🔄 Plastic life cycle
In 2021, 391 million tons of plastics were produced globally. Production has grown enormously: from 1950 to 2015, 7.8 billion tons were produced cumulatively — more than one ton per person alive. Half of it was produced in the last 13 years. China is the largest producer with 32% of the global total. Argentina produces around 1.6 million tons of plastic per year. If we continue at this level of production, by 2050 there will be more plastic than fish in the oceans. (Plastics Europe 2022 · Geyer et al. 2017 · Argentina's Ministry of Finance, 2019 · World Economic Forum, 2016)
Each person uses around 45 kg of plastic per year globally. In North America and the EU, more than 100 kg per person. In Argentina: between 40 and 42 kg per capita. A million plastic bottles are bought every minute worldwide. An estimated 4 to 5 trillion plastic bags are produced every year. (Plastics Insight 2015 · Wang et al. 2019 · Argentina's Ministry of Finance 2019 · The Guardian 2017)
Plastics don't disappear. They can take more than 500 years to break into smaller pieces. Plastic never biodegrades — it isn't broken down by bacteria or fungi, so nature doesn't assimilate it. The process is slower in the oceans than on land. This means it accumulates at an accelerating pace with devastating consequences. (Greenpeace, 2016)
🌊 Oceans
The oceans cover 3/4 of the Earth's surface and hold 97% of its water. They are the most diverse and important ecosystem: more than 3 billion people depend on them for their livelihoods. They produce more than 50% of the world's oxygen, store 50 times more CO₂ than the atmosphere, regulate the global climate and are a source of food for billions of people. Yet 40% of the oceans are already affected by pollution. (UNDP 2022 · NOAA 2022 · UN 2022)
171 trillion microplastics float in the ocean, weighing 2.3 million tons — the equivalent of more than 12,770 blue whales. Plastics account for between 60 and 80% of marine debris. 70% of the marine litter that enters ends up on the seabed, 15% on beaches and 15% floats on the surface. At least 5 "plastic islands" have been discovered. The one in the North Pacific has at least 79,000 tons floating over 1.6 million km². A plastic bag was found in the Mariana Trench at a depth of 10,898 meters. (Eriksen et al. 2023 · Lebreton et al. 2018 · Chiba et al. 2018)
Approximately 11 million tons of plastic end up in the oceans every year — one full garbage truck per minute. 80% of the plastic in the oceans comes from land-based activities. Rivers carry between 1.15 and 2.41 million tons of plastic to the sea every year. More than 1,000 rivers are responsible for 80% of that pollution. (Jambeck et al. 2015 · Lebreton et al. 2017 · Meijer et al. 2021 · Li et al. 2016)
⚠️ Problem
They are plastic fragments of 5 mm or less. Plastic breaks apart through light, heat, abrasion and moisture, but never disappears. Once in the sea it is practically impossible to remove them. Microplastics are eaten by marine animals, entering our food chain. They also absorb and concentrate toxins present in the water — including heavy metals. Plastics also contain chemical additives that are released as they degrade. (UNEP 2018 · Rochman et al. 2014 · Barboza et al. 2018 · GESAMP 2015)
The problem is not the material but its use and abuse. Plastic is popular for being cheap, practical and versatile, but it is a non-biodegradable polymer. Seven of the ten most abundant items on beaches are single-use plastics. If production continues on the current trend, 12 billion tons of plastic waste are expected to end up in landfills or in the environment by 2050. (Roman et al. 2020 · Geyer et al. 2017)
Yes. We ingest approximately 5 grams of plastic per week — the equivalent of a credit card. Microplastics have been found in fish, mollusks, table salt, and recently in blood and breast milk. Microplastics accumulate in animal tissues (bioaccumulation) and can move from prey to predator (biomagnification). (World Economic Forum 2019 · Yang et al. 2015 · Leslie et al. 2022 · Ragusa et al. 2022)
Approximately 700 marine species have been affected by plastic pollution (entanglement, suffocation, poisoning). In 20 years the number of affected species doubled. Plastics cause serious injuries, mutilation, suffocation, and reproductive and immune damage. More than 80% of seabird nests contain plastic fibers. In Argentina, plastic has been found in franciscana dolphins, sea lions, turtles, fish and invertebrates consumed by humans. (Gall and Thompson 2015 · Kühn et al. 2015 · Denuncio et al. 2011 · 2017)
Argentina produces around 1.7 million tons of plastic per year, 45% of it for disposable packaging. Annual consumption is 42 kg per capita. More than 2.7 million tons of plastic waste are generated. Argentina is among the 25 countries that produce the most plastic waste. Only 6% of municipal solid waste is recycled. 71% goes to sanitary landfills and 23% to open-air dumps. In 2024, plastic accounted for 74% of the waste on Buenos Aires province beaches. (Argentina's Ministry of Finance 2019 · UN Environment 2018 · Vida Silvestre 2022)
The evidence suggests it is. We are exposed to plastic throughout our whole lives: through ingestion (food, salt, water), inhalation (airborne fibers, household dust) and contact with additives such as BPA. Microplastics have been detected in blood, breast milk, lungs and brain. People with dementia have up to 10 times more microplastics in the brain. People with arteries contaminated with microplastics have a 5 times higher risk of stroke or heart attack. BPA mimics estrogen and can disrupt the reproductive system. Burning plastic releases highly harmful toxins. (Leslie et al. 2022 · Nature Medicine 2024 · NEJM 2024 · Cox et al. 2019)
➡️ Solutions
It is an economic model that seeks to decouple economic activity from the consumption of finite resources and eliminate waste from the system by design. Unlike the linear economy (take → make → dispose), the circular economy aims for waste to become resources that re-enter the production system. Its principles: preserve natural capital, optimize resources and foster system effectiveness. To achieve this, plastics must be fully reusable, recyclable or compostable in a commercially viable way. (Ellen MacArthur Foundation, 2022)
No, it isn't. Recycling doesn't prevent the final disposal of plastics, it only delays it. Of all the plastic produced from 1950 to 2015, 79% ended up in landfills or dumps, 12% was incinerated and only 9% was recycled. Plastics can only be recycled 2 or 3 times (they lose quality with each cycle). Recycling is technically difficult — not all types of plastic can be processed together — and economically unattractive. The only way to reduce the amount of material ending up in landfills is to produce less from the start. (Geyer et al. 2017 · National Geography 2018 · Zink and Geyer 2018)
Not necessarily. The definition of "bioplastic" is so broad that it is confusing. You have to distinguish the origin of the material (bio-based) from how it must be disposed of (biodegradable/compostable). Key problem: if a bioplastic is not disposed of correctly, its degradation can be as inefficient as that of a conventional plastic. Biodegradable bags exposed to real conditions (sea, soil, air) did not deteriorate significantly. Without the right infrastructure and proper certifications, bioplastic ends up being as problematic as conventional plastic. (European Bioplastics · Napper and Thompson 2019 · UNEP 2015)
We believe the best solution is to REDUCE the use of disposable plastics as much as possible. We need to recycle and move toward a circular economy, but that doesn't solve the underlying problem. Reuse delays disposal but plastics keep accumulating. The key is to avoid and prevent plastic from the design stage: ask yourself which plastics you can eliminate right away and set up a plan to reduce demand.
