Accelerator is a traditional resin that has a degradation enabling additive, which degrades the hydrocarbon chains of the resin through hydrolysis, causing a majority of the mass of the product to be released in the form of gasses, which is desirable for methane re-capturing landfills. Accelerator’s additive does not produce microplastics. Please note the definition of microplastic is a plastic particle smaller than 5mm that is not biodegradable.
