O sumagre, o arbusto da figura, estava no pequeno jardim central e é hoje quase desconhecido (infelizmente, a planta já não existe há alguns anos o que é uma interessante metáfora do tempo). Mas Portugal já foi um grande exportador de sumagre. Acontece que a flor é muito rica em taninos e era usada para curtir couro. Agora quase não há memória, mas havia equipamentos especiais para obter o sumgare, o qual era exportando nos principais portos portugueses. Os frutos secos e moídos da planta, que é agora silvestre, e já a encontrei do Algarve até Trás-os-Montes, podem ser usados como especiaria. Em Nova Iorque (a primeira vez que vi a planta) havia publicidade dessa aplicação. Curiosamente em Portugal não há notícia do seu uso culinário, o que não deixa de ser interessante. Se por um lado, não temos coletivamente memória de muitas coisas relevantes, ou as nossas memórias são distorcidas, por outro, há muito mais mundo do que a nossa imaginação muitas vezes concebe.
E depois há as estufas que estão a ser construídas há meses. Com o que parecem ser tubos de aço inoxidável e folhas de plástico. São importantes não só os materias de que são feitas, assim como a sua reciclagem e a explicação de como funcionam. Mais uma vez vez deixo isso para os leitores.
Na região de Arazede encontramos também muitos pinheiros e cacos de resina. Como funcionam, para que servem, o que se faz a partir da resina? Em Cantanhede há uma fábrica que separa os componentes da resina, por exemplo. A resina é muito inflamável e temos de ter todo o cuidado. Uma parte do trabalho é esse. Ninguém aceita, e ainda bem, que ocorram acidentes. As pessoas usam os materiais e os medicamentos sem pensar que alguém zela pela nossa segurança.

Quick chemical trail in Arazede
I pass in Arazede almost every weekend. This village has a lot of history but it not about that that I want to speak. I have noticed several things there, in particular the sumac, the water treatment plant, and the greenhouses to are being built. I will talk about them.
The sumac, the plant in the picture, was in the small central garden and is now almost unknown. But Portugal was once a major exporter of sumac. It turns out that the flower is very rich in tanins and was used to treat leather. Now there is almost no memory but there was special equipment to obtain the sumac, and this plant was exported in the main portuguese ports. The dried and ground fruits of the plant, which is now wild and which I've found from the Algarve to Trás-os-Montes, can be used as a spice. In New York (the first time I saw the plant) there was advertising for this application. Curiously, in Portugal there is no record of its culinary use, which is quite interesting. If, on the one hand, we collectively lack memory of many relevant things, or our memories are distorted, on the other hand, there is much more to the world than our imagination often conceives.
There is not much to say about the water treatment plant, one would say. Yes, in an ideal world everyone had an idea of how they worked and that they are absolutely necessary to prevent waste, even the most natural and secret, from being spilled. People hear about chemical compounds that are detected in these plants, more at the weekend, of the problems with the drugs. People only hear about problems. Of course, we can always do better. In fact, that's what scientists and technicians are working also on. You may have heard of the sludge, but perhaps never how it is dried and recycled or used. And, in addition, every day these plants must operate and prevent sewers from running around, smelling very badly, and contaminating the waters. We could talk a lot about water treatment plants, both in terms of normal and the research that is being done. I leave that to the readers.And then there are the greenhouses that are being built for months. With what appears to be stainless steel tubes and plastic foils. Not only are the materials from which they are made important, but also their recycling, as well as the explanation of how they work. Once again I leave this to the readers.
In the region of Arazede, we find also many pines and collecting of resin. How do they work, what are they for, what is done from it? In Cantanhede there is a plant for separates the resin, for example. The resin is very flammable and we have to be very careful. Part of the job is this. Nobody accepts, and this is very welcome, of course, accidents. People use materials and medicines without thinking that someone is watching over our safety.
