Cecilia Lalander

I work with different biodegradable waste fractions, such as food-, toilet-, and food industry wastes. The focus of my work is on black solider fly larvae conversion, in which animal feed (larval biomass) and an biologically active organic fertiliser (treatment residue, called frass) is generated. This treatment follows the principles of circular economy, in which the waste or residual stream in one process becomes the raw material in another process. For more information about our research on resource recycling from biodegradable waste, visit our blog.

I am course leader of the 5 credit course Waste management. I also teach in the courses Safe nutrient recycling and Sustainable technologies for low- and medium income countries.

The focus of my research is on recycling of resources from biodegradable waste. Our hypothesis is that inadequate management of biodegradable waste globally, largely is due to the high cost of treatment, which exceeds the possible revenue from the products generated. We believe that if more valuable products were generated, the management of this waste fraction would improve. The technology we work with is fly larvae composting, and we use the larvae of the tropical black solider fly (Hermetia illucens) to convert biologically degradable waste into larval biomass that can be used in animal feed, and a treatment residue (frass) that can be used as an biologically active organic fertiliser. In my research, I investigate the impact of process parameters on the treatment efficiency, I evaluate the efficiency of different waste sources and possible ways of improving the treatment efficiency, with e.g. pre-treatment schemes. As this is a close loop system, the fate of contaminants is of importance and this is something we put great emphasis on as we want the circulation of resources to be safe. Another important factor we also investigate is the environmental impact, e.g. by measuring the direct emissions of greenhouse gases in the treatment.

We also work with implementation of this technology in Sweden as well as other parts of the world (currently Rwanda and China).

We are currently involved in the large-scale implimentation project The feed of the future for fish, pigs, poultry and laying hens. More information about the project can be found here. 

This project is a continuation of the research project Five tonnes of green fish in the counter, in which four tonnes of rainbow trout were fed circular feed, in which  insects were the major protein source. The larvae were reared on vegetable cuttings from Grönsakshallen Sorunda, and reclaimed bread from Fazer.

I hold a PhD i Chemistry from Monash University, Melbourne, Australia.
