What is plastic and a history of it
Plastics are an integral part of our daily lives, from water bottles to high-tech medical equipment.
Plastic is a synthetic or semi-synthetic material that can be molded into almost any form. It is made from polymers, which are long chains of molecules that can be derived from natural resources such as cellulose or from synthetic materials like petrochemicals.
The history of plastics can be traced back to the 19th century, when scientists and inventors began experimenting with new materials to replace traditional ones like wood and metal. One of the first plastics was Parkesine, invented by Alexander Parkes in 1856, which was made from cellulose. In 1907, Belgian-born Leo Hendrik Baekeland invented Bakelite, the first fully synthetic plastic.
During World War II, the use of plastics increased dramatically as the demand for lightweight, durable materials for use in the battlefield grew. After the war, the use of plastics continued to rise as new types were developed and the range of products expanded.
In recent years, there has been increasing concern about the environmental impact of plastics. While their convenience and durability are advantageous, they come at a significant cost to the planet. Plastic pollution is a serious problem affecting our oceans, wildlife, and even human health.
Every year, millions of tons of plastic end up in our oceans, harming marine life and disrupting ecosystems. Plastic debris can suffocate or entangle marine animals, causing injury or death. Additionally, plastic breaks down into smaller particles known as microplastics, which are ingested by marine animals and can make their way up the food chain to end up on our plates. Some researchers suggest that by 2050, there could be more plastics than fish in the oceans by weight.
Besides its impact on marine life, plastic pollution also harms terrestrial animals and birds, who mistake plastic litter for food. Plastic waste creates a visual blight on our landscapes and communities and poses a public health hazard as toxic chemicals leach into soil and waterways. Large amounts of this waste end up in oceans, landfills, and other areas. Unfortunately, a staggering 91% of all plastics aren’t recycled, and almost all items ever produced are still around.
Sustainable alternatives to plastic
The best way to reduce plastic is to follow the 3 R´s:
- Reduce by cutting back on the amount of products we purchase
- Reuse by finding new ways to use items that otherwise would have been thrown out
- Recycle by sending existing products to industrial facilities to be converted into something new However proper sites may not be available everywhere. PET and HDPE are the most recycled
Use products not made with conventional plastics but with similar functionality, such as:
- Paper, ceramic, glass, metal, wood, and bamboo
- Natural fibers like sugarcane and wheat bagasse
- Bioplastics like PLA, PHA, and PBAT

The rise of Natural Fibers and Bioplastics
The scientific community has been experimenting with materials There are several types of bioplastics, each with their own unique properties. For example, starch-based bioplastics are strong and flexible, making them suitable for packaging materials and consumer goods. Cellulose-based bioplastics, on the other hand, are stiffer and more brittle, and are commonly used in the production of textiles. Bioplastics made from lactic acid are biodegradable and are used in medical applications and food packaging.
Bioplastics are often considered more sustainable because they are made from renewable resources and are biodegradable. Some break down much faster than traditional plastics. The best known are PLA and PBAT. A new group of biopolymers called PHA are produced by microorganisms such as bacteria.
The use of these bio-based polymers are not a definitive solution for plastic waste but are a step in the right direction, specially for single use products.
One of the main obstacles for widespread use of bioplastics is cost. They are more expensive to produce than conventional plastics, making them less appealing for companies and consumers. Another challenge is the lack of infrastructure for collecting and processing these materials, hence they may not be properly disposed off and end up in landfills anyway. Overall awareness and appropriate investments are the most immediate needs for an increased positive impact of these materials.
We promote zero consumption of unneeded items, however when necessary we offer eco friendly products with the following features:
Recyclable
Materials that instead of being discarded as waste, can be collected, processed, and transformed into new products. This process reduces the need for new raw materials, conserves natural resources, and minimizes the negative environmental impact. They must be feasible to collect, sort, process, and re-sell in the economic market.
Recycled
Materials derived from the processing of waste to create new products, thereby diverting them from landfills. These include both post-consumer waste (from households or businesses) and pre-consumer waste (from manufacturing processes), and their use conserves natural resources and reduces environmental impact.
Biodegradable
Materials that can be broken down, decomposed and returned to the environment by natural biological means, such as the action of microorganisms. They will eventually break down into natural elements, such as carbon dioxide and water, but the process can take a long time, may not happen in all environments, and may leave toxins or residues.
Compostable
Materials specifically designed to break down quickly and completely in a composting environment, where microorganisms transform them into nutrient-rich soil leaving little or no toxic residues (normally in 180 days if certified). These materials are typically made from renewable resources such as plant-based. There are industrial and home compost products.
Plastic Codes
The number printed on the bottom of plastic products is known as a “resin identification code,” and it is used to identify the type of plastic that the product is made from. The code is usually a number between 1 and 7, and it is often found printed in the product.
Each of them has specific recycling standards.
1: Polyethylene Terephthalate (PET or PETE)
2: High-Density Polyethylene (HDPE)
3: Polyvinyl Chloride (PVC)
4: Low-Density Polyethylene (LDPE)
5: Polypropylene (PP)
6: Polystyrene (PS)
7: Other Plastics (PLA)(ABS)
It is important to note that the number is not a guarantee of recyclability, and some local recycling programs may not accept certain types of plastic. It is best to check with your local authorities to determine which plastics are accepted.
Greenwashing is the practice of making false or misleading claims about the environmental benefits of a product or service. It is a form of marketing that is used to make a product or service appear more environmentally friendly than it actually is. Greenwashing can take many forms, such as exaggerating the environmental benefits of a product, making unverified claims, or using vague or undefined terms.
Examples of greenwashing can include products that are labeled as “organic” or “natural” when they do not meet the standards for those terms, products that use a small amount of recycled content but are still mostly made from virgin materials, or services that claim to be carbon neutral but do not offset their emissions in a meaningful way.
Greenwashing can be a problem because it can mislead consumers and make it difficult for them to make informed decisions about the products they purchase. Additionally, it can make it harder for truly environmentally friendly products and services to stand out and be recognized for their green credentials.
To avoid greenwashing, consumers can look for certifications and standards that verify the environmental claims of a product or service, and be wary of vague or undefined terms such as “green” or “eco-friendly”. They can also research the company and its practices to ensure that it truly is committed to sustainability.
