Why are scientists putting coffee into concrete?

Published

on

Scientists have devised a method to recycle used coffee grounds to improve the strength of  concrete.

Engineers at RMIT University have discovered a method to significantly enhance the strength of concrete by nearly 30% by incorporating processed coffee grounds into the construction material.

This approach involves transforming discarded coffee grounds into biochar, a lightweight residue reminiscent of charcoal. This biochar then replaces a portion of the sand that is typically an essential ingredient in concrete production.

The inspiration for this pioneering technique stemmed from a laudable motive – to combat coffee waste in workplaces, according to the research team behind the innovation.

In a noteworthy collaboration, the researchers are currently partnering with local councils to envisage upcoming infrastructure projects, including the construction of walkways and pavements, which will employ this revolutionary concrete.

One of the most promising environmental aspects of this method is its potential to diminish coffee waste ending up in landfills, in addition to easing the demand for natural sand, a vital resource extensively used in the construction industry.

The National Food Waste Strategy Feasibility Study reveals that around 3% of the country’s annual greenhouse emissions stem from food waste. With approximately 75,000 tonnes of coffee waste being generated annually, the newly developed technique could notably contribute to waste reduction efforts.

Termed as pyrolysis, the method involves subjecting coffee waste to temperatures of about 350°C. Remarkably, the engineering team has managed to make this technique more energy-efficient by conducting the process at lower temperatures than customary.

Through careful experimentation, the researchers ascertained that by substituting 15% of the sand conventionally employed in concrete production with coffee biochar, the resulting material exhibited a remarkable surge in strength – an impressive 29.3% increase.

In a heartfelt plea, Russian women have taken to the streets demanding the safe return of their loved ones from the Ukrainian front.

The conflict in Ukraine has stretched on for years, and the toll on families has been immense. Mothers, wives, sisters, and daughters are uniting to call for an end to the fighting and the return of their men.

The women, often referred to as the “mothers of the front,” are growing increasingly frustrated with the ongoing conflict. They argue that their husbands, sons, and brothers have been away for far too long, and the human cost of the war is simply too high.

With no clear resolution in sight, their calls for peace and reconciliation are becoming more urgent.

This grassroots movement has sparked a national conversation in Russia, with many questioning the government’s handling of the conflict.

While the official stance has been to support the separatist forces in Ukraine, these women are highlighting the personal tragedies and broken families left in the wake of the war. Their determination to bring their loved ones home is palpable.

The situation raises important questions about the impact of long-term conflicts on families, the role of women in peace movements, the government’s response to public sentiment, and the prospects for a peaceful resolution in the ongoing Ukraine conflict.

Workers reconsider roles due to lengthy travel times

A surge in resignations is hitting the job market as employees reevaluate the impact of long commutes on their work-life balance. The trend, intensified by the rise of remote work during the pandemic, sees a growing number of professionals opting to quit rather than endure extended travel times.

A recent survey conducted among commuters revealed that 68% of participants identified their daily journeys as a major source of stress. The findings suggest a paradigm shift in the traditional understanding of commuting as an inherent aspect of employment.

Employers are now grappling with the challenge of retaining talent as dissatisfaction with lengthy commutes becomes a catalyst for resignations. The implications extend beyond individual decisions, impacting productivity and overall workforce dynamics.

The phenomenon underscores the need for businesses to reassess their remote work policies and invest in solutions that alleviate the burden of commuting. As the job market adapts to evolving expectations, companies that fail to address the commute conundrum risk losing valuable contributors.
