There are eco-friendly options for ice block molds available in New Zealand. One option is to use silicone ice block molds, which are reusable and durable. Another option is to use stainless steel ice block molds, which are also reusable and can last for many years. Both of these options are eco-friendly as they eliminate the need for single-use plastic molds that end up in landfills. Additionally, some companies in New Zealand offer biodegradable and compostable ice block molds made from plant-based materials such as cornstarch or bamboo fiber. These eco-friendly options are a great way to reduce your environmental impact while still enjoying your favorite frozen treats.
