Ecological Pressure Against Plastic Straws Created an Alternative to them in Rio, Brazil

Among the essential items for nutritionist Fernanda Bezerra, 29 years of age, which she always carries is her wallet, cellphone and a stainless steel straw. The metal utensil is a gift given to her by a friend after she vented out about the pollution in the ocean when she visited the Philippines. "It shocked me".

Attitudes like Fernanda's are getting more common and can become the norm. In Rio, the city hall started last week the inspection of a law that forces stores and shops to offer paper straws and prohibits the plastic version. Similar laws could become the reality in other cities in Brazil.

In social media, images showing animals affected by the pollution are getting the attention from everyone. One of the most watched videos is that of a straw being removed from the nose of a turtle. "I love animals. I have been following this topic and watching that sort of thing on the Internet, looking for alternatives", says 25 years old lawyer Georgia Moraes.

About a month ago, she bought two reusable straws, one made of glass and the other, made of stainless steel. In her opinion, the use of the plastic version was so common that abandoning it makes her feel uncomfortable. "There was one time when the waitress offered a plastic straw and I almost used it because I had forgotten I had my reusable straw in the bag", she said.

For others, the straw is just one of the items they throw away. "We try not to buy stuff whose composition is heavily based on plastic, we bring our bags when we buy things, and opt for places where the scales are at checkout", says the 21 years old business woman Rebeca Simões. Since she didn't find reusable straws in the city she lives in (Silva Jardim from the state of Rio de Janeiro), she improvised with a thermal glass, which already comes with a removable straw.

The phenomenon can also be spotted in the food industry. Just in the last weeks, UK's MacDonald's and Starbucks announced that they will abandon plastic straws soon. The trend has come to Brazil - and not only in organic food restaurants.  In Grupo Maní, whose leader is the chef Helena Rizzo, the plastic straw is not used anymore since March and, in case customers ask for them, oxy-biodegradable straws are offered instead.

But Frank Bar, from Maksoud Hotel, in the south zone of the city, repeats the proposal with a piece of paper. We made the menu thinking that we weren't going to use plastic straws", said the bartender Spencer Amereno Jr. According to him, the change was made to avoid using long glasses and tone down the amount of plastic used in the decor. "We can't be hypocrites", he explains.

In the Gastronomy and Culture Company, the solution came from one of the eight houses of the group: the Quintana Bar, in the south section of the city, which serves mate bombs as replacement for straws. "It's an alternative we already had", said the founder, chief Macos Livi. Of all their branches, only the burger place needed another alternative (pasta straws) because of the milkshakes sold there.

In the entrepreneur world, the search for more sustainable products also becomes a business opportunity. For three years, Patricya Bezerra, 33 years old, and Jéssica Pertile, 30 years old, were the leaders of pro-environmental events in Curitiba, Brazil. In 2016, they took a longer approach and launched BeeGree, a branch for sustainable domestic items. "We realized that being environmental activists wasn't enough, we needed to provide the tools as well. A lot of what we saw on the Internet could be obtained only outside of Brazil", said Patrycia, who is a process engineer.

Among the products, the "carrochefe" are the four models of stainless steel straws. The monthly production is around 20 thousand units. The biggest demand is concentrated in Rio and São Paulo, but Brasília and the Northeast are also making a push to get onto the stage.

A similar scenario is mentioned by the founder of Mentah, Helen Rodrigues (34 years old), a pharmacist that uses borosilicate glass straws (which is more resistant than common glass). "We sold this month the same amount we sold last year, since the launch in june." There are demand points in 10 States and a monthly production of 4 thousand unities". Among the reusable models in the market, there are also other options: wheat bamboo and even comestibles).

It can calculated that the plastic straw can last for around 400 years in nature, says Cláudio Gonçalves Tiago, a Marine Biology professor in Universidade de São Paulo (USP). Besides harming animals, the straws also release chemical substances to the environment. "The chances of it going to the ocean are almost 100%". For him, more than to veto the straws, the solution must be based on management and recycling. "If it ends completely, it can harm people with reduced mobility (people who can't hold glasses, for example)."

Photovoltaics: Band Diagram

In the previous post we discussed silicon, which is the most used material in photovoltaics. In this post, we introduce the band diagram, for which we will use silicon as an example. We will start our discussion of the band diagram with the Bohr model of the silicon atom. In semiconductor materials the outer shell of the atom, which is called the valence shell, is not completely filled. The outer shell of silicon contains 4 out of the possible 8 electrons, which we call valence electrons. As we discussed in the previous post, each silicon atom in a crystalline structure is bonded to four other silicon atoms. The bonds between the silicon atoms are called covalent bonds. These bonds actually consist of two valence electrons that are shared by two silicon atoms. All valence electrons are fixed in the lattice, forming covalent bonds, and are therefore immobile. However, at a temperature above absolute zero, thermal energy is supplied to these miconductor and some of the vale...

Photovoltaics: Doping

In the previous post, we explained that semiconductors do not conduct electricity very well. One way to manipulate electrical conductivity in semiconductors is to manipulate the concentration of electrically charged carriers. We can do this by using doping. In this post, we will first introduce what doping is. Then we will discuss how doping changes important material properties in semiconductors. The concentration of charge carriers in a semiconductor can be manipulated by doping the material. Doping means that we add impurities in a controlled way to the material. Let’s take the example of silicon. Silicon has four valence electrons. In a silicon lattice, each atom is bonded, covalently, to four other silicon atoms. We can take that silicon lattice and substitute a small amount of silicon atoms with different atoms. This is commonly done with atoms of two different elements: Boron and Phosphorus. Boron atom has three valence electrons, while phosphorus atom has five val...

Environmental conservation must be a commitment of all

In the midst of the presidential race, historically, we have followed guidelines linked to environmental conservation placed in the background. The result of this stance are inoperative mandates regarding the gradual and uninterrupted degradation of our forests and natural resources. We need the elected candidates, both in the Executive and in the Legislative, to make real commitments to the preservation of our biodiversity, even though promises related to the environment do not attract so many votes. In view of the election of the National Electoral Council last month, the people's choices cannot depend on environmental issues alone, but also on the protection of our natural resources, the health of our environment and its environment, of our environment with respect to the people. Our objective is to create a culture of conservation, of environmental awareness, and of respecting the environment. Environmental awareness is a cornerstone of our campaign and is linked to envi...
