Embodiments provide methods for assembling an apparel product. The methods include applying a composition to a portion of a major component of the apparel product or a portion of a minor component of the apparel product. The methods include coupling the portion of the minor component with the portion of the major component via the composition. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with an adhesive. The major component and/or minor component includes a recyclable material. The methods include converting the composition to the adhesive. The adhesive includes a material having a cycloalkene bond.
