Abstract

Our team, Porta Possibilities, consists of four Humboldt State University Environmental Resources Engineering students. For our Engineering 215 Design class, we were given the opportunity to work with a local school, Zane Middle School, and improve their process of recycling. Our project was to improve the process that was currently in place of cleaning the recyclables from the school's cafeteria.

Background

Zane Middle School currently uses 5 gallon buckets and a simple cart to wash and transport recyclables throughout the facility. This project will focus on creating a new more portable and durable means of processing the wastes produced by the schools cafeteria.

Problem Statement and Criteria

The aim of this project is to create a more durable, transportable, and safe cart to enhance the recycling workflow for staff at Zane Middle School.

Description of Final Project

Our final project is a cart that is built for durability, transportability and efficiency. With a stainless steel sink, pneumatic tires, front-axle steering, and steel reinforcement, the SmartCart is designed for maximum durability and portability.

A fully functional sink basin is operated at a reasonable height, which limits the amount of bending and stress on one's back.

The Pneumatic tires and front-axle steering make for easy and quiet transportation, and provides a great turn radius.

Steel reinforcement makes the SmartCart stable, strong, and durable.

Project Goals

  1. Create a very durable alternative cart
  2. Improve upon the ease of portability of the cart.
  3. Enhance the workflow of the recycler
  4. Improve the overall experience of recycling wastes produced by the school's cafeteria

Design

The final design includes a restaurant grade stainless steel sink( with three sinks) for durability and ease of maintenance as well as a garden cart with pneumatic wheels on an axel for portability needs. The sink is attached to the cart with steel bars to elevate the sink and for reinforcement. The sink is equipped with a suction sealed lid for insulation and safety. Rubber hosing is attached to the underside of the sink drains for ease of disposal of used water. Metal mesh is fastened to the bottom of the cart to be used as a drying rack for washed materials. All the sinks are equipped with strainers to catch any unwanted food matter.
