A
concept of sustainable water-energy-environment nexus has been developed for thermal bioenergy conversion processes
as shown in Figures 1 and 2. Two case studies are performed in a biomass-fired CHP plant and a waste incineration
unit, which intend to approve and implement the concept. The main results from the case study on stormwater issues in
biomass-fired CHP plant show that the biomass fuel storage can play an important role in the sustainable development for
the water-energy-environment nexus. It has been proved that the water adsorption capacity of wood chips can be used as a
buffer to reduce water runoff, to extend the time for natural water evaporation, to receive the recycled runoff water without
significant impacts on fuel quality. The runoff water absorbed by the biomass fuels could increase heat recovery and water
reuse. The results also indicate that it is possible to achieve near zero water runoff and wastewater emissions in the tested plant
area by an integration of stormwater management with the bioenergy conversion processes. Another case study is focused on
a closed water loop in Waste-to-Energy (waste incineration) unit. The closed water loop can properly integrate the thermal
energy conversion with an efficient flue gas cleaning, cost-effective water treatment and energy-effective water recovery. The
investigation shows that it is possible to achieve a near zero wastewater discharge, which could also result in a significant
amount of water recovery for internal usage. The two case studies demonstrate that sustainable water-energy-nexus could be
set up in biomass energy conversion processes, which can provide good solutions handle important issues associate with water
resource, energy efficiency and emissions to air and waters in bio energy conversion processes.

Minimising storm water discharge could be achieved by a water balance through water retention, water evaporation in biomass fuel storage. The
recirculated runoff water by biomass fuels can further enhance heat and water recovery in flue gas condensation.
