Concentrating on value

In an earlier post we posed the question why fluorescent powder from waste light bulbs, which could be said to contain higher concentrations of heavy rare earth elements (REE) than virgin rock ore that is being mined, is not economical for urban mining. The question is worth revisiting in light of recent developments. The first has been some new research by … Continue reading

Recycling rare elements in lamps

A reason for energy efficient lamps being important for resource efficiency and circular economy agendas has much to do with the rare and critical elements found in fluorescent and LED lamps. Rare earths are used on the phosphor coating of lamps to produce soft white light (a well as other colours of light). While rare earths for lighting only account for 7% of the global … Continue reading

Where do all the lamps go?

One question I heard asked many times, and have asked myself, is where do lamps go after I have brought them for collection?  In Sweden (and currently also Norway and Denmark), the answer is Nordic Recycling in Hovmantorp. Household collection from apartments and other collection sites is aggregated in the same yellow bins found at the recycling centers and transported … Continue reading

The traditional business of light

With the latest developments of LED technology with increased product lifetimes and integration into smart systems, there has been increasing focus on the idea of servicizing lighting. This is a far cry from the traditional lighting industry model with its focus on the product and power consolidated in the hands  of the big three producers) was so great, that producers … Continue reading

IKEA reversing material flows?

We’ve given attention to Samlaren being unveiled in Sweden, but we should also mention other similar initiatives aimed at increasing household collection of lamps in Europe. One such initiative is the reverse vending machines being installed in select IKEA stores in the UK and Denmark.  The idea is simple. Similar to deposit refund or pant machines, these machines give an incentive … Continue reading

Lighting and the environment – the global perspective

I mentioned in an earlier post about the phase out of inefficient lighting in many countries around the world (shown in the map from UNEP above) and the need to ensure we are recycling and dealing with used lamps in an environmental sound manner (countries with some measures in place are shown in the map from UNEP below). It might be worth … Continue reading

What’s the big deal with small lamps?

In much of the literature around recycling light bulbs there is mention that many consumers are unaware that they can and should recycle these products when done with them.  Because they are small, it is often easy to just throw them in the rubbish bin. However, like other e-waste light bulbs contain metals, glass, and other materials that can be recycled … Continue reading
