Each year, about 250 billion to-go cups that serve coffee and tea from places like Starbucks and McDonald's are produced to satisfy the world's love for hot drinks on the run. These paper-based cups have the inside surface covered with plastic to prevent water from escaping, and keep water from being absorbed into the material, but that also removes any opportunity for the cups to be biodegradable (可生物降解的).
The materials that created these cups of goodness and convenience are recyclable, but only if separated. In addition, the demand for such resources is low, so they are worth next to nothing.
In response to this great challenge, NextGen Consortium, a multi-year partnership led by Starbucks and McDonald's launched their first big initiative (倡议)—NextGen Cup. The first step in NextGen Cup was an open competition where participants presented ideas for sleeves, cups, lids and other parts of the hot-cold paper-based takeaway coffee cup that would make it reusable, recyclable, or biodegradable, to finally be widely used. 12 winners, announced in 2019, shared a prize of $ 1 million, as well as personalized growth, and support from members of NextGen Consortium.
Later, they launched two pilot programs at independent coffee shops in California. In one case, customers were given "smart" reusable cups made mostly from recyclable plastic. They then could drop their empties into collection containers at key locations, for washing and reuse. These cups were printed with RFID chips or QR codes, through which coffee shops can know where there is the greatest need for collection containers and how many are not using them.
To reduce coffee cup waste, Cup Club is already replacing millions of takeaway cups in the UK, while Recup in Germany, has performed a deposit system (押金系统) that simply adds a small extra fee to any coffee cup which is returned to the buyer after the cup is deposited in any registered collection point.
Before going outside in the morning, many of us check a window thermometer (温度计) for the temperature. This helps us decide what to wear.
{#blank#}1{#/blank#}. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don't feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale. Both systems use the freezing and boiling points of water as their guide. {#blank#}2{#/blank#}.
The most common kind of thermometer is made with mercury inside a clear glass tube. As mercury (or any other liquid) becomes hot, it expands. As it gets colder, it contracts. That is why on hot days the mercury line is high in the glass tube. {#blank#}3{#/blank#}.
First, take a clear glass juice bottle that has a cap; fill the bottle with colored water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw through the nail hole.
{#blank#}4{#/blank#}.
Finally, place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.
{#blank#}5{#/blank#}. As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
A. Now that you know this rule you can make a thermometer of your own that will work. B. People use thermometers which are made by themselves when travelling around the world. C. We use and depend on thermometers to measure the temperature of many other things in our daily lives. D. The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher. E. Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. F. Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal them together. G. They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degree and boils at 100 degrees. |
