Circular solution for E-commerce waste

Online shopping has become an integral part of our daily lives. With just a few taps on a smartphone, a wide range of items, from groceries to electronics, can be delivered right to our doorsteps — quickly, conveniently, and often at a lower cost than visiting a physical store. However, this convenience comes with a significant issue that many of us are aware of: the accumulation of cardboard boxes in the corner, the plastic mailers that we are uncertain how to recycle, and the products we send back because they did not fit or did not meet our expectations. All of this contributes to a substantial amount of waste, a large portion of which ultimately ends up in landfills.

A circular solution presents an alternative path forward. Rather than viewing packaging and products as single-use items, it promotes the idea of keeping materials in circulation for as long as possible. This involves creating packaging that can be reused, opting to repair items instead of discarding them, and discovering methods to give products a new lease on life. In essence, it moves us away from the conventional “take‑make‑dispose” model and towards a framework that minimizes waste, conserves resources, and benefits both individuals and the environment.

Wildfire to regrowth by circular means

When forests burn, the first images that come to mind are destruction, smoke, and loss. Yet wildfires are becoming more frequent and intense across the world, forcing us to rethink not only how we respond, but how we rebuild. Instead of treating the aftermath as waste to be cleared and forgotten, a circular approach asks a different question: what if the materials left behind could help restore the land itself? By reusing safe organic debris, rebuilding soil with compost and biochar, and supporting nature‑based recovery, communities can turn post‑fire landscapes into opportunities for regeneration. This shift — from a linear “clean up and throw away” mindset to a circular, restorative one — offers a path where recovery strengthens ecosystems rather than depleting them, and where renewal begins in the ashes.

Oil spills and circular solutions

For generations, oil has been used for many different reasons by human civilization, such as to generate electricity, heat homes, and have a stable economy. In recent times, every year, 90 million ballers of crude oil are transported to refineries for human use, showing its importance to our livelihoods. Oil has always been an essential component of our livelihood; however, the process of recovering raw oil from the Earth safely has not always been done properly. Due to human errors or technical issues, raw petroleum can be spilled in huge quantities on land or ocean and have an effect for a long time on the environment. This blog captures the reasons for oil spills, how they impact the environment, and circular solutions to mitigate the effects of oil spills.

How can the circular economy be practiced in slums

Slums, home to over 1 billion people worldwide, are the frontline of urban vulnerability. Overcrowding, poor sanitation, unsafe housing, and climate change converge to create daily risks of disease, displacement, and poverty. Open sewage contaminates water, fragile dwellings collapse under floods, and limited healthcare magnifies crises. Yet within these challenges lies opportunity: by inducting circular practices—such as waste-to-energy digesters, repurposed construction materials, and community recycling hubs—slums can transform hazards into resources. Circular solutions not only reduce illness and environmental damage but also generate livelihoods, strengthen resilience, and pave a way forward toward healthier, more sustainable urban futures.

Why Seaweed packaging works—where it’s missing

Plastic packaging is ubiquitous in everyday life, but the core problem driving the search for alternatives is not simply higher use — it is plastics’ persistence: their inability to decompose leads to accumulation in landfills, oceans, and soils. This long‑term stockpiling of nondegradable waste has triggered research into biodegradable materials. Seaweed‑based packaging emerged as a promising solution because seaweeds are abundant, renewable, and rich in polysaccharides that can form films and coatings. Seaweed packaging has been a huge success in the field of daily life packaging; however, it has yet to be introduced into industrial packaging. This is a significant concern, given that industrial plastic packaging causes substantial problems with carbon emissions worldwide.

How farm Nitrates pollute coastal waters? What we can do to stop it?

Farm nitrates can enter lakes and estuaries and cause pollution.

Nitrogen is a very important nutrient to help plants grow, as it is a major component in chlorophyll, which plants use to photosynthesise. Thus, nitrogen builds more yield for most plant species, compelling farmers to use it for better produce. The agricultural community uses fertilizers and manure, which carry huge amounts of different types of nitrates to increase plant yield, replenish soil nutrients, enhance soil stability, and much more. However, with nearly half of the world’s food production relying on fertilizers, it raises important questions about the impact of nitrates on coastal waters. Nitrates from farmed water commonly run off into lakes, estuaries, and groundwater, which affects overall coastal marine health. Let’s discover what issues arise due to this and what can be done to mitigate them.

Can the Jugaad system foster circular transportation?

The jugaad method stands out as a representation of resourcefulness, originality, and adaptation in the colorful tapestry of India’s creative landscape. Jugaad epitomizes the spirit of conservatism and inventiveness since it is based on the capacity to find unusual and frequently improvised solutions to common issues. The jugaad system has, however, expanded beyond its humble beginnings into a number of fields, including transportation. About 64% of the world’s oil consumption, 27% of all energy use, and 23% of the carbon dioxide emissions related to energy are accounted for by the transportation sector. Urban passenger and freight transit use 5% of the global energy supply in areas with dense urban populations. Given that it is predicted that by 2050, 68% of people in the world would live in urban areas, this situation could get even worse.

This article examines the relationship between the jugaad ethos and the urgent need for circular practices in transit and how they can be effectively combined to attain circularity in the industry. The article also explores how jugaad-inspired inventions could promote circular transportation solutions that are resource-efficient, long-lasting, and revolutionary for the future of mobility.

How can consumer awareness foster circular economy adoption?

The circular economic model aims to produce goods and services sustainably through limited consumption and waste management at all stages of a product’s lifecycle. In contrast to the linear economy, the circular economic model aims to break the produce-consume-dispose pattern by recycling the waste generated during these stages. This is then transformed into raw materials to be used for production and other purposes. However, only 7.2% of the world’s total economy is circular. This is largely due to increased material consumption. This has reduced the global circularity from 9.1% in 2018 to 8.6% in 2020 to 7.2% in 2023. This circularity gap draws attention to the reality that the world exclusively uses virgin resources, of which 90% are wasted, lost, or otherwise unusable since they are consumed by permanent stock.

What is the science behind Miyawaki forests?

Trees play a pivotal role in maintaining the health of the ecosystem, although, it seems like humans are ignorant of this fact. Trees have been mercilessly cut down in the name of ‘development’ which has repercussions like soil erosion, lowering of the water table, silting, desertification. This has led to deeper implications including food crises, water shortages, health crises, loss of livelihood, and climate change. Afforestation could help to reverse this damage. But are planting trees enough? Is all the green really ‘green’? While planting trees is a great practice, not all trees will give the same advantages. Some end up being ornamental pieces that don’t support local biodiversity. Some introduced foreign species tend to dominate and threaten the existence of native species. There is a solution to provide a shade of greenery that serves its purpose well. It is gaining much popularity and is called the Miyawaki forest method.

Can shipping containers help circular economy?

The shipping containers carry shipments all across the globe. They have been useful tools for manufacturing companies. A shipping container is considered an “intermodal freight container“, i.e., it can be moved from one mode of transport to another- it can be loaded on ships, on trains, and on trucks thereby allowing goods transport via water, rail and road. They are sturdy, reusable and can carry about 27,600 kg. They can serve for a life span of 15-20 years, although the average container will spend more than half its life sitting empty and unused. They often don’t return to their place of origin as it gets expensive to send them back. They end up piling up on ports or even construction sites. This is another example of the malfunction of international capitalism. They can be melted down but that requires over 8000kWh energy for each container! So, mostly they end up getting rusted or are left in landfills.

Can agroforestry regenerate farm land?

Agroforestry integrates agriculture and forestry, with a focus on using a variety of plant species to help one another. The system uses woody perennials as a support for growing herbaceous plants and it can be implemented from the scale of a home garden to a large estate. Woody perennials are evergreen trees that have hard stems and grow continuously with each passing year, surviving even through winters. Herbaceous plants, on the other hand, have soft stems and a periodic life cycle. In general, these are the plants we cultivate for our consumption. In effect, the system of agroforestry utilizes the circular process of the natural ecosystem, rather than breaking the flow of the biosphere through monocropping.

What is E-Waste recycling and its importance?

The rapid global rise in technology has generated advanced electrical and electronic equipment with short lifespans. For example, in 2018, Apple sold more than 217 million iPhones. A consequence of such high demand and supply of electronic products is electronic waste (e-waste) which, in 2018 amounted to 50 million tonnes. E-waste is projected to grow annually 3-5% which is three times more than other waste streams. Reports on recycling rates vary, with estimates of around 20–30%. It is estimated that more than 70% of globally produced waste electronics and electrical equipment (WEEE) enter China, Africa and India for reprocessing, much of it illegally, and often using crude, hazardous and inefficient processes. Dumping and incinerating large amounts of WEEE has a severe impact on human life and the environment, as it leads to the release of toxic heavy elements such as lead, mercury, chromium, nickel, beryllium, arsenic and antimony into the air, soil and water cycles.

Why Upcycled Products Cost More?

Waste has become a major environmental challenge in cities as the population increases and people consume more goods. It is estimated that the European Union (EU) alone generates 2.5 billion tonnes of waste every year. In our linear economies, such waste generation is common in every sector. In the fashion industry, for example, the equivalent of one garbage truck of textiles ends up in the landfill or gets incinerated. However, people are coming up with innovation and initiatives to tackle these problems and propose ways of avoiding the accumulation of waste. One such concept is called “upcycling”. “Upcycling is the reuse of otherwise discarded objects or materials in such a way as to create a product of higher quality or value than the original”. The product created can have more artistic or environmental value. The main motive of upcycling is to continue the life of the product.

What is Circular Economy?

In 1684, the steam engine was invented by Thomas Savery which has arguably kick-started the industrial revolution. Since then, human civilization has produced large amounts of goods. Humans have invented fast fashion, industrialized agriculture, processed foods and other forms of mass-produced goods. Despite the job generation, improvement in human life and technological advancements that have come along with the industrial revolution, we have also generated tremendous amounts of waste. Wrapping our heads around the enormous amount of food and goods that are thrown away every year is not an easy task. For example, every second, the equivalent of one garbage truck of textiles ends up in the landfill or gets incinerated. This amounts to upwards of 31.5 billion garbage trucks of textiles every year. It is estimated that every year, 2.5 billion tonnes of waste is generated in the EU. These issues have been caused due to the linear nature of our economies. Manufacturers use raw materials and make products which are non-recyclable and perish easily. They do not consider what happens when the products reach the end their life and therefore, the products are thrown in landfills.

Similar efforts are being made in London, where the Mayor has committed for London to be a zero carbon city by 2050. The International Energy Agency (IEA) has also forecasted that solar energy will be the main driver of growth in global electricity over the next decade with the onshore and offshore wind taking second and third place, respectively. All of these are good news but since solar and wind power are relatively young technologies, there exists a real concern of waste- often overlooked. What happens when the renewable energy generators reach the end of their lifetime and is there a way to recycle solar photo-voltaic (PV) modules and wind turbines?

How to attain circular economy in fashion industry?

The fashion industry is the second most polluting industry (after the oil industry). This is due to the high water footprint, land footprint, high use of fertilizers and pesticides. The industry is also responsible for 10% of the global greenhouse gas emissions worldwide due to its long supply chains and energy-intensive production. As the population grew consumerism has created a mass market for cheap apparel where products are perceived and treated as disposable. This has given birth to the notion of ‘fast fashion’, which represents low-quality products that are mass-produced for easy consumption. A staggering 80 billion pieces of clothing are consumed each year which represents an increase of 400% from the 1990s.
