Summary

Amsterdam is striving to become a circular economy by 2050, aiming to reduce raw material consumption, cut waste, and recycle more to lower emissions. The city innovates with solutions like the *Grade* startup's system to collect waterborne plastic waste, achieving an 86% collection success rate. Researchers have developed eco-friendly materials, including an adhesive made from waste, which could replace traditional adhesives and materials like aluminum. With a focus on sustainability, Amsterdam plans to replace harmful materials with eco-friendly alternatives, establishing itself as a pioneer in circular economies.

Takeaways

• 😀 Amsterdam is striving to achieve a circular economy by 2050, focusing on reducing raw material usage, waste, and emissions.
• 😀 The city collects 42 tons of plastic waste annually from its canals, and the volume of waste is believed to be even higher.
• 😀 Two-thirds of ocean plastic waste is carried by rivers, which is why preventing waste from entering waterways is a key priority.
• 😀 A startup company, Grade, has developed an innovative pipe system that helps collect floating waste from waterways by using bubbles to push it toward the shore.
• 😀 The system has proven successful in trials, collecting up to 86% of floating waste in the water.
• 😀 Dutch scientists have developed a water purification system that produces a bonding material called 'Kaum Merah,' which has various applications in manufacturing and construction.
• 😀 The goal is to recycle waste and produce higher-value materials, improving the circular economy and reducing environmental impact.
• 😀 'Kaum Merah' is a sustainable adhesive material that could replace petroleum-based adhesives used in the industry, benefiting both the environment and economy.
• 😀 A product of water purification installations, 'Kaum Merah' could produce up to 800 tons annually, helping reduce waste and generate value.
• 😀 Researchers are exploring ways to combine 'Kaum Merah' with recycled materials like toilet paper and peach pits, creating new products like road signs and construction materials, aiming to use 80% organic materials.
• 😀 Amsterdam aims to replace tropical wood with materials made from recycled waste, and in the next 10 years, it plans to replace aluminum with composite materials to reduce CO2 emissions.

Q & A

What is Amsterdam's goal for 2050?

Amsterdam aims to achieve a circular economy by 2050, which includes reducing raw material usage, minimizing waste, and maximizing recycling.

How does Amsterdam tackle the problem of plastic waste in the city's canals?

Amsterdam's cleaning department collects 42 tons of plastic waste that floats in the city's canals every year. The volume of plastic waste may actually be higher.

What is the connection between plastic pollution in the streets and its impact on rivers and oceans?

Most of the plastic waste seen on the streets eventually ends up in rivers, which then transport it to the ocean. Rivers act as a transportation mechanism for plastic pollution.

How does the technology behind the 'grade' startup help collect waste from water?

The 'grade' startup uses a pipe placed across waterways, with holes that pump water out. Bubbles generated by the system push waste to the surface, where it is directed to the shore and collected in containers.

What percentage of water waste can the 'grade' system collect on average?

The system has shown that it can collect an average of 86% of the waste in the water during trials.

What is 'Kaum Merah', and how is it produced?

'Kaum Merah' is an adhesive material created from purified wastewater, which has various applications in manufacturing and construction industries.

What is the significance of 'Kaum Merah' in the circular economy?

'Kaum Merah' plays a crucial role in circular systems by turning waste into high-value materials that can be used across industries, reducing the environmental impact of conventional adhesives made from oil-based materials.

What is the potential market for materials made from 'Kaum Merah'?

'Kaum Merah' can be used widely as an adhesive in various industries, such as construction, and has the potential to replace more harmful materials in manufacturing.

How does the circular economy approach in Amsterdam relate to recycling and waste management?

The circular economy in Amsterdam focuses on optimizing waste management, ensuring that products are reused, recycled, or repurposed, ultimately creating higher-value products from waste materials.

What challenges are associated with replacing materials like aluminum in the circular economy?

One challenge is the high cost of alternative materials like 'Kaum Merah' composites. Efforts are underway to reduce the cost of these materials to make them more competitive and viable alternatives to aluminum, which has a significant CO2 footprint.
