Recycle of Nitrogen and Phosphorus in Hydrothermal Liquefaction Biochar from Galdieria Sulphuraria to Cultivate Microalgae
Background Energy demands have been increasing in recent years with the growing global population. Bioenergy is considered a vital component of addressing these growing demands and minimizing greenhouse gas (GHG) emissions. Recent research on bioenergy has shown that algal biofuels have potential as a feedstock to counter the effects of food in comparison...

AirDuo-Carrier
Background Recent research focused on sources of volatile and semi-volatile organic compounds has uncovered a new source of these compounds in which they are released into the atmosphere in the forms of gas or aerosol. Various composites emit gaseous compounds considered as non-combustion sources. However, these compounds emit submicron atmospheric...

Sorbent-Based Oxygen Separation for Energy Storage Systems
Background Thermochemical energy storage has many practical implementation challenges, one of which is creating and maintaining a low oxygen partial pressure (pO2) during the thermal reduction step. In order to reduce the pO2, current approaches are to either purge the reactor with an inert sweep gas, or vacuum pumping. However, both of these approaches...

Efficient Depolymerization of Polyethylene-Based Plastics
­Background Discarded polyethylene-based plastics are not usually recycled because of their resistance to depolymerization due to stable carbon bonds. Pyrolysis is a quick thermochemical treatment technique that destroys plastic structures and turns them into fuels and chemical products. For the pyrolysis process, however, feedstock drying is required,...

Algal Biochar as an Asphalt Additive to Resist Ultraviolet Aging
Background Asphalt aging is implicated in many distresses of materials reported in the roofing and paving industry. Among the issues brought on by excessive ultraviolet (UV) aging are increased susceptibility to thermal cracking due to excessive hardening and loss of stress relaxation capacity in aged bitumen, the binding component in roof shingles...

Hybrid Asphalt Bio-Modifier Combining High-Protein and High-Lipid Feedstock
Background Bitumen in asphalt pavement is subject to irreversible oxidative aging that results in unwanted stiffening and heightened risk of cracking. These conditions occur when the components within bitumen increase in polarity, causing agglomeration and forming nano-aggregates. Although modifiers have been successful in softening aged bitumen, the...
