The water-energy-food nexus faces many challenges that negatively impact the farmers growing our food – not enough water, potential effects of climate change, difficulty connecting to markets, inaccessible renewable energy technologies, and a lack of agricultural knowledge, to name a few. However, with all these challenges come opportunities for businesses, non-profits, and academic/research organizations to step in, leverage their innovative solutions, and help improve the agricultural sector’s sustainability while helping farmers grow more food with less water and energy. One of the ways in which these innovations have been able to scale and create impact, is through the Water and Energy for Food Grand Challenge.
Since 2020, the Water and Energy for Food (WE4F) Grand Challenge has worked with innovators through five Regional Innovation Hubs covering East Africa, Middle East and North Africa, South and Southeast Asia, Southern and Central Africa and West Africa. These hubs have provided more than 135 innovators with grants, technical assistance, investment facilitation, and enabling environment support. Through this support, innovators scaled their nexus solutions, impacting 3.6 million end-users and helping them grow 6.8 million tons of food, save 1.2 billion kilowatt-hours of energy, reduce water consumption by 10.8 billion liters, and prevent 1.5 million tons of CO2e. 
As the program draws to a close over the next year, there are many lessons learned and recommendations to be shared with the broader community. To begin learning about WE4F’s experiences, the program cordially invites you to attend a webinar scheduled for June 18th at 9am ET. 
Entitled “Water and Energy for Food Grand Challenge – Final Evaluation Webinar”, and hosted by Dexis Consulting Group, this webinar will present findings on USAID-implemented activities in the Middle East and North Africa, South and Southeast Asia, and Southern and Central Africa.

The Most Promising Fabric Innovations in Sustainability in 2024

The Most Promising Fabric Innovations in Sustainability in 2024

In 2024, what are the fabric innovations to look out for, and where are the names we know at right now? Read on to find out. The new materials landscape in 2024 Sustainable fashion is constantly evolving as experts work to create more responsible materials and alternatives to the conventional fabrics that are negatively impacting […]

Extra-strong concrete — with coffee

Extra-strong concrete — with coffee

RMIT University has come up with a novel use for spent coffee grounds — as a valuable component in concrete.

The university is currently collaborating with Macedon Ranges Shire Council on a coffee concrete footpath trial in Gisborne.

RMIT has several other projects planned across Victoria in which coffee grounds will be turned into biochar and transformed into a resource for the construction industry. The RMIT team will partner with Australian-owned BildGroup — a civil infrastructure, asphalt paving and road profiling company — to deliver these circular-economy projects.

Australia generates 75 million kilograms of ground coffee waste every year. Most of this waste currently goes to landfill, but it has the potential to replace up to 655m kg of sand in concrete because spent coffee is a denser material. Globally, 10bn kg of spent coffee is generated annually, which could replace up to 90bn kg of sand in concrete.

While organic waste like coffee grounds cannot be added directly to concrete because it would decompose over time and weaken the building material, the RMIT team has developed a technique to make a suitable coffee biochar via a low-energy process without oxygen at 350°C. The resulting mixture makes the concrete 30% stronger, the researchers said.

The team is using a similar technique to turn other organic waste, including wood chips, into biochar that can also be used to make stronger concrete. Both types of biochar are being tested in the Macedon Ranges footpath trial.

“It’s very exciting to see this world-first trial of our coffee and wood-based biochar in these footpaths collaboration with Macedon Ranges Shire Council,” said Dr Rajeev Roychand, from RMIT’s School of Engineering.

“Sand is getting scarce over time, and this waste can replace up to 15% of the sand in concrete.”

Shane Walden, Council’s Director of Assets and Operations, said it was important for the council to be involved in projects such as this and to be working closely with universities like RMIT.

“This not only helps improve the knowledge level of our contractors and our staff, but it also has lots of other benefits and benefits that are important to our community,” he said.

“This includes helping the environment, acting sustainably and, most importantly, reducing waste to landfill and having a circular economy.”

Walden said that despite the fact that the new concrete contains coffee grounds or mulch, residents aren’t really going to see or smell any difference.

Turning coffee concrete into a commercial reality

If the trial concrete footpaths in Gisborne perform well, the RMIT team is aiming for the commercial rollout of its innovation.

“We are currently working in the supply chain sector so that we can make this research into a mainstream product for commercial applications, and we’re not only looking into coffee ­— we’re expanding this into all forms of different organic waste,” Roychand said.

“Every biochar produced from a different organic material comes with varying composition, in addition to the difference in carbon content, particle size and absorbency, that can boost the performance of concrete in a range of ways.”

If this RMIT innovation can be integrated into the supply chain, it might bring cost savings for construction companies and concreters by reducing the amount of cement needed.

“Since we are achieving a 30% increase in strength for the coffee concrete, this could reduce the required cement content by as much as 10%, based on our previous experience,” Roychand said.

The trial with Macedon Ranges Shire Council did not reduce the amount of cement normally used to make concrete for footpath projects, but the RMIT team plans to experiment with using less cement in future.

‘Transforming spent coffee grounds into a valuable resource for the enhancement of concrete strength’ has been published in the Journal of Cleaner Production.
