Characterization of Complex, High-Moisture Waste Streams (Pumping Station Analogue): Execution of WACS specifically designed to assess the composition and treatment potential of riverborne waste collected from waterways. This experience is highly analogous to the required WACS at Metro Manila Pumping Stations as the samples involved highly entangled materials, significant organic matter, sand, and stones. The detailed analysis identified recovery opportunities and guided the design of mechanical systems capable of sorting complex, wet streams, providing critical design input for future large-scale facilities.

An organisation that is collection waste from a river in Guatemala is looking for solutions to sort and valorise this waste. But river waste is a difficult stream to sort, as the waste is mixed and entangled with organic waste, sand and stones. In a ‘Minimum Viable Product’ sorting setup, SweepSmart is implementing an improved sorting lay-out, including testing ways to support the manual sorting with a shaking sieve.

What's great about it? 

• Pioneering solutions to improve and mechanise river waste sorting at a small scale with minimum investments
• The learnings of the MVP can be incorporated into a large-scale sorting set-up to sort the majority of the waste removed from the river.
