What type of insulation is marketed as eco-friendly and made from recycled plastic?

The type of insulation that is marketed as eco-friendly and made from recycled plastic is indeed plastic batts. This insulation product takes advantage of recycled materials, contributing to sustainability efforts by repurposing plastic waste that would otherwise be discarded. By using recycled plastic, this insulation presents a lower environmental impact compared to conventional materials.

Plastic batts can offer good thermal performance and serve as an alternative to traditional insulation types while appealing to environmentally conscious consumers. Their production process often emphasizes reducing waste and minimizing the carbon footprint associated with manufacturing new insulation materials. Moreover, these batts can help improve indoor air quality since they are less likely to off-gas harmful chemicals compared to some other forms of insulation.

The other types of insulation mentioned do not fit the description. Cotton batts, while they can be considered eco-friendly, are primarily made from natural cotton fibers rather than recycled plastic. Mineral wool batts are made from natural rocks and recycled slag, again not involving recycled plastic. Fiberglass batts, a widely used insulation type, are composed of glass fibers, which do not relate to recycled plastic. Thus, plastic batts stand out in this context as the correct answer due to their unique composition and eco-friendly marketing.
