  • Plastic Waste: Hidden Threat from Oceans to Norwegian Shores

    Plastic Waste: Hidden Threat from Oceans to Norwegian Shores

    Plastic pollution is a rising global crisis that spares no spot on our planet. From the deepest oceans to the pristine coastlines of Norway, traces of plastic waste are an unfortunate sight. This waste represents the intruder of a dangerous disgusting pollutant, yet it reflects a far-reaching systemic problem demanding global attention.

    Plastic pollution

    Scientists have been warning for years what out-of-control plastic pollution could do and have been cautioning that immediate steps be taken, while global plastic production and consumption levels saw a rise. The country of Norway, with its strict environmental stand, is proposing an international pact to decrease the flow of plastics into the environment. Yet, what is also important to point out is that even Norway adds to the plastic pollution.

    Thanks to the high-resolution study provided by Norwegian University of Science and Technology (NTNU) scientists and their colleagues with the help of the Norwegian Air Research Institute (NILU). We now have a complete, detailed mapping of the complex plastic cycle down to each type of product and polymer in Norway. But, being green, Norway discharges around 15,000 tons of plastic into the environment each year.

    The new study found that an enormous 758 thousand tons per year of plastic ends up on the Norwegian market, with 632 thousand tons as waste. Though nearly half this amount is burned, just 2.4% goes into the environment. Yet this “small” amount means an average of 2.8 kg per capita.

    The most significant contributors to macroplastics were considered to be consumer packaging, such as bottles and bags. On the other hand, one of the highest contributions to microplastics came from tire abrasion, especially from electric and hybrid cars. Production of such items continues to remain at high levels, although a focus remains on decreasing the amount that is released. We just consume more than we can gather. Thus, it is necessary to cut down on plastic use to stop the pollution at its roots.

  • How Better Refrigeration Can Reduce Global Food Waste?

    How Better Refrigeration Can Reduce Global Food Waste?

    A recent study by researchers at the University of Michigan has shed light on the significant potential of improved refrigeration to reduce global food waste. The study, published in the peer-reviewed journal; Environmental Research Letters, found that nearly half of the 1.3 billion tons of food wasted annually could be eliminated by fully refrigerated food supply chains worldwide.

    Impact of Food Waste

    Food waste is a pressing global issue, with approximately a third of the food produced globally each year going to waste. This staggering statistic is particularly concerning given that around 800 million people worldwide suffer from hunger. The environmental impact of food waste is also substantial, with food losses producing an estimated eight percent of human-caused greenhouse gas emissions.

    Role of Refrigeration

    The study highlights the crucial role that refrigeration plays in reducing food waste. By optimizing cold chains, food supply chains can significantly reduce the amount of food that goes to waste. This is particularly important in regions where food waste is a significant issue, such as Sub-Saharan Africa and South and Southeast Asia. These regions could see a reduction of 45% in food losses and a 54% decrease in associated emissions under optimized refrigeration conditions.

    Benefits of Improved Refrigeration

    The benefits of improved refrigeration extend beyond reducing food waste. Fully refrigerated supply chains could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally. This reduction in emissions is substantial and could have a significant impact on the environment.

    Importance of Localized Food Systems

    The study also emphasizes the importance of localized food systems in reducing food waste. In many situations, developing more localized, less industrialized “farm-to-table” food supply chains may yield food savings comparable to optimized cold chains. This approach not only reduces food waste but also promotes more sustainable and environmentally friendly food systems.

    Future of Food Waste Reduction

    The University of Michigan study provides a roadmap for reducing global food waste through improved refrigeration. The findings underscore the importance of optimizing cold chains and developing more localized food systems. As the world continues to grapple with the challenges of food waste, this study offers a beacon of hope for a more sustainable and environmentally conscious future.
