"A new community housing development in the Bronx will feature a cool piece of kit: an on-site aerobic digester that can turn 1,100 pounds of food scraps into 220 pounds of high-quality fertilizer every single day.
Built by Harp Renewables, it’s basically a big stomach filled with bacteria that breaks down food scraps and wasted food into their component parts, and in the future could be a standard part of all apartment units as the amount of food waste in American reaches 30% of the total mass of all trash collection.
The Peninsula, organized by Gilbane Development Company, will feature 740 units of affordable housing, 50,000 square-foot light industrial space and equal sized green space, and 15,000 feet of commercial space, all of which will send their castaway comestibles right into the digester...
Fast Company reports that Christina Grace, founder of a zero-waste food management company, helped plan the design and implementation of the digester into The Peninsula, and helped organize a 40% grant from the city to pay the $50,000 upfront cost.
“The goal is for this material to work its way into the community garden network in the Bronx,” [Christina Grace, who helped plan the design] told the magazine, adding that she expects it to pay for itself over just a few years. “We see this as highly replicable in both commercial and residential venues. We know there’s a need for fertilizer.”
Producing fertilizer right there in the city reduces the need for it to be trucked in from afar, chipping away, even if just a bit, at NYC traffic.
Big problem solver
Perhaps uniquely beneficial to New York City compared to other spots in the U.S. is that the digester will have a significant impact on the Bronx’s share of the city’s rodent problem.
Those who’ve watched the Morgan Spurlock documentary Rats will understand why that’s significant—while those that haven’t will have to imagine what living in a megacity where rats outnumber people by around 8 or 10 to 1 looks like.
Another big problem the bio-digesters could potentially help is pollution and greenhouse gas emissions. Fertilizer is a big emitter of all three of the most-targeted GHGs. Fertilizer, like quarry dust and ammonia is, like so many commodities, often imported from countries who specialize in its production, such as Norway, but also Russia and Ukraine, whose conflict has recently highlighted the fragility of the supply chain with sharp increases in prices...
Bio-digesters by design keep the CO2 and methane in the fertilizer produced, rather than it entering the atmosphere.
For these reasons and more, the aerobic bio-digester is slowly making its way into residential and industrial spaces around the country.
GNN reported on an enormous bio-digester at the heart of the D.C. advanced resource (sewage) recovery center outside the capital, and on the use of bio-digesters on Australian pig farms which are helping reduce the environmental and psychological impact of the effluent produced from such operations.
Harp Renewables tweeted how happy they were to have installed their bio-digester in the town of Cashel, Ireland.
Expect to see more stories like this pop up around the globe."

Note: Obviously gentrification bad and "affordable housing" is sometimes nowhere near as affordable as it should be, etc. etc. That said, this is such a fantastic use case that I felt I had to post it anyway.

Decorative Sunday
The Decorators Supply Corporation of Chicago traces its history back to 1883 when the original founders established a partnership to manufacture "artistic decorative accessories." Ten years later, Decorators Supply had blossomed into a successful business, manufacturing cast ornamental plaster that helped create the mouldings for the buildings of the "White City" at the World's Columbian Exposition of 1893.
Today, Decorators Supply is still a family-owned business. It maintains the largest repository of moulds used to cast period architectural details in two historic materials: wood composite and plaster. From these materials, they create historically accurate architectural mouldings, ceiling medallions, capitals, pilasters, corbels, furniture, woodwork appliqués and fireplace mantels. Examples of such decorative architectural features can be found in the company’s 1925 Illustrated Catalogue of Plastic Ornaments Cast in Plaster for Interiors and in Composition for Exteriors shown above, their catalogue #118. The catalogue consists of 320 black and white photographic pages of the company’s stock.

This architecture study is based on a shot of Ricardo Bofill's La Muralla Roja. The photograph was taken by Marta Rubio, just like the one that inspired the first one I executed almost a year ago.
The illustration is executed in Procreate, on an iPad Pro 12.9" with an Apple Pencil 2nd generation. I used True Grit Texture Supply's Chromagraph pencil brushes (concept sketcher for the line work, Deutsche Kolorist Toothy for the color work).
