Greencycle-Eco Uses Pre-fabricated Bamboo as Its Main Material

Greencycle-Eco Uses Pre-fabricated Bamboo as Its Main Material:

Greencycle-Eco is a bicycle that explores the use of our current technology, instead of high and sophisticated technology in order to reduce the production cost. The result is affordable bicycle for farmers and other lower income demographic group in Third World Countries. At the same time, this strategic implementation can also be used for First World Countries to achieve greater sustainability.

Pre-fabricated Bamboo panel products have been chosen for the Greencycle-Eco design. With the increasing demand for using greener and more highly renewable materials followed by recent technology developed in India and China, research studies and material testing on Bamboo panel products have shown positive results in the quality and mechanical strength.

Designer : Paulus Maringka

Taking into consideration production costs, the design pattern of Greencycle-Eco reduces the number of component parts to three different forms with two sets of identical parts being repeatedly cut out using CNC from a bamboo based panel product.

Standard bamboo panel measuring 1200 x 2400mm can provide enough parts for eight bicycle frames which can be cut out in a short amount of time and reduce the production cost considerably.

Using a pre-fabricated bamboo panel product as the main material for Greencycle-Eco offers a number of advantages including:

1. The product is made from a renewable material, abundantly grown and commonly available in Asian countries.


2. It has consistent good quality.


3. The overall bicycle can fit into a small flat-pack package making it economical to transport (reducing carbon footprint) if shipping is required.

The steel brackets used as a joining component, will last and can be reused while the bamboo parts can be easily and cheaply replaced when needed.

To increase the bicycle’s functionality and load capability, the following changes have been made as part of the design features of the Greencycle-Eco:

1. Frame length has been increased by 20% to create greater surface area to carry loads without compromising the stability, maneuverability and safety of the user.

1. Changing the shape of the downward angled seat stays of the traditional bicycle creates an opportunity to provide not only a support for the rear seat but the point of attachment is required to give the users a freedom. In this way, users can develop or customize their bicycle and turn this humble vehicle into a form of transportation which better suits everyone needs without compromising its functionality as a form of transportation or operational safety.

Tuvie has received this “Greencycle-Eco Bicycle” concept from our ‘Submit A Design‘ feature, where we welcome our readers to submit their design/concept for publication.

Carbon Negative Cement Wins Green Award

“If implemented, the material would take care of most of construction’s attempts at carbon reductions in one fell swoop,” says Material ConneXion Vice President Dr. Andrew H. Dent of the company’s selection for 2011 MEDIUM award. The selection, Novacem‘s Carbon Negative Cemement, replaces calcium carbonates used in typical cement formulation with magnesium silicates and uses a lower-temperature production process that runs on biomass fuels.

Typical cement is responsible for approximately 5 percent of man-made carbon dioxide; the emissions are caused by the processing of limestone and raw materials and the burning of fossil fuels.

Novacem associate engineer Daniel Bowden says that while the cement is still in development, it is already achieving strengths of up to 80 Mpa.

This autumn, the British Film Institute (BFI) has reached a major milestone in its long history of preserving the nation’s film heritage. The pioneering new building is ready to house the BFI’s entire master collection of acetate and nitrate film in closely controlled environmental conditions ideal for the long term protection of this priceless and vulnerable material.

The Project has been realized through the Screen Heritage UK (SHUK) programme, a nationwide initiative funded by the Department of Culture, Media and Sport. One of its key objectives is to prevent the deterioration and loss of the nation’s films so that they can be made accessible now and in the future. The BFI cares for the most significant film collection in the world. It represents the history of the moving image in Britain from pre-cinema through to the present day. The collection has been stored over two sites; the new building consolidates the collection into an existing site in Warwickshire.

Site Plan

The building is designed by Edward Cullinan Architects who led a detailed feasibility study which concluded that the BFI’s existing archive buildings could not be suitably upgraded, and that a new ‘sub-zero’ storage facility large enough to house all master acetate and nitrate material should be constructed at the earliest opportunity.

The final technical solution is the result of intense research and collaboration between the architect, engineers, film experts and the BFI to define the best method for storing such a large collection of film sustainably for the next 50 years and beyond.

At just under 3000 sqm, the new vaults will store up to 460,000 canisters of film in conditions of -5°C at 35% relative humidity, while the construction enables the building to sustain these conditions in an energy efficient way.

Pre-cast concrete panels provide the thermal mass required to limit temperature fluctuations. Although the building form is quite simple, consisting of 30 identical cellular vaults for nitrate and 6 vaults for acetate film, the specification requires extremely low air leakage rate and must withstand intense heat in the unlikely event of a nitrate film fire. Rigorous analysis, detailing, quality control and testing has been carried out to ensure the building will provide the sub–zero temperature, low humidity and fire prevention that the film requires for its preservation.

The building is the first of its kind to store large quantities of film in such cold and dry conditions; it will also achieve a BREEAM Rating of ‘Excellent’ for its sustainable features.
