Blog 5: Waste Photo Blog

We've been having such a lovely time exploring Sardinia, but fear not, we've spent plenty of time learning too! Here are some pictures of all things waste management:


Color-coded bales of separated plastic at the Arborea MSW handling facility. The plastic has been sorted via magnets, eddy currents, optical sorting, air jets, manual separation, and more.



A landfill for residual waste and ashes at the Arborea MSW handling facility. There is an intermediate cover, and landfill gas is burned to produce CO2 (because its methane fraction is too low to be used for energy recovery).


 
Metals Separation at Sardinia Bio Energy - a magnet is used to separate metals from the biomass before it is sent to the combustion chamber.



Air pollution control devices (and me!) at Sardinia Bio Energy. 3 cyclones and a baghouse with 1700 bags are used to manage air pollution. Lime is injected to remove acidic components from the flue gas and improve utilization.


Mission Control for the Sardinia Bio Energy facility - someone is here 24/7 to ensure the system is running properly.

Food waste (pasta, bread, and more!) to be anaerobically digested at Su Stai. Specific proportions of food and yard waste are fed to the digestor to ensure ideal conditions.

Blog 1: Expectations

I am incredibly excited to travel to Italy! This is my first time traveling outside of the United States, so I don’t have any previous experience being in another country and immersed in their culture. Because I am not a practiced traveler, it might initially be a bit difficult to adjust and navigate typical travel difficulties, such as the language barrier, cultural understanding, and just jet lag. However, I am very open and eager to try new things, and hope to gain as many new experiences as possible. I look forward to trying new foods, exploring Sardinia, and learning about the language and customs. I am especially excited to engage with various people and hear their stories. Beyond our group excursions, I hope to explore the landscape by going on runs around Cagliari. I will actively seek out opportunities to venture beyond tourist experiences and learn about Sardinia’s lifestyle, history, and culture. As far as my expectations and preconceived notions about Italy, I have heard am

Blog 4: Sulcis and Carloforte

My, my, my.... where to even begin!  Ou r first weekend trip was absolutely incredible. We started off strong with the land rover ride - our carpool energy was UNMATCHED. We made our way through 2000s classics (Baby is still stuck in my head), country (Annalisa's fave), Spanish music (thank you Ian!), and more. Here's a pic of the band (first album coming soon): Voices tired and spirits high, we got off the rovers at our first stop - a mining complex named Montevecchio of the Medio Campidano province in the Arbus/Piscinas area. This complex was central to mining in south-west Sardinia, and is now a UNESCO world heritage site. We got a glimpse of the mining lifestyle (the 6-person lift system, the tools involved, the minerals - lead and silver - in demand, the associated dangers, and more). Then we channeled our inner 7 dwarves/District 12/Minecraft energy, donned our hard hats, and ventured down into the mines to explore: After our underground adventure, we hopped back in the r

Blog 6: Sinis & Bosa

 Aaaaaand we're back from another wonderful, mind-boggling weekend adventure! Last weekend was a hard one to follow, but it (somehow) has been topped! Here's what we we've been up to: First up, a bonus beach! Not technically apart of our weekend excursion, but we went to Chia on the southwest coast on Saturday! Snorkeling, exploring the rocks, and swimming for a few hours made for a lovely start to June: The next morning, we were off to Bosa on the western coast. We wandered the pretty streets, popped into some cool artisan shops, stood in tiny doorways, and met some friendly cats - all while listening to rock music from the "Bosa in Rock" festival along the river. We had a nice lunch along the Temo River (accompanied by a Kiss cover band) and walked up to the Malaspina castle at the top of the hill to get a view of town and the water:       Leaving Bosa to the tune of "Don't Stop Believin'", we headed to the Sinis peninsula area and my favorite
