Zero-waste model

Introduction: Starting a sustainable business is the new cool in the startup world. Companies like Loop, Rothy’s, and Package Free Shop have built successful businesses that promote a zero-waste model. Sharing economy model, circular economy model, and the triple-bottom-line model are other sustainable business models contributing to the economy in their respective ways.

Zero-waste model: Zero-waste businesses aim to reduce waste by either eliminating it altogether or by promoting responsible disposal. One such company is Loop, which is like the modern-day milkman service. Loop delivers groceries in reusable containers to your doorstep and picks up the empties. Brands like Rothy’s use materials made from recycled plastic, while Package Free Shop has a selection of zero-waste alternatives to everyday products.

In a world where all we hear is “throw away, throw away,” zero waste is a breath of fresh air. Not only is it environmentally responsible, but it also introduces a sense of responsibility in the consumers by making them conscious of their lifestyle choices.

So, the next time you are looking for a pair of trendy, eco-friendly shoes, check out Rothy’s. Or if you are interested in sustainable living, visit the Package Free Shop. Zero-waste businesses are not just eco-friendly but also trendy and convenient.

Sharing economy model


Sustainable business models have gained significant attention in recent years and for good reason. With the constant threat of climate change and depleting natural resources, it is essential to adopt a sustainable approach to business. Startups have taken the lead in adopting sustainable models, and we take a look at some inspiring examples in this blog.

Sharing Economy Model:

With the aim of creating a more resourceful and sustainable world, the sharing economy model is based on individuals sharing their resources with others. This model has found a footing in sectors such as transportation, hospitality and goods exchange.

Zipcar is a popular car-sharing service that allows members to rent cars for short periods, reducing the need for car ownership and the resulting environmental impact. Airbnb, on the other hand, offers a platform for people to rent out their homes or spare rooms to travellers, providing a more authentic travel experience and reducing the need for new hotel constructions. Freecycle, a non-profit organisation, enables people to give away items they no longer need to others who can make use of them, contributing to reduced waste and landfill.

These sharing economy models provide an alternative to traditional business models and have a significant impact on the community and environment. They have also proven to be economically beneficial.

As we have seen, startups have taken the lead in adopting and implementing sustainable business models. These models not only make business sense but also contribute to a better world. By supporting these businesses, we can all play a part in building a brighter, more sustainable future.

Circular economy model

The circular economy model is all about creating a closed-loop system wherein waste is minimized and resources are maximized. Ecoalf is a company that is breaking new grounds in this arena by creating fashion wear that is entirely made out of recycled materials. From plastic bottles to fishing nets, Ecoalf is creating a range of products that are both stylish and eco-friendly.

The Renewal Workshop is a company that works with apparel brands to extend the life cycle of their products. By repairing, upcycling, and reselling products, The Renewal Workshop is making sure that clothes stay in use for a longer time, thereby reducing their carbon footprint. They also ensure that any leftover fabric or trim scraps are reused or recycled, resulting in zero-waste production.

Foodloop is a company that is working towards reducing food waste by providing an innovative solution to grocery stores. They buy food that is about to expire at a discounted price and sell it at a lower price, thus preventing it from going to waste. They have also partnered with non-profit organizations to donate leftover food to those in need.

These companies are leading the way in the circular economy model by showing that sustainability and profits are not mutually exclusive. By adopting this model, they are not just reducing their environmental impact but also creating a more ethical and responsible business model. And with the current generation being more conscious about the environment than ever, it’s safe to say that the circular economy model is here to stay.

Triple-bottom-line model

When it comes to sustainability and ethical business practices, Patagonia, Allbirds, and Pela are front runners. These companies have incorporated a triple-bottom-line model into their operations, which focuses on environmental sustainability, social responsibility, and financial performance.

Patagonia, known for its outdoor clothing and gear, has been a leader in promoting sustainable business practices for decades. The company’s mission statement is “Build the best product, cause no unnecessary harm, use business to inspire and implement solutions to the environmental crisis.” Patagonia prioritizes the use of sustainable materials like organic cotton, recycled polyester, and hemp in its products. The company also takes responsibility for the environmental impact of its operations, invests in renewable energy, and donates 1% of its sales to environmental causes.

Allbirds, a shoe company known for its comfortable, sustainable, and stylish products, has a similar triple-bottom-line approach. Allbirds uses eco-friendly materials like eucalyptus fibers, recycled bottles, and natural rubber to make its shoes. The company also prioritizes the welfare of its workers, ensuring fair wages and safe working conditions. Allbirds also focuses on giving back to the planet, investing in regenerative practices to offset its carbon footprint.

Pela, a phone case company, is another excellent example of a triple-bottom-line model business. Pela uses sustainable materials like flax, cassava starch, and bamboo in its products, which are 100% compostable and biodegradable. The company also donates a portion of its profits to organizations working to reduce plastic waste in the ocean.

Incorporating a triple-bottom-line model into business operations can have a significant impact on the planet and society. Patagonia, Allbirds, and Pela are just a few examples of companies that are leading the way in sustainable and ethical business practices. Their success is proof that a triple-bottom-line approach is not only beneficial for the planet and society but also for the financial bottom line.

B-Corp certification

B-Corp certification is a designation offered by B Lab to companies that meet rigorous social and environmental standards. To become certified, a company must undergo a comprehensive assessment that evaluates its impact on workers, customers, community, and the environment. The certification process is not easy, and not every company that applies is approved.

Why does B-Corp certification matter? For one, it provides a stamp of approval for companies that prioritize more than just profits. B-Corp certification is like a Good Housekeeping seal of approval for businesses that care about social and environmental impact. It also helps consumers identify companies that align with their values, and it can be a useful tool for investors who want to put their money behind businesses that are better for the planet.

Many B-Corp certified companies are making a real difference in the world. Take Patagonia, for example. The outdoor gear company has been a leader in sustainable business practices for years, and it was one of the first companies to become B-Corp certified. Patagonia’s focus on environmental responsibility has led to innovations like using recycled materials in its products and funding grassroots campaigns to protect wild places.

Allbirds, another B-Corp certified company, has set a goal of achieving carbon neutrality by 2025. The sustainable footwear company also uses natural materials like wool and eucalyptus in its products.

Pela, a B-Corp certified company that makes eco-friendly phone cases, uses 100% compostable materials in its products and partners with organizations to clean up plastic waste from oceans.

In conclusion, B-Corp certification is an important designation for companies that want to do more than just make money. It demonstrates a commitment to social and environmental responsibility, and it can help consumers identify brands that align with their values. The companies that have achieved B-Corp certification are making a real difference in the world and setting an example for others to follow.


As we look towards the future, it’s clear that sustainable business models are here to stay. Companies across various industries have already embraced them and are setting a precedent for others to follow. The movement towards sustainable practices is not just an ethical choice, but also a smart business move. The key to success for businesses in the future will be to integrate sustainability into every aspect of their operations.

But it’s not just up to businesses to lead this charge. Consumers also have a role to play in supporting sustainable businesses. By making informed choices and supporting companies that prioritize sustainability, we can use our purchasing power to drive change. It’s not just about what we buy, but also how we dispose of it. Every little step we take towards reducing waste and supporting sustainable practices can have a significant impact.

So let’s make a commitment to support the companies that are leading the way towards a more sustainable future. Whether it’s choosing a zero-waste brand like Rothy’s or supporting a B-Corp certified company like Patagonia, every action counts. Through our collective efforts, we can create a better world not just for ourselves, but for future generations.
