Mitsubishi Electric technologies have enabled the development of innovative composting machines that can turn food waste into high-quality fertiliser in just 24 hours. This solution responds to the global problem of waste, in particular food waste, which makes up about 30% of landfill waste*.
For Radisson Blu Scandinavia, this technology enables the daily processing of food waste from restaurants, room service, and other food-related operations. It is the end of the evening and hotel kitchen staff load bio-waste into a new machine. The next evening, staff will remove several kilograms of high-quality, nutrient rich fertiliser from the same machine. This is how the era of food waste ends.
What once took a year to complete can happens in under 24 hours, significantly improving efficiency and sustainability. This solution represents a major step forward in waste management and environmental protection.
“By transforming food waste into valuable fertiliser, Mitsubishi Electric, and bio solutions provider Solserv AB, are contributing to a more sustainable and circular economy, addressing both waste reduction and soil enrichment challenges” – explains Maria Wendt, Marketing Communication Manager at Mitsubishi Electric Scandinavia.
It is difficult to overstate the environmental benefits of composting technology from reducing collection to reducing methane emissions.
Food Waste Reduction
The composters can process large quantities of organic waste, from 30 kg to 1350 kg daily depending on the machine. This significantly reduces the volume of waste sent to landfill. Facilities for up to five hundred tonnes per day are also possible using the same technology. Moreover, they can process other types of organic waste, including biodegradable bags, expanding their potential for waste reduction.
One of the many environmental benefits is the reduced methane emissions. By diverting organic waste from landfills, these composters help reduce methane emissions, a major contributor to climate change. Landfill is the third largest source of methane emissions**, and composting helps mitigate this issue.
Soil Health Improvement
The resulting compost enriches the soil with nutrients and organic matter, promoting sustainable agriculture and reducing the need for chemical fertilisers. It also helps to conserve water by retaining moisture within the composting system, which is particularly beneficial in water-scarce regions.
Furthermore, the composters allow for continuous composting regardless of weather conditions, ensuring a consistent supply of compost throughout the year. Many models also have energy- saving features to minimise power consumption.
“Mitsubishi Electric’s expertise has been crucial in developing precise and efficient composting processes. This collaboration ensures consistent quality and performance across different scales of operation. The partnership between Mitsubishi Electric and Solserv aligns with the United Nations’ global goals, particularly in addressing the climate crisis. By converting organic waste into nutrient-rich compost efficiently, this technology promotes sustainability and significantly reduces waste” – sums up Patrik Johansson CEO at Solserv AB.
This innovative solution represents a major step forward in waste management and environmental protection. By transforming food waste into valuable fertiliser, Mitsubishi Electric and Solserv are contributing to a more sustainable and circular economy, addressing both waste reduction and soil enrichment challenges.
