Feasibility of Pelletizing Sludge Product for Burning and Agricultural Uses from Paper Mill Process Effluent

Domestic demand for wood pellets in Cape Breton, Nova Scotia has dramatically increased in recent years. Consumer angst resulted in one retailer trucking three tractor trailer loads of bagged pellets last winter (2014-2015) from British Columbia, which sold out in a few days.

Data Centre Waste Heat Recovery for District Energy Systems

Data centres generate a large amount of heat, from operating computers 24/7. This heat is normally wasted and released outside the data centre building. This research will determine the best way to capture the waste heat from a data centre and distribute it to other buildings in the area that require heating. The vessel for this distribution of heat will be a network of water pipes, just like an electrical grid distributes power to multiple buildings. The intern will provide insight on the equipment and system design required to capture the waste heat in an energy and cost efficient manner.

Mechanical and physical beneficiation of concentrates from printed circuit board processing

E-waste is one of the fastest growing waste streams in the world in terms of volume and its environmental impact on the planet. Printed circuit boards represent a major portion of the e-waste that contains higher values. The metal fraction from the circuit boards is extracted for its value while the non-metal fraction is often landfilled. The proposed research looks into the disposal guidelines for landfills and incineration and quality requirements for being used as a filler and secondary materials source will also be studied.

Adsorption of tannins on copper surface

Tannins, natural renewable molecules, have exhibited excellent corrosion inhibition properties, comparable to those of non-renewable counterparts. TGWT Clean Technologies Inc. has a portfolio of tannin-based corrosion inhibitors, which are being used in industry to protect mild steel (MS) steam boilers, high efficiency condensing aluminium boilers, as well as multi-metal heating and cooling closed-loop systems. Copper equipment is ubiquitous in industry, e.g. heat exchangers.

Acoustic detection of fish presence and depth distribution at the FORCE tidal energy test site in the Bay of Fundy: assessing risk of interaction with tidal turbines

Tidal energy turbines are a new renewable energy technology that will be demonstrated at the FORCE test site in the Bay of Fundy. The potential negative effects of these turbines on fish are of high concern to industry, regulators, fishers, and other stakeholders. This research will use sonars attached to sensor platforms deployed on the sea floor at the FORCE tidal energy test site to evaluate the risk that tidal turbines pose to fish. Risk will be based on where fish are naturally located and where the turbines will be operating.

Minimizing potential induced degradation in crystalline-silicon based photovoltaic solar modules – Year 3

The demand for photovoltaic solar modules has increased tremendously in recent years. Unfortunately, photovoltaic solar modules are prone to potential induced degradation, i.e., a decrease in the power delivered from such modules arising as a consequence of them operating continuously under high applied voltages. This project aims to design a protocol for the accelerated testing of solar modules; we want to speed-up or accelerate the aging of these solar modules in order to identify what materials and configurations in a solar module are less prone to potential induced degradation.

Development of Novel Power Take Off and Control Scheme for a Canadian Wave Energy Converter

In the proposed project, an exploratory study will be conducted on the control concept and WEC design developed by P2H2P in order to prove its viability for energy recovery from the waves. For this purpose, a time domain model and unique control system will be constructed considering the particularities of the design, as provided by P2H2P. The outcome of this project will be the predicted power output from the WEC in the typically sea states that occur off the West Coast of Canada, alongside the expected annual energy generation from this concept.

Development of efficient and inexpensive thermal storage “on demand” for Dish/Stirling System

In this project we aim to study means of development of a new concept of the thermal energy storage (TES) technology which allows for the collection of thermal energy for later use. With the Solar Power System it is necessary to balance energy demand between day and night time. On the one hand, TES can help improve the performance of a power generating system by achieving full load operation of the thermodynamic cycle at high efficiency. On the other hand, demand for energy for personal needs is unsteady during the day.

Production of Healthy DAG-Enriched Oil from Canola Using Supercritical Carbon Dioxide Media in Par-Baked Frozen Dough Products

Structured lipids, specifically diacylglyceride (DAG) oils, have potential to replace trans fats and oils high in saturated fats such as palm and thus provide healthier oils with improved functionalities and sustainability. However, they are produced using costly and environmentally unfriendly “enzyme in solvent” systems, and have shortcomings when utilized in certain food applications. DAG oils are clinically claimed to help reduce fat accumulation and can have a major impact on obesity, which is currently identified as a global health risk by the United Nations World Health Organization.

Improving Process and Product Performance through Innovative and cost effective solutions

EHC Global - our industry partner, is a worldwide industry leader in design and manufacture of escalator handrails and many other products for the lift industry. They mainly deal with thermoplastic polyurethanes (TPUs), which are versatile engineering polymers with a wide range of applications, however processing of TPUs is a complicated and challenging task. The complications arise from the relatively high melting temperature of crystalline hard blocks and the degradation and crosslinking that take place at temperatures slightly above melting temperatures.
