Answer Stats

Hint	Answer	% Correct
Actions to Achieve Circular Economy	Biological Cycle Technical Cycle	0%
Life Cycle Costing (LCC)	Calculating cost throughout life cycle of a product/object	0%
Carbon recovery - Cellulose	Cellulose fibre in ww from toilet paper Uses: Soil conditioner, biomass fuel,raw material for paper pulp Tech: Advanced pretreatment of WWTP inlet, fine mesh sieves.	0%
Resource Loops Circular Economy	Closing; creating a circular flow resources Slowing; extending a products useful life Narrowing; efficient use of resources	0%
Carbon recovery - Biopolymers	Convert carbonaceous matter into PHA (polyhydroxyalkanoate), a fully biodegradable biopolymer Replacing fossil fuel derived polymers Uses: Water bottles, bags Tech: Fermentation of sludge to produce volatile fatty acids, feed to PHA accumulating organisms. Recover from organisms	0%
Circular Economy Assessment	Define inflows and outflows: water, carbon, nitrogen and phosphorous balance. Core Indicators % recirculation of outflow to biological cycle % water discharged to quality requirement Nutrient extraction from water Recovery rate of nutrients from ww Value indicators Represent economic value as well as environmental and societal value	0%
Social LCA Outcomes	Social hotspots Identify key areas of social impacts within object of analysis Highlighting social benefits directly associated with system Comparing social outcomes across supply chain stakeholder	0%
Life Cycle Sustainability Analysis	E-LCA + LCC + S-LCA People, planet and prosperity	0%
Principle-Based Circular Economy	Eliminate waste and pollution Circulate products and materials Regenerate nature	0%
Social Sustainability	Fostering well being, equity and access to resources for all people: health, education and rights.	0%
Composting and Anaerobic digestion	From WWTP; biogas, digestate for soil improvement	0%
Life Cycle Assessment Framework	Goal and scope definition Inventory analysis Impact Assessment Interpretation	0%
Inventory Ananlysis	Identify and quantify the use of energy, water and materials along with environmental releases	0%
Sharing	Increases utilisation of products	0%
Regeneration	Instead of continuously degrading nature, build natural capital. Ensures bioresources are returned to biosphere	0%
Maintaining	Keeps product in original form, maintains functionality Diverting products to other customers	0%
Value-Based Circular Economy	Maintains the circular flow of resources by, recovering, retaining or adding to their value whilst contributing to sustainable development	0%
Cascading	Makes use of products and materials for multiple purposes as they degrade in quality from high value to low value applications, before being returned to the biosphere	0%
Farming	Manage farms and other sources of biological resources in ways that create positive outcomes for nature E.g Improve biodiversity, organic fertilizers	0%
Biological Cycle	Materials that can biodegrade and be safely returned to the earth	0%
Functional Unit	Measures the functionality of a product or service system, enabling fair comparison Standardizes LCA results across products, services or systems	0%
Water recovery	Membrane filtration, water suitable for irrigation industry, non-potable urban uses Tech: Ultrafiltration, Reverse osmosis	0%
Current economic model risks	Population growth Energy consumption Water consumption Climate and ecosystem changes	0%
Circular Economy Methods	Principle-Based Action Based Value Based Resource Loop	0%
Impact Assessment	Procedure for classifying and characterising environmental impacts Key Analytical Methods: 1. Contribution Analysis 2. Sensitivity Analysis 3. Perturbation Analysis 4. Uncertainty Analysis	0%
Circular Economy	Procurement Manufacturing Consumption Recycling Disposal	0%
Economic Sustainability	Promote economic growth and development while ensuring resources are used efficiently and responsibly.	0%
Action-Based Circular Economy	Refuse Rethink Reduce Reuse Repair Refurbish Remanufacture Repurpose Recycle Recover	0%
Biological Cycle methods	Regeneration Farming Composting and anaerobic digestion Cascading Extraction of Biochemical feedstocks	0%
Technical Cycle	Relevant for products that are used rather than consumed, focusing on how each step allows materials to remain in use rather than becoming waste	0%
LCA Limitations	Resource intensive - takes long time and lots of data. Focused results - Environmental performance but not functionality, cost effectiveness etc. Not a sustainability tool Model-based	0%
Environmental Sustainability	Responsible use and protection of natural resources through conservation, renewable energy, reducing environmental harm and ensuring ecosystem remain healthy for future generations	0%
Refurbish/Remanufacture	Returns products to good working order; restores value. When products can't remain in circulation so undergo changes.	0%
Technical Cycle Methods	Sharing Maintaining Reusing/Redistributing Refurbish/Remanufacture Recycling	0%
Water Sector - Circular Economy	Shift WWT to maximise recovery of resources	0%
Linear Economy	Short term gains from selling as many products as possible Not designed for end of life use; throwaway culture Increases resource scarcity	0%
Nitrogen recovery - Ammonia stripping	Sludge treatment produces ammonia rich stream, usually returned to wwtp, increasing removal burden. Uses: fertilisers Tech: HANSA engineering, converts ammonium ions to ammonia using temp and pH	0%
Life Cycle Assessment Applications	Strategic planning Eco-design Eco-labelling	0%
Phosphorous recovery - Struvite Precipitation	Struvite ppt can clog pipes; reduce efficiency Uses: fertilisers Tech: Ostara Pearl, anaerobic reactor encouraging biomass to release phosphorous.	0%
Extraction of Biochemical Feedstocks	Taking both post-harvest and post-consumer biological materials as feedstock. Uses biorefineries to produce low-volume high value chemical products.	0%
Recycle	Transforming products into basic materials and repurposing/ reusing them	0%
Interpretation Phase	Types of analysis used to address the objective defined in goal and scope phase	0%
Energy - Biogas recovery	Upgrade biogas to almost pure biomethane Higher value product Tech: Membrane separation, pressure swing adsorption	0%
Recoverable resources WWT	Water Energy - Biogas upgrading Nitrogen Phosphorous Carbon- Cellulose, Biopolymers	0%
Goal and Scope	What is the purpose, system boundaries, accuracy, assumptions	0%
