Alternative natural materials are natural materials like rock or adobe that are not as commonly used as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering. The main purpose of using such materials is to minimize the negative effects that built ...
The structural properties of this material are similar to those of Portland cement-based mortars: it has an elastic modulus of 293.9 MPa, and a tensile strength of 3.6 MPa (the minimum required value for Portland-cement based concrete is approximately 3.5 MPa); [2] however it has a fracture energy of 170 N, which is much less than most standard ...
When used in prefabricated blocks, hempcrete acts as a carbon sink throughout its lifetime. [5] [6] The result is a lightweight, insulating material, finishing plaster, or a non-load bearing wall, ideal for most climates, since it combines insulation and thermal mass while providing a positive impact on the environment.
Papercrete's R-value is reported to be within 2.0 and 3.0 per inch (2.54 cm); [2] papercrete walls are typically 250 to 300 mm (10–12 in) thick. Unlike concrete or adobe, papercrete blocks are lightweight, less than a third of the weight of a comparably-sized adobe brick.
Straw-bale construction is a building method that uses bales of straw (usually wheat [2] straw) as structural elements, building insulation, or both.This construction method is commonly used in natural building or "brown" construction projects.
Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings through improved efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the ...
Wood production emits less CO 2 than concrete and steel if produced in a sustainable way just as steel can be produced more sustainably through improvements in technology (e.g. EAF) and energy recycling/carbon capture(an underutilized potential for systematically storing carbon in the built environment).

Bioplastic panels, made from blends of natural fibers and biopolymers, provide an eco-friendly option for wall cladding and partitioning. These materials are lightweight, durable, and can be designed to mimic traditional materials like wood or stone. Formwork Bioplastics are increasingly used in formwork for concrete casting.
