soiled Cannot be accepted by a specialty recycling program Is not clearly identified as 100% natural and compostable Bag loose sponge fragments if needed so they do not scatter during waste collection. Reduce future sponge waste Choose durable, washable cleaning cloths for routine wiping. Use washable dish brushes with replaceable heads. Consider 100% cellulose, loofah, or plant-fiber scrubbers only when their end-of-life claims are clearly supported by the manufacturer. Avoid products with unnecessary packaging or mixed plastic layers. Let sponges dry between uses to help extend their usable life. Safety and Legal Notice This guide is for educational purposes only. Recycling and composting acceptance depends on the sponge’s exact materials, local waste rules, and specialty-program requirements. Confirm instructions with the manufacturer, recycler, TerraCycle program, or local composting facility before participating. Do not compost sponges that contain synthetic foam, plastic scrub pads, adhesives, coatings, antimicrobial chemicals, or unknown materials. Do not use heavily soiled or chemically contaminated sponges in gardening, composting, or food-related tasks. Wash hands after handling old sponges and replace sponges that are moldy, deteriorating, or cannot be cleaned effectively.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Rapid Evolution: The Impact of Ivory Poaching on Tuskless Elephant Population Rapid Evolution: The Impact of Ivory Poaching on Tuskless Elephant Population The trade for elephant tusks had long been lucrative, reaching staggering prices of $2100 per kg in foreign markets at the peak trading. These tusks, deeply embedded in elephants' skulls, often led to excruciating deaths for the animals. The Mozambican Civil War, spanning from 1977 to 1992, witnessed a dramatic escalation in elephant poaching driven by the need to fund the war. The consequences were devastating for the elephant population, which faced near extinction. Before the conflict, approximately 2000 elephants roamed the Gorongosa region. However, the intensity of poaching during the war resulted in a catastrophic loss, with around 90% of the elephant population wiped out. A recent study has unveiled significant evolution among elephants in Mozambique's Gorongosa National Park, where rampant ivory poaching during the civil war has led to a notable increase in the number of tuskless female elephants. Their findings, published in the journal Science, revealed that the pressure of ivory poaching favored tuskless elephants, particularly females, resulting in a genetic shift within the population. The percentage of tuskless females was 18% in the Gorongosa National Park before the war. The tuskless number jumped up to 50% during the war, and 33% after the conflict ended. The researchers found that the surviving tuskless females passed on this trait to their offspring, resulting in about half of their daughters being tuskless. Additionally, genetic analysis revealed that a dominant gene on the X chromosome likely determines tusklessness in female elephants and may lead to the early death of male embryos. Furthermore, the tusks are vital for African elephants. They are used for digging soils for water, self-defense, stripping trees, lifting objects, and competing for mating. The absence of tusks can affect their behaviors such as eating and mating. The study underscores the profound influence of human activities.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Pigment Previous Next Improving Plastic Recycling Rates: The Role of Pigments To improve plastic recycling rates, it is essential to examine the factors influencing the recyclability of different plastics. This article focuses on analyzing the role of pigments in plastics, which play a critical part not only in coloring but also in influencing the overall properties and recyclability of plastics. What Are Pigments? Pigments are insoluble particles, either organic or inorganic, blended with polymers to provide specific colors to plastics. While their primary purpose is to color plastics, pigments also contribute important properties such as heat resistance, UV protection, and durability. Pigments are typically classified into two main categories: Organic Pigments : These are carbon-based compounds known for producing vibrant colors but may be less durable than inorganic pigments in certain conditions. Inorganic Pigments : Made from metallic compounds, such as titanium dioxide or iron oxide, inorganic pigments tend to offer superior stability, better heat resistance, UV protection, and longevity. Performance Properties of Pigments in Plastics Weatherability or Aging : Definition : The ability of pigments and plastics to resist degradation when exposed to environmental factors like sunlight, humidity, temperature changes, and pollutants. Organic vs. Inorganic : Inorganic pigments tend to perform better in terms of weatherability due to their inherent stability, while organic pigments are more prone to fading or degradation, particularly under UV light. Light Fastness : Definition : The ability of the pigment to retain its color when exposed to light, especially UV light. Organic vs. Inorganic : Organic pigments generally have lower light fastness compared to inorganic pigments, meaning they fade more quickly under sunlight. Flexibility, Warping, or Nucleation : Definition : Flexibility refers to a material's ability to bend without cracking, while warping refers to deformation due to heat or stress. Nucleation is the process of particle formation in polymers. Impact of Pigments : While pigments are not primarily responsible for flexibility or warping, they can indirectly affect these properties. For example, pigment particles may influence the polymer's crystallization, affecting flexibility and deformation. However, these properties are more closely related to the polymer matrix and additives. Transparency : Definition : The ability of a pigment to allow light to pass through it, impacting the opacity or translucency of the final product. Organic vs. Inorganic : Organic pigments are often more transparent, while inorganic pigments can be either transparent or opaque depending on the compound used. Comparison of Organic and Inorganic Pigments in the Color Orange Organic Pigments: Composition : Organic pigments contain carbon atoms, derived from natural or synthetic sources. They produce vibrant and intense colors, such as orange. Challenges : Organic pigments may struggle with mixing and dispersion, leading to inconsistencies or clumping in plastics. Cost : Organic pigments tend to be more expensive due to their production complexity and vibrant color. Performance : Organic pigments may not offer the same durability as inorganic pigments, particularly under UV light or weathering conditions. Inorganic Pigments: Composition : Inorganic pigments are derived from minerals, metals, and metal oxides. They are more stable and resistant to environmental degradation. Advantages : Inorganic pigments provide better weatherability, light fastness, and heat resistance. For orange, pigments like iron oxide and cadmium-based pigments are often used due to their durability. Toxicity : Some inorganic pigments, especially those with heavy metals like lead and cadmium, can be toxic. However, many modern inorganic pigments are lead-free, and stricter regulations have led to safer alternatives. Dispersion : Inorganic pigments are easier to disperse in resins and plastics compared to organic pigments, providing stable and consistent color in the final product. Titanium Dioxide : One of the most commonly used inorganic pigments, titanium dioxide is odorless, non-toxic, highly durable, and provides excellent opacity and brightness. It is widely used in applications requiring brightness, opacity, and UV resistance. Other Unique Pigments Carbon Black : Versatility : Carbon black is widely used in thermoplastic and anti-static applications, such as automotive fuel caps, pipes, and in plastics, films, adhesives, and paints. Color Strength : Known for providing deep black tones with excellent color strength and cost-effectiveness. UV Resistance : Carbon black helps protect plastics from UV degradation. Oil Absorption and Particle Size : Its small particle size and high oil absorption properties contribute to its superior durability and color quality. Versatility : Carbon black is versatile and can also be used for color modification or tinting. Aluminum Pigments : Application : Used to introduce metallic effects and enhance the aesthetic qualities of products, particularly in plastics, coatings, and paints. Aluminum pigments provide shiny, reflective properties, adding metallic functionality to polymers. Fluorescent Pigments : Unique Properties : Fluorescent pigments can absorb and re-emit light, creating vibrant glowing effects. These pigments are commonly used in applications requiring high visibility or aesthetic appeal, such as safety signs, paints, and plastic products. Recycling Challenges with Black and Pigmented Plastics Carbon Black and Recycling : Sorting Issues : Carbon black presents challenges in plastic sorting for recycling. The pigment's ability to absorb near-infrared (NIR) light prevents sorting sensors from detecting black plastics, leading to these materials being misclassified and sent to landfills. General Impact on Darker Plastics : The problem extends beyond carbon black. Other darker pigments also cause sorting issues, leading to many dark-colored plastics being discarded or landfilled. Brightly Colored Plastics (e.g., PET) : Contamination Issue : Brightly colored plastics, such as PET (polyethylene terephthalate), can contaminate recycling streams, especially clear or white PET. These vibrant colors complicate the recycling process and reduce the quality of the final recycled material.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Eco-Friendly Brewing The pervasive presence of these tiny pollutants in seemingly innocent items like tea bags and coffee pods is something unexpected for many. Despite the predominant use of natural plant fibers in their composition, certain brands resort to sealing these products with polypropylene to prevent paper filters from falling apart in hot water. Disturbingly, recent research from the National Health Institutes uncovered unsettling statistics: a single cup of tea brewed with a plastic tea bag contained a staggering 11.6 billion microplastics and 3.1 billion nanoplastics. This revelation prompted me to explore zero-waste alternatives. Here are unique and effective replacements. Organic Hemp Cloth Filter Bags: Organic hemp cloth as a filter material presents a promising solution. Hemp is an annual plant and grows relatively fast. Additionally, hemp cultivation demands only half the water required for cotton. While organic cotton is also an excellent alternative, hemp boasts superior durability, potentially outlasting its counterparts with frequent use. The added advantage lies in hemp's natural antimicrobial properties, resisting mold and mildew and making it a hygienic cloth option. As for the maintenance of these bags, they need to be washed thoroughly with (ideally unscented) soap after use to keep them mold-free and the flavor of drinks fresh. Image By 39 Arita Micro-Porous Ceramic Filters: Intriguingly, porous ceramic filters featuring countless micron-wide holes have emerged as an alternative. Several brands offer variations of this technology, with overall positive reviews attesting to improved coffee or tea flavor. However, the inconvenience of cleaning this delicate filter can be a challenge depending on your patience level. While rinsing the filter with water post-use is a common practice, coffee grinds and oil may gradually build up in the pores over time. The care instructions (for a few of the ceramic filter products) state when the filter clogs, heat it in the oven or with the flame for 15 minutes to burn off the residue. Despite the maintenance, many enthusiasts appear to enjoy brewing coffee with the filter. In the meanwhile, a few proponents argue that ceramic filters excel in steeping tea since tea leaves are larger and unlikely to cause such clots. Metal Filters: This option stands out for its durability and the length of the product lifespan among all three choices. Unlike their counterparts, metal pour-over coffee filters allow certain oils and sediment to find their way into your cup. These elements contribute to the luxurious flavors cherished by many coffee lovers. For those who savor the sweet and robust nuances of coffee, metal pour-over filters are often the preferred choice. However, while cloth, paper, and ceramic filters adeptly capture cafestol, an oil associated with elevated cholesterol levels found in coffee, standard metal filters may not offer the same level of filtration. Anyway, the likelihood of elevated serum cholesterol levels is also influenced by the quantity of coffee consumed and an individual's sensitivity to caffeine. Additionally, it's worth noting that metal filters might subtly influence the taste of coffee or tea by leaving their mild metallic flavors. These are brilliant products for promoting zero-waste living. However, it is crucial to also consider the carbon footprint of maintenance throughout the product's life cycle including gas, water, and soap when choosing alternatives. Keep in mind that embracing sustainable living may occasionally demand some inconvenience, but the long-term benefits make it worthwhile! ←Previous Next→

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Polymer Structure Previous Next Plastics can be classified into two main categories based on their polymer structure: thermoplastics and thermosetting plastics. Thermoplastics: Recyclability: High. Thermoplastics can be melted and remolded multiple times without undergoing significant chemical changes. This makes them generally easier to recycle. Examples include PET, HDPE, PVC, LDPE, PP, and PS. Examples: PET (Polyethylene Terephthalate) Commonly used in beverage bottles and food containers. HDPE (High-Density Polyethylene) Found in milk jugs, detergent bottles, and piping. PVC (Polyvinyl Chloride) Used in plumbing pipes, electrical cable insulation, and medical devices. LDPE (Low-Density Polyethylene) Used in plastic bags, squeeze bottles, and film wrap. PP (Polypropylene) Found in packaging, textiles, and automotive parts. PS (Polystyrene) Used in foam products like Styrofoam, disposable cutlery, and CD cases. Thermosetting Plastics Recyclability : Low . Thermosetting plastics undergo a chemical change when heated, making them rigid and unable to be remelted and reshaped. This makes recycling these plastics more challenging. Common examples include epoxy resins, phenolic plastics, polyurethane, and melamine formaldehyde. Examples: Epoxy Resins Used in adhesives, coatings, and composite materials. Phenolic Plastics Found in electrical components and heat-resistant objects. Polyurethane Used in foam products, coatings, and adhesives. Melamine Formaldehyde Used in kitchenware, laminates, and adhesives. References: Polymer Structure: Andrady, A. L., & Neal, M. A. (2009). "Applications and societal benefits of plastics."
