English to Spanish Marketing Materials (Plastics, Ceramics, etc.) Recycling

Contexto:

"There are essentially three generic types of PET bales that are purchased in the PET recycling
industry. These are: 1) bales consisting solely of PET carbonated beverage bottles -- referred to
throughout the industry as “soda bales”; 2) those that consist of a mixture of soda bottles and
“custom” PET containers and referred to in the industry as ****“curbside bales”****; and, 3) bales
composed solely of custom-PET bottles -- referred to as “custom bales.” The increase of
curbside recycling programs around the United States has made curbside bales the most prevalent
form of PET offered for sale. (In cases where curbside bales are offered for sale, it is imperative
to confirm with a particular purchaser if they have restrictions on the percentage of custom-PET
containers that they allow relative to PET carbonated beverage containers.)"
