Farmers and livestock breeders who produce waste must be registered in the Balearic Islands' Waste Production and Management Registry to be able to treat it. Registration grants an Environmental Identification Number (NIMA) and costs 51 euros. Without this number, the company awarded the plastic collection contract cannot collect the manure, nor can it be delivered to TIRME (the Balearic Islands' waste management company). This requirement, imposed by the national waste law passed in 2022, means "more bureaucracy for farmers, with a giant trap," laments Joan Gaià, coordinator of Unió de Pagesos (Farmers' Union). However, he believes the initiative is good if all the collected plastic is recycled, because "if all this fuss is just to end up burning the plastic, it's just asking for trouble." In this regard, he points out that plastic is still currently used as fuel, so "companies have no incentive to recycle it." Furthermore, he refers to the difficulty some farmers are having registering. "They'll have to hire people to do it for them," he says. The cost of registration must be borne by everyone, although producers who generate less than 1,000 tons of non-hazardous waste per year will not have to pay the fee established by the state waste regulations.

The trend of personalized cups at festivals emerged with the intention of eliminating single-use plastics and reducing their environmental impact, but, according to the latest study by the Rezero Foundation, it has ended up becoming a new business model that contributes to pollution and environmental degradation.
