Soil Kitchen is a temporary, windmill-powered architectural intervention and multi-use space where citizens enjoy free soup in exchange for soil samples from their neighborhood. Soil Kitchen offered free pH and heavy metal testing and produced a Philadelphia Brownfields Map and Soil Archive. In addition to serving soup and testing soil, the building is a hub for exchange and learning; free workshops including wind turbine construction, urban agriculture, soil remediation, composting, lectures by soil scientists and cooking lessons.

¿ espiga ?
Si encontramos un palet con esta marca nos tiene que dar cierta tranquilidad. Esta marca es de uso obligatorio para todos aquellos productores que quieran cumplir ley que regula el control de la madera que se utiliza para el transporte internacional así como su tratamiento fitosanitario. Ahora bien, dado que se pueden dar dos tipos de tratamiento y uno de ellos incluye la utilización de bromuro de metilo y siendo como es una sustancia perniciosa para el medio ambiente, aconsejo decantarse por maderas de palets que utilicen el tratamiento térmico para su desinfección. En su parte derecha lleva:
El código ISO del país exportador. A España le corresponden las letras ES.
El código de la empresa de tratamiento
El código del tratamiento fitosanitario aplicado (YY) que puede corresponder a alguna de las siguientes abreviaturas:
HT = tratamiento térmico de 56°C durante 30 minutos.
HT KD = tratamiento térmico de secado en horno. MB = fumigación con bromuro de metilo.

In the world we live in, data drives activism. The dialog online has reached a deafening roar and everyone has a cause, so it takes hard evidence to turn heads. We do not have access to the technology that builds $50,000 air quality sensor systems, but we do have the ability to put 50,000 $100 sensors systems into a city, a collective voice which won’t be able to be ignored.

The Microbial Home by elisaltarina

The Microbial Home Probe project consists of a domestic ecosystem that challenges conventional design solutions to energy, cleaning, food preservation, lighting and human waste.
Creating a cyclical eco-system
In the Microbial Home Probe we adopt a systemic approach to many of the domestic processes we take for granted and ask questions about how we deal with resources. It is a proposal for an integrated cyclical ecosystem where each function’s output is another’s input. We view the home as a biological machine to filter, process and recycle what we conventionally think of as waste – sewage, effluent, garbage, waste water. The Probe suggests that we should move closer to nature and challenges the wisdom of annihilating the bacteria that surround us. It proposes strategies for developing a balanced microbial ecosystem in the home.

Bio-digester kitchen island – biomethane to power the house by elisaltarina

The bio-digester kitchen island is the central hub in the Microbial Home system. It consists of a methane digester which converts bathroom waste solids and vegetable trimmings into methane gas that is used to power a series of functions in the home. The bio-digester hub is designed as a repositionable kitchen island, including a chopping surface with vegetable waste grinder, a gas cooking range, a glass tank that shows energy reserves and glass elements showing pressure, volume and readiness of compost sludge. Materials used in the design are copper, cast iron, glass and bamboo. ‘Bio-gas’ is produced by developing a culture of suitable bacteria living on organic waste material from the home. The gas the bacteria generate is collected and burnt. This arrangement is called a methane digester and it has been used in various configurations for centuries. The gas from the methane digester in the Microbial Home is fed to a cooking range and gas mantle lights. Water pipes are preheated by the digester and channeled to other components in the Microbial Home system. The digester needs a constant supply of waste material and water. The dehydrated sludge residue from the digester can be safely removed and used as compost. via Martin de re:farm
