HEAVY DUTY by carsten in der elst uses material byproducts to forge unique objects

carsten in der elst shares his final thesis project that examines the moral and ethical responsibility of product designers. titled ‘HEAVY DUTY’, the work comprises a series of furniture pieces that have all been made using various material offcuts and byproducts.

the project by the cologne-based designer looks at the consumption of natural resources and in particular the waste materials that are formed as a byproduct. ‘by producing material goods for society, the industry is consuming natural resources – a heavy duty. inevitably, a part of the production energy is used to generate waste material, which form and potential is usually disregarded in the ongoing process. to honor every bit of these limited and valuable materials, this project is trying to redefine the existing role of the unmindful product designer. this is an appreciation of our materials and processes.’ – carsten in der elst.

the collection includes a chair made using offcuts from a stone quarry and sidetables formed using the waste material from an industrial forge. in this way, carsten in der elst explores alternative uses of what was once considered waste, and the outcome is a series of creative and beautifully raw pieces. 

to make the shotcrete collection, the concrete was shot on a substructure made of wooden offcuts and chickenwire 

to realize the project, carsten in der elst visited different production sites, which he has documented in the images here. the resources of these locations were examined and utilized to design furniture and home objects. unlike conventional mass production, the byproducts and circumstances in the collaborating companies dictated the scope of each design, resulting in unique pieces. during the project, these materials become objects with a story worth telling. the following documentation portrays the origin and atmosphere from which the product was brought to life.

‘returned objects’ one & two created from bringing disregarded products together

during the serial production of wood turn-products, b-quality goods are generated

the ‘forged sidetables’ are made with a force of 10000 kg – they weight around 50kg each

the ‘forged bowls’

while creating industrial parts for ship engines, byproducts are generated, which made the forge collection

wax furniture is made from byproduct wax that is usually sold to a pitch torch factory

during the production of candles, an indefinable mixture of paraffin, stearin and beeswax occurs, resulting in byproduct wax 

foam seats are made from the byproducts of the mattress industry

after assembling layers and cutting the (re-)built block of foam into seating objects, they are coated with polyurethane

‘aluminum skin bench’ is made from byproducts of the aluminum industry

big blocks of aluminum have a bumpy skin from the pouring process – before precise milling processes, this skin needs to be removed
