How Latin America wastes billions of dollars worth of valuable metals
Mining News Pro - Latin America has a big opportunity to recover valuable materials from e-waste but has been throwing it into the garbage, according to a new report produced by the Sustainable Cycles Programme, co-hosted by the UN University and the UN Institute for Training and Research.

Data compiled for the report show that the e-waste generated regionally in 2019 contained 7000 kilos of gold, 310 kilos of rare-earth metals, 591 million kilos of iron, 54 million kilos of copper, and 91 million kilos of aluminum, representing a total value of roughly $1.7 billion of secondary raw materials.

The dossier also shows that electronic waste in 13 Latin American countries rose by 49% between 2010 and 2019, roughly the world average. The issue is that just 3% was collected and safely managed, a fraction of the 17.4% global average.

In fact, out of the 13 participating countries, only Bolivia, Chile, Costa Rica, Ecuador, and Peru have instituted specific legislation for e-waste and Extended Producer Responsibility (EPR) systems focusing on e-waste regulation. The rest of the countries have some legal and regulatory frameworks for general waste management.

Some figures
In 2019, e-waste generated by 206 million citizens in the 13 countries under scrutiny reached 1,300,000 tons —equal in weight to a 670 kilometers line of fully-loaded 40-ton trucks. The comparable figure in 2010 was 900,000 tons, generated by about 185 million citizens.

The study found that one-third of the region’s e-waste consists of small equipment such as microwaves, grills and toasters, speakers, cameras. The next largest categories are large equipment such as dishwashers, washing machines, ovens, and central heating systems, as well as temperature exchange equipment like fridges, freezers, air conditioners, and heat pumps.

The UN’s assessment determined that while informal recyclers cherry-pick some valuable elements from waste electronics and electrical equipment, 97% is improperly managed and just 3% is known to be collected and treated in facilities using environmentally sound methods.

Of the countries evaluated, Costa Rica has the highest e-waste collection of 8% or 1 kilo per inhabitant of its total e-waste generated, followed by Chile with 5% or 0.4 kg per inhabitant.

In addition to valuable materials, toxic substances were also found in the region’s e-waste. Such substances include at least 2200 kilos of mercury, 600 kilos of cadmium, 4.4 million kilos of lead, 4 million kilos of brominated flame retardants, and 5.6 megatonnes of greenhouse gas equivalents.

These elements “are poorly managed within the region and are likely to be untreated, generating various risks to the stability of a healthy environment,” the report reads.

Given this situation, the document calls on all countries in Latin America to introduce and enforce either a robust legal and policy framework focused on environmentally sound management of e-waste and persistent organic pollutants contained in e-waste, or monitor and reinforce existing systems to make them more efficient and effective.
