Finland advises against biomaterial waste bags due to processing complications

A recent report by Yle highlighted issues associated with the increasing use of biomaterial waste bags in Finland. These biodegradable bags can create complications for facilities that process organic waste, as they often degrade into a stretchy sludge during biogas production, potentially clogging equipment. In severe cases, this has necessitated halting operations for cleaning. Consequently, consumers have been advised to consider alternative options, such as using paper bags for organic waste. It is generally not recommended to dispose of waste directly in biowaste containers without a bag.

Tiila Korhonen, operations manager for the Helsinki Region Environmental Services Authority (HSY), which oversees waste processing for over a million people, recommends that individuals consult their local waste management guidelines. She emphasizes that paper waste bags are typically a better choice than biomaterial ones, being more environmentally friendly and effective at absorbing moisture.

Consumers are encouraged to utilize existing paper waste at home, such as old cereal, flour, or candy bags, as well as shopping bags that are free of plastic. To prevent thinner paper bags from breaking when wet, Korhonen suggests placing cardboard egg cartons at the bottom for absorption.

There have been claims that regular plastic bags might be preferable for organic waste management, as they are easier to separate from clogs than biomaterial bags. However, Korhonen refutes this, asserting that plastic bags should not be used for organic waste collection due to concerns regarding microplastic contamination in the environment.

Finally, she underscores the importance of waste sorting, clarifying that different types of waste are indeed processed separately, despite appearances during collection.
