Design teams up with R&D to create a gamified recycling bin as part of an interactive recycling initiative for Pepsi. Tiff and Darshan meet with Rick to plan how to scientifically measure changes in recycling rates. The Design team and interns brainstorm what encourages people to recycle and create ideas for three prototypes: a visual response steampunk design bin, a gamified bin with a launcher element, and a compliment bin which pays you a compliment for recycling. After hearing Raj is learning how to drive in the United States, Andrew and Stephen offer to be his instructors. But first, Rick and Stephen head to Palmer Square to measure for a recycling rate baseline. Back at TerraCycle, Tiff, Darshan and the interns are racing to build their three prototype bins by the end of the week. Raj has his first driving lesson with Andrew and Stephen where he learns the rules of the American road. Rick, Tiff and Darshan return to Palmer Square to test the three prototype bins. Despite having the lowest success rate, Pepsi favors the compliment bin and its scalability. Tiff and Darshan get to work on the final compliment bin, as the prototype needs a lot of work. After work, Raj practices parallel parking with Andrew and Stephen one last time before his driver"™s test. Design team gets the final compliment bin up and running just in time for one final test. Despite Andrew and Stephen"™s efforts, Raj fails his driver"™s test. But, there is always next time! Tiff and Darshan present the final bin to Pepsi, and Rick presents the data. The bin has increased recycling by 28% percent, and Pepsi is pleased with the results.

The Zero Waste team lands a major deal with Loctite, the world"™s largest adhesive brand. Tom stresses the importance of this deal; finding a solution to recycling industrial adhesives will open the doors to other potential clients. R&D must tackle this complicated science by finding a way to recycle Loctite bottles and the residual adhesive that remains in the bottles. After eavesdropping on Andrew and Dean"™s conversation, Gina tries to grill Andrew for details about his girlfriend, Alicia, but Andrew maintains his right to privacy. Rhandi is feeling the pressure as the Loctite project deadline approaches, while Rick and Ernie struggle to find a solution for solidifying or curing the residual adhesive inside the bottles. Since the adhesive is anaerobic, they hypothesize they"™ll need an oven. Without the budget for an oven, Rhandi redirects Rick back to the resources he has available in the lab. Desperate for anniversary gift ideas, Andrew breaks down and asks Gina for advice. Rhandi meets with Graphics to discuss package design for the Loctite Zero Waste Boxes. They reach a roadblock when Rhandi realizes she"™ll need handling instructions from R&D before they can move forward with packaging. During lunch, Dara and Tiff inquire about Andrew"™s upcoming anniversary plans and offer their two cents. Struggling without an oven, Ernie and Rick attempt freezing the adhesive to remove it from the bottle. Stephen finds himself as the intermediary between Rick and Rhandi on the Loctite project. After bargaining with Rhandi, Stephen sources an oven for R&D and they successfully cure the Loctite adhesive. Rhandi, Rick, and Ernie pitch the sales plan and recycling solution to Loctite, and they"™re eager to move forward with the program. Andrew"™s girlfriend Alicia stops by Terracycle and meets Dara and Gina. Andrew surprises Alicia with the earrings in the parking lot; she loves the gift and his thoughtful gesture.

Last year"™s upcycled Art Show is returning for a second year and Tom has plans to make it bigger and better than ever. Tiff and Darshan are commissioned with curating the show by selecting featured art from independent artists, creating art pieces for five brands, AND creating signage. With an overwhelming workload and a limited timeframe, Tiff and Darshan enlist the help of four new design interns to create the branded pieces. During an office lunch, Stephen surprises everyone with his homemade lunch and his passion for cooking. Tiff and Darshan spitball ideas for the art pieces, and Gina offers to create an art piece using her fashion expertise. Gina and the design team take a fieldtrip to the warehouse to collect materials for the art pieces. Stephen works on curating his own art by selecting a filter for his Instagram food pictures. Tiff and Darshan collaborate with the interns to build upon their branded art ideas for the clients. Gina begins work on her upcycled dress, but soon becomes noticeably absent from the design garage. While microwaving his lunch, Stephen observes Tony and Rhandi"™s "œfancy lunch club." He works up the courage to inquire about membership, but Tony and Rhandi aren"™t going to make it easy. Stephen must prove his cooking skills to Rhandi and Tony to earn a seat in their exclusive lunch club. Tiff and Darshan select independent art pieces for the show and notice the lack of progress with Gina"™s dress. They meet with Gina to discuss her workload and Tiff offers to help her finish the dress. Stephen presents Rhandi and Tony with his prepared dishes; they are impressed with his cooking skills and officially offer him a seat at the table. Minutes before the Art Show, Tiff and Gina realize the dress is too short but come up with a last minute solution. Gina and Tiff"™s upcycled outfits are a hit, as well as the branded pieces designed by the interns.
