“Construction materials can be composed of many types of waste and be beneficial in resource management. There are predictions that use of organic waste materials can help reduce levels of waste. Building materials may be made up of waste from maize, potatoes and bananas."

The construction industry relies heavily on raw materials. Re-imagining the use of organic waste streams can offer lower-cost materials to the industry. There have been advances that can make it possible to create mushroom bricks and derive insulation from waste potatoes. Agricultural waste products that can be used within construction materials include:
  • Potato peels- This organic product can be used in the manufacturing of an acoustic absorbent insulating material that is water repellent, fire resistant and low-weight.
  • Banana leaves and fruit- The high strength fiber can be used in the making of rugged textiles.
  • Peanut shells- Shells can be a raw material that may be incorporated into the production of materials such as low-cost partition boards that are both moisture resistant and flame retardant.
These waste products are often discarded. It has been reported that food waste amounting to 60 million tons goes into landfills and could be used in the manufacturing of building materials.

Planning for a Sustainable Future with Agro-waste Construction Materials
The construction industry may be able to successfully deal with shortages in resources and increased prices for materials by looking at the potential of agro-waste construction products. Such products may offer practical solutions when it comes to long-lasting construction materials that are gentle on the environment and in some cases, such as with concrete, help reduce global carbon dioxide emissions when used as an alternative.

Everyone, from construction companies, agricultural interests, investors and homeowners should all be aware of sustainable agricultural waste products. These products, when used in various ways, construction being one, can not only help the environment, but potentially also the pocketbook
